WTIU track hookup question

Legacy or TMCC and MTH DCS play nicely with each other, so there's no need to disconnect one system when you want to run the other. They can both be connected to each loop and powered on at the same time and do not typically interfere with each other.

Thanks Richie.

But do you know whether I can split the WTIU Fixed 1 Output to two different loops that are sometimes alternately connected together or separated?

Thanks,

John

Advice:

You can split a power source and power more than one TIU input from one power source. NEVER connect a TIU output in parallel with another output.

So, in your question- the WTIU has 4 channels. You can connect any number of inputs to a single power source. Each channel output should go to it's track but tracks should be isolated center rail joint between each other.

Again, ,say you have a pair of switches that makes a crossover between loops. A that joint between switches 1 joint center rail is insulated pin or equiv.

I repeat- when doing sharing- you can share channels at the INPUT of the WTIU- but outputs must be to individual track sections or loops and not shared between any 2 outputs.

Further, common (black posts) are able to be true common (connected together) either by wiring or your track plan and all outer rail of all tracks common.

Red post and center rail is where your isolation joints will be.

A little confused.  Here is a diagram showing only the hot center rail connections I am suggesting.  Is this a problem?

Thanks Barry,

Board's interface is a 4-pin connector:  Hot 1- Hot -2 Hot 3- Common.

Hot 1 (loop 1), Hot 2 (loop2),  Hot 3 (Auxiliary power), Common (everywhere)

Translated into your diagram- using 2 channels for maximum signal strength per loop.

You in theory can just use one channel, and your diagram is correct- but depending on size of the overall layout, 2 track loops with losses and reflections, 2 trains and cars possibly loading the signal down (recent conversations on adding inductors to Lionel engines) you may be better served to use 2 channels, for 2 track loops.

Again, as drawn, your diagram technically works, it's just a matter of how much track how much signal is degraded, how much load 2 complete trains on 2 loops.

It's a 4 x 8 layout.  But you may be right.  I could split the brick to the two fixed inputs on the WTIU input side and then use the two Fixed outs (one to each loop) When the toggles are closed making it one big connected double loop -  will there be any problems?

Thanks Barry (as always)
