Lionel track issues

You bought it from the wrong guy

Atlas track is great track, but I doubt the track type you are using is the issue with your set. Is that the only set that you have issues with?  As I once mentioned to you I had some issues with flickering lights and also the powered car not working smoothly on some of my subway sets that were stored for long periods of time. In my opinion it is not just the track and rollers that you have to watch, but also the pin that holds the roller can get dirt or oxidation. I have used electrical contact cleaner that is plastic compatible with electrical items at times with good results. This is where the contact cleaner can come in handy when trying to clean hard to reach places for electrical clean up. Also sometimes just a good run of the set for a few laps at higher speed was enough to solve contact issues in my case anyways. Have any of the cars been opened up before? You have to watch not to pinch any wires when putting the cars back togther or else you may get electrical problems. If nothing seems to fix it, you may have to have someone check it out to see whats going on. Good luck.

da flikrn lights is cool,back in da 80s the subways always had that.just da rest is not good.

I use Goo Gone. I pick it up by the case, from some guy near the FDR.

Thanks!! Thanks Johnny, ive opened up the cars maybe a few times. It only happens with the R142

This happened at least twice but sometimes sparks would come from the wheels and the train would shutoff. Also,i charged the battery already and sometimes when i turn on the Train and press direction, the Train just restarts

You may need to let it charge ., for say .. 5 hours.. That should take care of it
