Thanks Daniel. I didn't realize that about a TIU. I was originally going to put my toe in the water and just use DCS Remote Commander for basic DCS on my first MTH/DCS engine. But, if a TIU replaces the powermasters, then I'm happy to use it and scuttle the power masters (or save them for Christmas layouts).
Daniel and GGG, here's a quote from ADCX Rob on one of my threads in 2015 regarding the power masters having fast-acting circuit breakers when I asked if they eliminated the need for circuit breakers.
"Yes. They have fast acting 7 or 10 amp breakers built in."
He's a much smarter guy than me on these things.
