| I was running my new PRR E-8 and B&O Pacific today on a temp layout, and noticed that compared to my B&O Pacific the E-8 is much slower (new versions DCC/Sound ready for both).
I am running Stainless Steel track with aristo 10 amp power supply and controller. I have 24v over the entire track and amp draw is constant at about 2 amp at max throttle on both.
Has anyone else noticed this is it normal or do I have a problem.
Thanks, Ron

| Possibly same transmition, but different sized drivers are causing the Pacific to run faster. The large drivers on the Pacific will cover more track with each rotation than the smaller E-8 drivers.

| The Aristo Ultima 10 amp power pack under a one engine load like the E8 will output 21 volts at best. The Pacific will be less of a load on this supply and the output would be higher when running the Pacific.
This is due to the Ultimaa being a non regulated supply and tyhe output drops under larger loads.
The 13 amp Elite is usually at 22.5 volts but can be tweaked to 24 volts. This is a regulated supply and the load does not change the output voltage level.
