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?
