I have an even better idea: how about drivers get their eyes off of their electronic toys' screens and actually look at the roads they are driving on. Anybody who cannot see a RR crossing (irrespective of signage) is too blind to drive, and any truck driver who cannot tell that the crossing is going to cause the rig problems shouldn't have a CDL.

While I think it's a good idea for the maps to always have as much information as possible, I also agree with Palallin above. Some common sense needs to be used when driving and you need to be aware of your surroundings no matter what your app or map or whatever is saying. Also the roads and other things change and the maps lag behind the changes being made. I don't think they are never completely up to date to match actual conditions.

Honestly, I agree with you fellas -- drivers need to pay attention. But then I still physically stop at RR crossings and actually turn my neck to look both ways. (Safety Bonus: you get see some great rollng stock that way :-). And the stories/complaints that I hear from friends about using their digital navigation systems have never inspired confidence in the data nor in peoples' ability to drive undistracted using these systems.

While l am old-fashioned and use maps to get around, with general success, once l used a friend's GPS to try find a Menard's in southern Ind. It led me on convoluted circle tour among assorted side streets, for a store right off the interstate. I was not inpressed. I recommend your mother's admonition to look both ways before crossing the street (tracks).

So why doesn't Congress just get off its butt and just mandate man-rated software (that cannot be hacked), mil spec GPS systems (that cannot be stolen for nefarious purposes), and non-hackable networks that tie it all together? If you're going to add this kind of information to mapping systems, all the components better be dead-on accurate. My GPS is accurate to 10 meters - that's 2 lanes on the highway. To me, that's not good enough. As an aside, how does PTC know which track a train is on,...

Please let us know how your troubleshooting progresses. We had a prewar 30 degree crossing at the TTOS mall layout years ago. It was American Flyer O gauge and the center diamond was a huge piece of phenolic. It was so big in fact that what ever roller was crossing it would be dead for too long of a time, causing the occasional stoppage of the train. We ended up putting a diamond of sheet metal on top of it connected to the center rail.

Hi TRR, I looked at the track plan and see the curved approach to the 90° cross. The SD-70 has two collectors that appear to provide sufficient spacing to compensate for the hot or the wheels being insulated momentarily. I have not had one in my hands, so I don't know what MTH does underneath electrically in their cross. Would you post a photo of the bottom? You may have to solder some jumpers to provide connectivity through the cross. The other setup I don't like about MTH RealTrax is that...

Hi RoyBoy and Carl, Thanks for your suggestions. Last night as I was shutting the track down I was thinking I may need to add a wire somewhere but hadn't figured out how to handle the perpendicular connection requirements. A diamond shape on top is a great solution and one that might be easy to test. I'm off to work but will disassemble, explore, and photograph the underside tomorrow when there's better light than when I get home. I did not know about only one common being connected In MTH...

Moonman/Carl, #1 Thanks for looking at the underside of the cross, the suggestion for protecting the jumper (it's on a carpet in the living room), and a possible reworked track to fix the curve problem. The MTH RailKing SD70ACe is a PS3, item number 30-4231-1E that came with a RTR set. I think the problem is that the rear roller is dropping off the center rail at the exact moment the front one is on the plastic as shown in the side view photo reenactment. It only happens at slow speeds.

Ah, I get it now, thanks, and I reread your earlier post and it makes sense, too. It's rather late, so what I did to quickly test your solution was to prop the track sections above the Y up off the floor a little bit. Doing so created a small gap between the sections. I turned on the track power, flipped the remote switch, and sure enough, it worked like a charm! Tomorrow I'll get the files out and fix it permanently. Probably a red herring, but with no power to the track, if I use my finger...

First never use steel wool around toy trains it gets tangled in their guts. I'll say that before something breaks, I learned that from some who killed an engine with it. I have a similar issue with the Lionel fas-track version of the 90 degree crossing, and derailment issues with manual O-36 switches.

On one set of MTH roller center rail pickups I found the stamped metal frame that holds the rollers was not free to move. I had to "adjust" it with pliers until it would move up and down freely. Just another MTH quality issue. I think Lionel has the same problem since they both are Chinese products. But we could not afford them if they were made in America thanks to the high cost of labor here. I guess we can't win. LDBennett

I just filed the rail as LDBennett suggested to isolate the switch. It was a little tricky to get at the base of the rail because of the plastic tab. So, I added a tiny piece of electrical tape at the base of the rail. Maybe there's a better way (Dremel tool?) but all I have are mini-files. The triangular ones work well for filing track because they are stiff. Here are pictures for future reference. Thanks again everyone. Tomlinson Run Railroad

I used a Dremel with a narrow disk to reach all the way to the plastic ties. I had to mod all seven of my switches this way. Another MTH quality control issue for me. I would add that those short sections of track are controlled by the position of the points (that control the direction the train will go) through linkages internal to the switch. That linkage changes micro-switches to change the electrical state of those two anti-derailment rail segments. They become just an electrical...

Recap: the inside switch at the bottom of this layout makes a buzzing sound if you try to switch it either manually or with the remote when the track has power. Its position cannot be changed. It only buzzes it you try to switch it. And, previously, if you added power to the switch by itself outside of a layout, everything worked fine. (I didn't retest that this time.) I bought a multimeter today and did some simple testing. Perhaps this new data will explain to one of you what's going on...

TomlinsonRunRR : I did a poor job of explaining the anti-derailing problem.Since I am not able to post a picture, for whatever reason, I'll try explaining it a bit differently this time. Imagine the switch is a "Y". The track rails that need to be isolated from the adjacent track section correspond to the inside of top of the "Y". I am not talking about the points but the two fixed rails on the inside. They must not touch the rails of the track section next to the switch. There needs to be a...

TRRR, The 90° cross looks ok electrically. All of the rails around the center block are connected. The jumper is there to provide the option to isolate the pieces of the cross if there are two different power districts crossing one another. The jumper should be there for the configuration that you are using. One caution, move the jumper so that it doesn't lay across the common contacts to avoid chafing the wire and having a short. A 3 axle truck on a small radius track looks like a tight...

TomlinsonRunRR : I had a similar problem (buzzing switch motor). The anti-derailment feature of MTH switches uses the inside rail on both the straight and curved sections down from the frog as an electrical switch to detect a train when the switch is set the wrong way. The farthest most end of both those short rails that form a "V" in the switch need to NOT touch the adjacent track section rails. That is they should be electrically isolated. MTH makes those track too long and they can touch...

Some of the less expensive RailKing uinit have this also. I have a pair of early 90's Weaver locos that lose power by being on a switch gap and a UCS gap at the same time, but am not aware of any double rollers being available. Woerkaround is not to go too slow, and PS2 keeps on going.

Problem #2 I added a picture in the post above of the new track configuration that is similar to what scottransam/his dad had success with.

I have the same layout and have found that the turn out can not be placed directly connected to the 90 degree cross so I moved it back by one 031 curve to your left and the problem was solved. My sd 70 must have just enough of a pick up roller spacing to not make contact when going thru the curve and turn out together. For what its worth my dad had the very same problem and he fixed it by moving the turn out one track piece back from crossing.

Tomlinson, specifically both rollers are supplying power to the engine full time and have no relation to what direction the engine is traveling. Actually the main purpose of having two sets of rollers is to bridge gaps where there is no power so the engine will keep going. It is possible on some switches (crossovers) for both rollers to be on a dead spot however. This problem has lessened by some more expensive engines having two double rollers, i.e. there are four rollers on the track. Dennis

TRRR, It seems the questions have been answered about the rollers (collectors) for the center rail. I like the track change idea. No, not another transformer, just another connection with a lock-on on the inside loop and opposite of the other. That will provide better track power distribution and connect the other outside rail if you place it opposite. Lets leave the Lionel engine issue and the switch operation issue aside until you get the SD70 running correctly.

I am not a fan of MTH Realtrax even though my 7 x 9 layout uses it almost exclusively. I have a MTH City of Denver tin plate train that will not go through an O-31 switch without shorting out the track due to single powered truck of the engine and unique design of the center rail pickups. I can not run that train on my layout. All the switches have guide rails that are so sloppy that the truck wheels can move such that they bump into the plastic frog. It is not enough to derail but makes a...

In case anyone ever stumbles on this old topic, here's an update. After running my trains over the MTH 90 degree cross for about four months, the raised plastic that originally seemed about 1/32 of an inch too high is now completely and uniformly worn down. Now I can run my MTH engine over it at the slowest possible speed and it no longer stops. Yeah! Problem solved. Tomlinson Run Railroad

Bob, The track actually goes into the next room where I plan to build a short staging section about 8 feet long. The layout is a 3'x19' shelf switching layout. The staging will allow me to build a short consist that will enter through the "tunnel" to be switched. Once I eventually build all my industries, I will have up to 18 places to spot cars.
