K-Line Heavyweights

Ben, I had a similar problem when adding pickup rollers to a Williams tender. Even the shortest pickup the roller would hit the axle so I just put a wrap of kapton tape over the axle. The roller still has more the tenth of an inch space on normal track but I was concerned any uneven track might cause contact. Now, no worries.

I have KLine Penn heavyweights and not which design the trucks are. Don’t have an issue running them on our club layout and our switches are Ross.
But…. the couplers tend to open with the weight of 9 cars together behind a scale GG1. I cable-tied each coupler shut and no more uncoupling.
Anyway, for $25 a car, we’ll worth the small mod on them.

I have a set of Williams and MTH heavyweights and the trucks and rollers are horrible. I know I will need to replace them. Thank you for the insights.

Hey Ben,

How far back do those Heavyweights go as far as a date? I have 6 Heavyweights brand new in a box, unused yet, need people & lighting. Have LED's on a tape roll and some of GRJ's voltage/rectifier boards for the lighting purpose. Will have to check out the trucks on these. Hobby Shop in Somerville, N.J. was closing it's doors and the owner sold me 6 pasenger cars, still in a sealed box, for $200.00. Glad you brought this up!

I believe that due to this shorting issue, many of the heavyweight passenger cars were part of a safety recall. Check this link.

I am going to guess the ones in the yellow and black boxes are OK. The earlier ones in the black with gold lettering may be the ones to check.

That's the style of the Southern Pacific set I have. I'll have to look at my cars again. Currently have no issues with them. Although, I did rewire the trucks and interior lighting.

First, Ben, nice work figuring out how to fix those cars.

Thanks, milnyc, for posting this link!

Second, how did a CPSC recall get put into play? Was there a fire caused by these cars? Did MDK realize they were a fire hazard? And, how much $$$ did this product recall cost K-Line?

Mark,

First of all the recall, and most likely the truck issues mentioned by the OP, are only problems associated with K-Line's first generation of scale heavyweights, which was labelled "The Heavyweights" by K-Line's marketing folks at the time.  You'll find that term prominently displayed on the packaging.  They did not extend to any of the more recent heavyweight passenger cars K-Line produced.

At the time these cars were so much more detailed than anything that came before them, and of course were in scale length which was also novel, so I immediately bought a set (NY Pacemaker, K71-4907-5) as soon as they were introduced.

Within a short period of time it became apparent that the wiring, as installed from the factory, was quite a bit shorter than it should have been, restricting pivoting of the truck and eventually causing wear-through on the insulation where it passed through to the interior of the car.  There were also apparently issues with a spring configuration on the pickup assembly.

If I remember correctly this is why the recall occurred.  Sparks and smoke.

The things one can learn here are endless. Found this post and pulled out my LIRR set from 2000. Sure enough, the rollers contact the axles when depressed fully. I never had the problem due to no switches on my old Christmas layout, but with my in-construction layout there will be 16 Ross switches. So, this discovery is timely in that it saves me the grief of figuring it out. BTW- yellow and black boxes. Thanks to all!

K line heavyweight trucks also  had a zinc pest problem.

FWIW here is my simple fix.

Later K-Line heavyweights might have but not "The Heavyweights" line as far as I can tell.  Because they were so popular there are many, many, many of these out there.  You can find them everywhere, eBay, shows, auctions.  I run across many of these over the years and have never seen any with zinc pest, or any reference to zinc pest in them.

I have a set of K-Line Long Island Rail Road blue "Cannonball Express - Dashing Dan" heavyweight passenger cars that have been on my layout since I bought them (new) years ago. Have never had a problem but I don't run them very often. The pickup rollers do contact the axle if pushed far enough. I don't see an easy way to make a proper repair so I won't run them any more and will instead run my well made MTH 18-inch LIRR "Madison" cars on which the pickup rollers cannot come in contact with the axles. Thanks for pointing out this problem.

I have 3 sets.  All came in dark boxes as i recall .  About half of them had the trucks fall apart

That was a great price on those   

The cars I converted are the second run Heavyweights   They had interiors with no people   They were in the Black and yellow box The first six car set is K-44382  The Lackawanna Limited 6-Car Set These came out in 1999 with the F3 A-B-A   They look a lot better with the LED's   I also used one from Rays Trains for the Observation with the Tomar marker lights and the drumhead

The second set I converted were all custom painted in Erie   I believe they were NYC green to start   They were also a mix of first and second runs    The baggage car had fixed doors so that was a first run   The diner and two coaches were second run with interiors    Each coach had a different type truck on it     Not sure of the timeline on these   

The first release were in the black box with silhouettes in the window.   Those are the ones that were recalled

That was 1996 and the first run of these cars   They didnt have interiors  Mine came out in 1999

The cause of the recall on the K -Line Heavyweights was due to a lack of electrical isolation with the coupler assembly. One of my Ringling Bros. Circus cars derailed while my young daughter was playing with it. The derailment caused a short, this short sent voltage from my ZW through the metal frame and the all metal coupler assembly. The centering spring of the coupler assembly turned cherry red from the voltage and caused the cotton snow mat under the track to catch fire. When I returned to “fix” the train for my daughter I had an open flame under a live Christmas tree! I contacted K-Line, Classic Toy Trains, and the govt consumer office at that time, the same day. The gov’t issued a recall, the repair was to replace the washer that the centering spring rested on with a fiber one thereby breaking the circuit. The recall had nothing to do with wiring of the roller pickup. I strongly recommend anyone using K-Line “heavyweight” passenger cars check the truck-coupler assembly to ensure there is electrical isolation. This is at least the third time I’m responding to incorrect speculation as to why the recall took place, if you don’t have specific knowledge of the recall keep your opinions to yourself. I’m sure there are still many cars that didn’t have the fiber washers added, these cars could still be a fire hazard if not under adult supervision.

GRJ, Darrell, N&WY6b...

In post 6 the author offered that the recall was likely due to the roller shorting problem. Of course, it wasn’t, but if someone took that at face value without looking further they might believe that if they have the later roller frame or if they have insulated the axle they are now safe. That wouldn’t have any effect on the spring issue in the recall, would it? So they now have a false sense of security that things are fine because they read here that the (implied) solution is newer roller frames or insulting the axle while the original recall issue may still be sitting in the couplers.

MHM tried to set that straight. Trainstr is correct that if you aren’t sure about something, don’t offer an explanation for it, and I would add, particularly so if it’s safety related. It could have have been more gentle, but it was still correct, because once you’ve read it on the Internet it has to be true...

The recall in 1996 had nothing to do with the problem I described in my OP   The fix for the problem in the recall was to place fiber washers on either side of the coupler spring to prevent it from heating up with a short on the track   The fiber washers isolate the spring from electrical contact    The shorts I described in my posts are momentary    They are on cars that came out in 1999 and they already have the fiber washers on the coupler spring.    Nothing heats up   It just trips either the transformer or in  my case the PSX  and then recovers   The liquid electrical tape or tape on the axel seems to prevent my problem 

There is an easy check for the coupler spring recall   Pop the c clip on the coupler arm and insure there are fiber insulator washers on either side of the spring as that is what heats up.

Don’t really matter what the short is, a ZW will go into arc welding mode with out some basic mods,….also agree with John, ….who gave you the in charge card?…you don’t like the opinions, you’re free to move on,……

y’all are making mountains out of mole hills, ….again,….wrap tape around the offending axle, and the problem with the roller touching the axle is solved,…..

Pat

I’m guessing the reason K-Line trucks are notorious for sagging springs on their passenger trucks with pickups, is that the roller spring is not isolated from the circuit, and being continuously exposed to voltage from the track, is the same reason Trainmstr experienced a BBQ’d passenger car?

I still have one unrun set of preSandy K-Line 15” aluminum passenger cars. I’ll assume they weren’t affected?

Jeez

First off it’s not a case of not liking an opinion voiced here, I read opinions I don’t agree with everyday on this site and don’t say anything. It’s about a safety issue. You all sometimes forget we have newbies visiting this site for information, the last thing we should be doing is forwarding a false safety narrative. I’d like to hear how many of you were even aware of the recall and what the facts are. Imagine a young father goes to a garage sale or train meet and buys his child some trains, in that sale are some heavyweights, he knows nothing about fast acting breakers or the need for them. Can’t you all see the potential for a serious issue? Maybe your years in the hobby are clouding your judgement. Could I have worded my response differently? Yes. If me wanting this site to provide accurate information to everyone is being “King for a day” so be it.

John, I didn't admonish you for posting false information, I referred to the specific post which contained "I believe that due to this shorting issue, many of the heavyweight passenger cars were part of a safety recall. " I even gave the #. I simply thought the reaction to a snippy post was even more of the same. I pointed out that MHM's post corrected it.

Ben's post also let people who didn't bother to dig into the recall info know that the roller issue wasn't the recall issue. As far as Ben's post after mine, in the future I promise to try to predict what might be posted some time after I do so I can properly adjust my post to reflect that future event to calm everyone.

I've only been here a couple of years, but I've seen way too much of this.

I just had the same problem with one of my DM&IR cabooses that I recently got. Noticed arcing and shorting out the track. Finally caught what was going on. If you look real close you can see some etching on the roller and axle. I added some oil to the springs and right now anyway, I did not get the arcing. What type of tape did you use for your fix?

It's a shame when a post becomes an argument.

It's even more a shame when a safety-related post becomes an argument.

I'm going to be blunt.

A fire, a real fire with flames, is a life-threatening situation.  The facts are important and deserve to be shared so that none of us ever see such an event on our layouts, or in our homes.  Remember that our stuff is capable of starting such a fire.

Now, here's the problem.  The internet is full of bogus banter, too much of it emotionally charged, rather than based on facts.

Do we have to worry about this here, on the OGR forum.  Yes, unfortunately.  It's everywhere.

Our best option to circumnavigate this is to stick to the technical facts, especially on this topic of safety.

On the flip side when you cite technical facts please be aware that you might be challenged, which is not only to be expected but to be encouraged.  We deserve verified facts.

Ask yourself this before you post: Where did my facts come from?  Are they based on true verifiable events, data, and conclusions, or instead on emotions?

Please check your emotions at the door.

Presently, based on the raw emotion seen in this thread, I'll stick to the text in the recall issued by the CPSC for my facts.

Let's lighten up a bit, OK?

Age and manufacturer are irrelevant in this hobby, old trains and manufacturers long gone are operated on layouts every day.

As MHM said: See CPSC Release 97-053 dated 12-24-1996. If I knew how to attach it from my phone I would, maybe someone else will attach it. It was also published in CTT sometime in spring of 97. The CPSC is specific in saying to not use the cars until corrected.

In the release it says K-Line estimated 20,000 units were effected. That’s a large number in a small hobby.

My LIRR set, as delivered new from Nassau Hobby in 2000, has clear plastic washers above and below the coupler pin spring. K4439A. I had never heard of this recall, but it seems my set had the fix from the factory in China. Roller still does touch the axles. Kapton tape on order.

I ordered some Kapton tape too.

First we’re talking about an 8 yr old playing with trains under the tree, something that has been repeated hundreds if not thousands of times, continues today, and hopefully continues for decades into the future. When this occurred in 1995 the ZW was a perfectly functioning transformer with a properly functioning overload breaker. In all the derailments my 3 children and myself have had, up until that point (I’ve been collecting trains since 1954), with any other manufacturers trains and this particular transformer, did a condition occur that created so much heat to cause something to combust. In addition, this same ZW never failed to trip with any Lionel, MTH, or newer K-Line cars before and after that recall event occurred.

I for the life of me don’t understand why any of you would want to question or downplay a national safety recall. Obviously K-Line agreed it was an issue otherwise they wouldn’t have come up with a fix in just a few weeks after my initial contact with them. If you doubt this issue exists, which based on responses many of you do, take a heavyweight, remove the fiber/plastic washers from both sides of the centering spring, apply power, create a short, and bask in the glow of a cherry red spring. As for the transformer, ZWs will continue to be used and a majority of them will never be modified with new breakers because people just don’t know nor are there readily available services to modify them. Do you really think a newbie or seasonal hobbyist knows that a ZW and a wire coat hanger can weld?

We all need to be ambassadors for our hobby, sometimes that means looking at things with fresh eyes not with dozens of years of experience, providing ACCURATE information to anyone seeking to enter this hobby or it will indeed die, that includes communicating the bad with the good.

Recall Details

Hang it up!

OK guys....settled down a little and take a deep breath. 

It sounds like there's 2 issues here. The roller shorting out on the axle, and the antique transformer not cutting the power in time.

Once again when there's smoke,and or fire there's a "cool affordable classic transformer"lurking in the background of the layout.

Either add a fast acting fuse, or switch to a modern transformer. They had cloth covered extension cords and Christmas lights back in the 40's and 50"s too. You wouldn't dare use them today.

Last weekend I put my K Line 28th Anniversary heavyweights on the layout. After reading this thread, I looked at the trucks and found all the coupler springs have plastic washers. However, all the pickup rollers, if pressed at the correct angle, will contact the axles. Before running them anymore, I will put tape on the axles, and will also inspect all my other K Line heavyweights and correct these issues if needed before running them again.

Thanks Ben for posting this.

Hey Ben,

Those Heavyweights that I bought from the hobby shop, now out of business, are the same # as yours. Yeah! I like Lackawanna too. Anybody who might have lived in Montclair, N.J., knows that Lackawanna R.R. had a terminal, at Grove St. & Bloomfield Ave. (If I remember right) My stomping grounds as a young shaver, grew up on Glenridge Ave. There was a walk crossover beginning/ending at Pine St. to Bloomfield Ave. in Montclair (now gone). Back in the 50's, Pine St. dead ended at the corner of Pine St. & Glenridge Ave. but with all the changes (tracks gone to the terminal, new apartments, Pine St. extended to Bloomfield Ave. with the crossover gone). The N.J. Transit R.R. Co. took over the R.O.W. of Erie ( back then) up by Pine St., brought the tracks through Sherman St. & Bay St.( station was placed there also at Bay St.) and reconnected around Bloomfield Ave. to Lackawanna R.R. R.O.W. The trains were MU's back in the 50's and as a kid they really fascinated me, especially the signals. I believe I heard as a youngster that the trains in Montclairs terminal were known as the "Millionaires Express" since there were a lot of Wall Streeters who lived in Upper Montclair. Naturally we were considered "to be from the other side of the tracks" and I believe there is still catenary there, just newer catenary.

Anyway, I'm glad everyone chimed in on this topic to help out others and I gained a lot. I'm also glad that the 8 year old child is o.k. Hopefully the joy of running trains is long term.

I Googled: "How long does it take a ZW transformer breaker to trip when shorted". Feb. 16, 2017- The Lionel Test specs for the ZW transformer is that it should put out 30 amps for 11 to 40 seconds before the breaker trips. Wow! I never knew that! I heard from a Lionel service station guy named Jay, that he had told me it could take up to 23 seconds. I never doubted him, but never knew that this transformer could put out 30 amps! That is dangerous! Although being with the N.J. Hi-Railers and The Raritan Valley Hi-Railers (Modular), we always used PSX circuit breakers (both groups). In the Raritan Gang we used the old ZW's along with the PSX and I backed up the protection with a fuse since this was the original safety at 10 or 15 amps, in series with the PSX, just in case the PSX failed. You never know! Before the PSX's we only used the fuses and I can tell you when the 15 amp fuse blew because of a derailment, you can hear it across the layout plus the train came to an abrupt stop! All in all, consider putting a fuse (fuses were before circuit breakers and they did the job in homes as long as one didn't try to "modify" the fuse-larger or putting coins into the socket for what the circuit was rated by the wire size [yeah as an electrician, you wouldn't believe how creative people can be]  into your center rail line if you want to use the old ZW. The size of the fuse is something for the operator to figure out because the loads will be different from train to train. I suggest a 10 amp or slightly smaller, to start with, unless you have an ammeter to measure the amps. Check out all of the Googled info about the ZW.

I have a friend who, on one of his older postwar-style layouts, had a double-track arrangement that looped across itself at one end with a double-track 90-degree crossing. One leg of this crossing led into a wide uphill 072 curve that led up to an upper level. Because trains ascending the grade needed additional voltage, this segment was isolated and fed from another set of terminals on the ZW feeding it higher voltage.

He tells me during one run session, a train pulled by a MTH Proto-1 locomotive experienced a derailment in the loop that caused the loco to stop across the two power districts. Full grade-climbing voltage was now running into one end of the locomotive through its wiring and out into a short circuit. As he was moving to his control panel to shut off the power (duckunders had to be navigated to do this) , the stopped loco, which did not have a smoke unit, suddenly started doing an impromptu imitation of a smoker .

By the time he was able to lift the errant loco off the rails, most of the internal wiring's insulation was quite thoroughly roasted. The ZW took its sweet time tripping, presumably because the one axle that derailed didn't present enough of an amperage draw to trip the breaker. He was able to  replace the ruined wires one by one and at the end, the unit came back to life (also subsequently passed inspection by an MTH tech)

In a similar vein, I had one of those first-gen K-Line F3's (the six-motored KCC C&O) derail on another friend's ZW-powered layout. This incident managed to roast the coil spring inside the T-bar coupler on the leading A unit. I only noticed this after I ran the set at home and noticed the front coupler would no longer open. When I took it out to check the mechanism the spring literally crumbled. Must've gotten pretty hot to do that. That wire certainly wasn't large enough for the ZW pumping current through it to sense a short. While I never saw the thing glowing, I imagine it would have to have gotten pretty hot to damage the spring to that extent. I later replaced it with a spring cut from a retractable ballpoint pen.

ZWs, KWs and probably some other "toy train transformers" weren't and aren't very toylike.

My PH180 bricks trip on any short, and I'm sure they'd trip in a flash for those K-Line cars.

While the PH 180’s enjoy a reputation for having fast circuit breakers, what about the PH 135’s? Do they have the same or equally fast breakers? While running no more than two trains at a time, my PH 135's breaker has seemed instantaneous with the very rare derailments that have occurred.

No, the PH135 have ordinary thermal circuit breakers.  They're not terrible, but nothing like the PH180 electronic circuit breaker.

Still have the fibre washers in the envelope sent to me by k-line.  There were no instructions so I never installed them.  After reading the above posts, I now know how to fix the cars. 

Thx guys.

Kapton tape arrived and applied today. Now the next job is to reseat all the figures that are flopping around loose inside the cars. Planning on using that snot that the mailers have to hold the pages closed. Its available online.

Do you have a source?  That sounds like a worthwhile experiment, I'm currently using hot-glue, but I think that stuff might work better.

Google "booger glue", "fugitive glue", "gummy glue", and shop removable credit card glue. Its everywhere.

The plot thickens, finally got around to adding the washers received in 2000.  Cars may have been run once since owned.  Found out that two of the cars have updated trucks with a plastic strut added to prevent the roller from contacting the axle along with a plastic coupler arm which isolates the spring from the car chassis. (See pics.) Verified with an ohmmeter.  So two cars don't require the washers and two do having a metal coupler arm.

Since I'm working on the cars, the hot wire to the bulbs will be interconnected to minimize blinking.

As a consequence, I have 4 unneeded washers, free to a new home.  E-mail is in my profile.

For reference, the washers measure 0.380 od, 0.180 id, 0.009 thk.

Good info. I have a few of the K-Line heavyweights and one of mine is on the list. I never heard of this issue or recall.
