how do i run digital model trains on a double track withtwo points as a crossover?

Answer 1

Are you talking two DCC (Digital Command Control) Trains running on two parallel main tracks in a rough oval shape with a cross-over or two ??

DCC permits you to run the two trains at the same time without different power-blocks. Also DCC is AC power based, so you won't have problems with polarity as you cross over.

Just pay attention so they don't run into each other !!

There ARE sensors and systems that will stop and start the trains without operator action, though I haven't tried them yet.

Get a copy of "Model Railroading" magazine, or a DCC book from your hobby shop for further information.

Good Luck

Answer 2

Using live frog points you have to use insulating joiners to seperate the frogs from each other and from the main lines.
Four ins-joiners in total. For Drawing of above send me your email add to [e-mail]
