Michael and Clem,
I scoured my basement, but do not have a box(with product no)for the Rail King, Dash 8 with factory installed PS2, which is having the problem. Have tested other PS2 engines, and they don't have the problem. I believe the 3 switches are Ross switches. ( the Dash 8 also shows the hesitation on most switches on the mainline. but have not tested them yet) And this is a Dash 8, not an E-8, fyi. ( Have not tested my E-8 yet). I did clean the drivers and pick up wheels, but to no effect so far. Just wondering why this is just now surfacing as it has run very reliability for as long as I have had it.
Will let you know what my engineer friend and I discover tonight. Thanks for your persistence.
Ron
And the PS3 SD90 showed no problem.
