Does anyone know if this paint scheme is correct with silver trucks as shown? Or should the trucks be gray? Thanks!

Good affordable pullers

Blick Fang ·
Hi I have been using a Williams GP9 for 20 years and it always pulls a dozen modern cars with no problem. I am looking to get a replacement for it. As you probably know, Williams stuff isn't as readily available as it has been. Railking seems a bit pricey. Does Lionel have any low detail, good affordable pullers? I always think of Lionel magnetraction which I am not interested in. Looking for a GP something. Thanks!

Sunset 3rd Rail GP9/GP7

prrjim ·
I would really like to see Sunset 3rd Rail do a GP9 and GP7 with their great single motor drive and nice QSI sound much like the recent SD7/SD9. There were 3466 GP9s and 2617 GP7s built in the USA plus some in Canada for most major and mine RRs in the country. No one has done a good model of these with road specific details and good single motor drive in many years. The 3 rail mfgs have done some but these sit too high, have too wide trucks, 2-motor jerky drives, and with generic details,...

Lionel Legacy GP9 shell on a GP7 frame

Doug Kinsman ·
Hi everyone, just wondering if a shell from a GP9 (38878) will plop onto a GP7 (28592) frame? In that same vein, does the November Lionel parts sale typically include shells? That B&M looks sharp and I already have the GP7. Thanks

That is a good looking set of engines...I assume you are not running in Command?? Taking either motor out and you won't have a way to mount the truck to the frame. Getting rid of all the plastic gears is a good way to go. I use the metal post war set up. Are all programed the same number. If you want the rear engine facing the opposite way of the lead engine, you can get the rear going the way you want and lock it out with the program switch. Marty

Thank you for responding. The units are a nice addition to my layout. I must say would rather have two motors in one unit though instead of two one motored units. You are correct, I don't use command. I don,t even have the device to use it. Now that you mention taking out a motor would leave me without an installable truck. As a matter of fact, the powered unit would not have any railsounds if it had two motors as the railsounds truck is different. I guess I could put one tailwinds truck in...

What I have to say about these engines isn't good. I have a set of these same B&M GP9's purchased used about 6 years ago. I had the same issue with stripped gears, replaced them with metal and they still stripped. I've also had electronic issues with them including suddenly reversing direction when passing through switches. Frankly, I have concluded these engines are junk and not the best purchase I ever made. On the extremely rare occasions I run these now I do so using a single engine...

Thank you for your response. Is there a way I can lock the engines in one direction without command? It sucks that Lionel would make suck a flawed product. The sound boards have what I would describe as a white, moldy substance on them. I don't dare clean the boards either. Those gears cannot be stripping from normal wear. It must be because one unit goes into reverse...maybe after I blow the horn in quick succession. Please tell me how to lock the direction, hopefully without command, and I...

Re: Lionel GP9 Lashup Issues, Need Your Help

Unfortunately, I don't believe there is a way to lock these in a direction by conventional means. You have to use TMCC to do so. I suppose it could also be done using Legacy. I think the stripping has something to do with the angle at which the motor sets in the truck. I recollect reading something in the past that some Lionel engines had this problem and there was a way to shim the motor enough to prevent the gear from stripping. Someone more knowledgeable than I would have to explain that...

Thank you. I found you prior post response regarding stripped years. You said greasing is key. I bet that I had not put lube on the new metal gears when they were replaced. You mentioned using a worm gear. Is that different than normal replacement metal gears? Thanks.

The engines can be locked in a different direction, get engine moving in the correct direction and flip the run program switch to program, this is your eunit lock out switch...You can not mount two motors in these because the AC motors are too wide. That is why the one motor sits up in the cab area... Marty

I don't have enough knowledge about running TMCC engines in conventional mode to be of much help. However, I have seen this set being run in a TMCC environment, and the operator wasn't having any problems with it. Lionel did these 3-engine sets in B&M, Wabash, and Florida East Coast liveries. Maybe there were some issues, but I've never heard any reports of this. The reverse pulling you have must be quite severe to strip gears like that. I have quite a few of these Lionel Geeps from the...

I want to thank everyone for their input. I truly appreciate it. I know more on the matter than I did before. I try to research a product online before buying, especially model trains that can be quite pricey. Nothing came up that these lashups were junk before I bought it.

OK. I. not done with this lashup yet, although it is for sale if someone wants it!!! I noticed on one Lionel GP9 there are two truck-mounted can motors and the base frame has the same or a similar + markings on it. For those who tinker with setups out there, I have some questions: 1) Are all Lionel GP9/GP7 shells have the screw holes in the same location so they are interchangeable? If #1 is a yes, then I should be able to transfer the Boston and Maine shell with the strobe light to the two...

On those engines I believe the frame mounting holes are on the bottom of the shell on the inside. Not sure if the two can motor is the same set up, you will have to turn it over and check it out.... Marty

Thanks for the info. I actually pulled apart an RS3 that I have. Other than a different truck style, the can motor set up is virtually identical to the GP9 with can motors. However, the motorized GP9 I have has different wires coming from the existing motor to the sound board. There is a lot attached to the boards in the units. I know they communicate with one another. I guess changing everything around was wishful thinking. I'm good with general electrics but I am by no means a certified...

Re: Diesel Sound Issues

BobbyD ·
Been a long while since I've touched one of these. Because the Lionel transformer adds positive DC to the AC wave for the horn/whistle and the button will add negative DC for activating the bell sound. Reversing it will do the opposite. Don't think it raises the voltage though.

The 1033 could have an issue with it's whistle circuit. Of course, you could also have the transformer connections reversed, did you try swapping the polarity of the track connections.

Swapping the polarity did the trick! Not exactly excited about the horn quality. I'd like to get my hands on a 5904 or 5906 to see if I like that versus the transformer controls. Any advantages / disadvantages?

Well, the horn will still sound the same.

Re: Diesel Sound Issues

John Fuller ·
No doubt... problem solved and thanks again for the help. Doing some reading - looks like all the 5904 does is controls the polarity of the transformer controls - ie: one setting for horn, the other setting for bell. Switch the leads and it does the opposite. You still need the transformer to turn on the horn. The 5906 can accomplish the same thing with two but actually has a button to activate. Am I reading this right? Thanks again!

Looks like the 5904 was a specialty item that was just used with a specific transformer according to this document. I truthfully never used either of these units. Operating Instructions Boxcar with RailSounds

the issue is not with the P&D drive parts, but the original Weaver sprockets. the acetal sprocket material was not aged and would split. if you don't have confidence in the P&D sprockets (I have had no problems with them over many years), you can also order them from Sterling Instruments.

Re: P&D GP9 Drive Problems

My experience has also been that the original Weaver gears and sprockets were prone to cracking. P&D has replaced the original weaver parts in their drives. Also replacements I got direct from weaver when they still serviced them worked out fine. That being said, you still might get a cracked gear or sprocket at some point. Or some other part. But the beauty of these drives is that yes you can do all the repairs and rebuilds yourself with a few hand tools and some patience. You do not...

I used NWSL wheel set, and they are working perfect, beside the brass bushing included. Regarding the Fine scale 360 IMO is a big plus, because the chain links are, in some case not enough to adjust it properly so the chain will be too tight or too lose. my 2 cents. Andre.

There's a lot of good info about this here: https://bobsobol.smugmug.com/T...PD-Drive-Train-Work/ I have shamelessly copied everything I learned there and from several threads on here with MaxSouthOz and others and it works great with the Finescale 360 chassis and drive upgrades. I recently added a Maxon coreless motor, Loksound Select HO decoder and Tang Band speaker to the upgrades on an RC GP9. My best running and sounding loco so far!

According to another post here on the forum, the Atlas gp9 frame will also work for this kit. It stands to reason, as Atlas bought the Red Caboose tooling. The Atlas frame shows in stock now at $14.95 each, although it does not include the pilots. I can't speak to amending or attaching original drive components to the Atlas frame. That may be more trouble than it's worth. Atlas gp9 sill unit Jim

As for the metal lathe I used, if you stick to P&D replacement parts you can do everything with just hand tools. I wanted to change the sprocket ratio for slower speed running. That helped when I used non-back EMF decoders. These days the motor control in the Loksound L is so good I won't change any more drives. The original drive ratio also produces less chain noise. Because acetyl shrinks over time, there have been outbreaks of cracked gears in many vendor's products, even in certain...

I looked at the Atlas frame on line in the parts list. Based on the drawing, it does not look like the P&D conversion will be a drop in. I think you will have to drill and tap the aluminum frame to install truck bolsters. You have to cut and drill the original IM frame for this also. And it looks to me like the pilots and steps install totally differently on the Atlas. On the IM unit the pilot/step assembly is part of the shell and wold have to be cut off. On the Atlas it looks they are...

Hello Patrick. I certainly would be interested in what you may have. I have three Red Caboose kits (2 full kits and 1 body kit). I am going to convert the two powered units to DCC (dead rail I think at this point) using Loksound Decoders, Des Plains Hobbies frames and P&D drives (none of which I have purchased yet). My first attempt at DCC and first attempt with Dead Rail. Sincerely, Stephen Wilson

Bob, I took your recommendation and used the T1-1925S. Cut off the end tabs and fixed it on some side plate "legs" behind the motor and above the drive. I 3M taped them to the sides of the Finescale 360 weights. It just fits but I had to shave the inside edges of the plastic frame/walkway piece that sits on the metal chassis slightly to get the body on. Excuse the spaghetti wiring, still in test phase, honest... I am continually amazed and inspired by what you and your colleagues are doing...

Also the shafts have to be sleeved out from 3mm to ~4mm for Weaver/P&D drive. I've bought 4 so far, all work great.

I may be in left field here but the can motors are DC and if I'm correct you have Pul-mor motors which are AC so you probably have different electronics in the engine itself. Now with that said if your just swapping shells as long as they are both GP-7/9's you should be okay unless you go back to post war engines where they mounted thru the noses.

Lionel made a number of traditional GP-9s with twin can motors. Only about 4 of them, though, all Chinese production. I have the C&O version, which came with a set, and plan to use it with another shell. There were three different shell mounting types going back to the 1970s MPC days, but your B&M engines have the most recent 4-screw type, with the screws going in from the bottom of each corner of the chassis into plastic shafts coming down from the shell. The twin can motored...

Thanks for the info everyone. I contacted the motor doctor and there may be an issue with one or both motors as they are built to spec and should perform the same. I will see what he has to say and if I want to fix at that point. I will post an update in a few weeks.

Here's how I fix them.... Mechanisms for Red Caboose GP-9s. P&D brass trucks and Des Plaines brass frames. As usual, Faulhaber gear head motors with everything turning 1:1 in ball bearings and wipers mounted in Delrin. Decoder is LokSound. They are new to me but from my limited knowledge they seem really good. One down, two to go. Two are P48, one is regular O Scale. Wheels spinning and maximum voltage (13.5 volts) draws .22 amps. My Pittman gear heads can't do it, plus they won't fit.

Nice work Jay! What's your overall gear ratio (motor to the wheels), and top speed running light at 13.5 volts? Thanks!!

Re: P&D GP9 Drive Problems

Jay C ·
Hey Ted, I was hoping nobody would ask! Actually, I haven't figured it out yet. The gear head motor is 14:1 The motor tower is 1:.82 The truck towers are 1.5:1 Top speed hasn't be computed yet. I just knew this set of ratios gave nice slow to medium speed for switching or yard work. Ball park 30 to 35 mph. If the customer wants to speed things up a bit we just change the upper pulleys and belts of the truck towers. Jay

How you attach the acetyl blocks is obvious. Your photos are quite helpful for that. Not so obvious is the shape and mounting of the wipers to the acetyl, and if the wipers are shaped with tabs or other details, how they are made/procured. Bob S
