Thanks John.
As you know I use batteries in all my engines, but I have 2-3 that, even with a 12v battery inside, just don't go as fast as they did under TMCC or DCS. They go plenty fast for my purposes, but I can't figure out why they are slower than before.
My Williams brass N&W 611 for example. Using PS2 it was plenty fast, too fast actually, but using a 11.1v (not 9.6v) battery it barely got up to 48mph. Last night I swapped out the 11.1v (not 9.6v) for a 12v pack and gained 6 more mph to 54mph, still below what the engine did using PS2. I have 2 others that are even slower at top end, but they still use the 9.6v battery. One is a Lionel 4-8-2 and the other is a 3rd Rail E7, I plan on putting a 12v battery in the E7 but might not be able to do it in the 4-8-2 (limited room in the Vanderbilt tender I built).
I'll have to ask on the Freerails forum, maybe the Deltang receiver is using up some of that voltage.
I also have an Atlas F3 and GP9. The GP9 is twice as fast as the F3 and I think they have the same motor/gearing/trucks. I may have one wired in series and the other wired in parallel, need to check. The GP9 clocks in at 100+mph!!!
