Hi everyone...I have the NYC version (#1933180). I haven’t been having the same problems as those on this thread, only because I run it on the factory setting of engine 1. However I have encountered another problem which you might want to look out for. Several times since I started running the set the rear unit has lost signal and either stopped dead or after I put in a direction change kept going in the old direction. In any case this led to one engine trying to pull the other or the two engines pulling against each other, resulting in a horrible sound and trauma to the operator (me)! I assumed it was a bad connection on the track or dirt on the track but after cleaning everything up it was still happening. I just figured out what the problem is. When I took a look underneath the rear unit I found that the two pick up rollers in the rear of truck do not roll at all and were covered in crud. Basically those two rollers were acting as a track cleaner! I was thinking of trying to oil the rollers but since the front unit also has a problem which is an incessant ticking sound that I can’t seem to isolate I think I’m going to return the set. It’s a shame that we are all having these problems because it is a really beautiful engine.
