Friends that work at another vendor of N scale locomotives tell me that the #1 cause of warranty repairs was the misalignment of the truck contacts with the pickup strips. The expert modelers here may never have this problem, as they know how to fix it, but perhaps its a source of frustration for the newer modelers who want the locomotive to run out of the box with no issues.If you were in charge of the product line, what would you do?Bill Kepner
Not to argue this one way or another, but I’ve *never* had a wire connection fail. Not once. Am I just lucky? Does that happen a lot, occasionally, sometimes? Is it about bad solder joints, or wire eventually twisting and breaking off? Is it actually a serious issue? Or a potential problem...?I’m not being flip, this is straightforward question. I do know I’ve had connectivity problems on some wireless contacts, especially with sound. But I do like the freedom to pop the trucks off without worrying about dangling wires. On the other hand, my old sound equipped wireless Intermountain FT’s are giving me the connectivity fits and polishing the contacts is getting old....I’m thinking of hardwiring them....?Otto K.
I have 3 non-sound GP39-2s.I plan to add the old wipers "just because" to add reliability for the day when a wire breaks.But then again, since I don't have my layout (yet), I won't be running them enough to break a wire anyway.
If you plan to work on the trucks, especially if it involves removing the sideframes be aware the wires may break. The wire are very flexible, but they also break easily. I just think they add complexity and don't do a thing to solve the chief culprit of sound cut outs, dirty wheels/track. To take off the trucks now requires disassembling the entire locomotive versus loosening the screws and having the trucks drop out.
Attached is a photo of the wire from trucks to frame. Looks like the wire going into frame is crimped/soldered to some type of pin. Looks like the truck pickup is still the same as with contact strips. Wires are not called out on parts diagram. This could be a nice fix for the LL/WKW SW's. It would be nice if we could buy them from Atlas, or if someone knows the "pin" used into the frame. Joe D
I’ve not had any problems with the Atlas wire pickups yet.
I have exactly one loco that is making problems, an SD35 with the new wires.The trucks are uneven. It's hard to explain, but when you put the loco on an even surface, you can rock it from side to side. One side of the truck is in the air, while the rest is touching ground. (All other locos with wires are fine.) The thing is: with contact strips you some kind of suspension that would overcome this problem. I guess I should open the where the truck is inside the frame to see if there is anything odd inside that gives this effect. Javier
