Got a simple Question!!!!

[Larry]

I was redoing 5 Ath. engines & was installing the LED lights front & back. After I got everything together & wired up I sat the engines on the track for a test. 2 of them ran in the wrong direction. I have a diagram on my workbench for which way the clips are turned to make sure the trucks are in correct. Well, in the photo you can tell that doesn't make it correct. All 5 frames are exactly alike & all trucks are the same. But, on 2 of the engines the trucks have the clips turned the opposite way.
This is another 1st for me.

Is there a difference in front and rear trucks?

yep, there sure is. If you put them in wrong they will hit another engine head-on. Been there, done that.
