that will works but you will need 2 joint like that because when to train motor
will cross over the joints both front and rear wheels are connected and will
short-ciruit the 2 modules

joint with sticker (scoth tape)
use 2 lego switch like part 6551 to feed the insulated track section between
the 2 modules (one feed by side A the other by side B), turn them off at all
time except when you what to cross a train over then turn them on alternatively
one at a time to make the train cross the insulated section. But make sure not
to turn them on both at the same time. Also make sure when one switch is one
that the train will not go ever the other section. You can also go check
Matthew Bate Train Depot site for more info.
