Sorry about that i posted the question from my phone guess i didnt notice the 9'. I added a couple pieces of 9" track to the original santa fe circle track. I guess what i need to know is. Does the ez track have certain pieces that go together or is it all universal? Meaning as along as its bachmann ez track it should work fine with other ez track. Correct or not? Any feedback is helpful

I have a santa fe flyer train set and recently added 9' straight track to the curved track that came with the set. When i connected all the pieces i noticed the train wouldnt go in reverse. HELP!!!
is this issue because of the track or my controller? The controller started to smell like burning plastic and it got hot. This never happend with the original track alone. Im a rookie so any suggestions would be helpful
