Checked out Legacy remote with 180 watt powerhouses wired to TPC 400. Ran a Legacy engine with no issues with that and used the bypass switch we created and ran with the Z4K transformer.
A club member brought down his 259 prewar steamer and road-tested it with Legacy remote and TPC. Ran perfect with TPC which we have set in conventional mode so we have the ability to operate ANY 3 rail trains from 1900 and on to present day trains with a cab-1 or cab-2 remotes.
I guess bending my knees in a funny position has paid dividends to the club.
