Running 2 trains at once

Threaded View
Hi

We're about to add a second 9V train to the family and that raises the
question of power.  I know you can run them both on the same track at the
same time if you're ahppy with them going together.  We're thinking of
having two separate tracks with a connecting siding between them in which
we'll cut an isolating break.  But the question is, if we make a mistake and
hook things up so that both power supplies get connected to the same piece
of track, what damage protection is there in the power supply or motor to
prevent anything nasty happening?

Re: Running 2 trains at once

well...in that case I would say to use a transformer that has overload
shutdown feature built into it.

MRC Tech series controllers come to mind but there may be other names
that I don't know of too.

or for the best I would say to gap the connecting siding into its own
'third' block and hotwire up a doublepole switch to it to both track
circuits.

the way that could work is say we have two oval and one long crossover
track that connects both...throw the switch to #1 and a train from
outside circle enters the crossover block...stop it there...flip the
switch to #2 and the train is immedately on insidle circle power instead
as it exists the block onto inside circle itself.
--hope that made sense?

The lego transformers have overload protection built in.
If you just have two loops with points between them, you cant actually
get them set up so they can short out.
