Thanks for all the inputs.  As for customers messing with my trains....not really a problem.  They are about 10 feet high and along outside walls.  It would be really hard for them to get to the trains.  Yes, I do have some really big, ugly bouncers, who frown on folks messing with my trains!  After hearing your feedback, it probably would be simpler to just run the extra track.  Thanks much!!!

I have a bit of a unique situation.  I have a large Nightclub that I have 2 HO scale western diaramas in.  I'd like to connect the 2 diaramas & run one train on both.  They are about 100' apart, & I don't want to have to run 2 tracks.  Is there any type "Y" connector that would allow me to run a single track between the 2 diaramas?  Also, I'm not set up for DCC & a manual switch would be out of the question.  My grandfather had a similar set-up and he used a "Y" on his.  He actually used a switch with a weak spring that would allow the locomotive to force a switch as it went thru.  I've tried this method, but keep derailing.  Any suggestions?
