Well you guys have a lot more knowledge than I do.  But it is brand new bachmann NS track as are all the turnouts.   The engine has a tender.  Also it only happens on this one of 15 turnouts on the layout.  It appears that the engine stops with the drive wheels on the frog and short out the hole layout.  Hope this helps.

I have an old 4-6-2 steam engine that still runs great.  However, when it comes to this one switch it stops dead until I move it forward.  It is about 50 years old.  Any ideas.

I just received my Bachmann crossover and it says that it comes unpolarized.  What does that mean and what is the best way to polarize it.  The directions were not very clear.
