I recently purchased a proto 1000 A and B Engine setup, both are powered. I am working on a new double loop layout with some sidings. I have a bachmann power supply that came with a set running my layout which is dc only for the moment. Previous to the proto 1000 engines I ran a bachmann 0-6-0 and a model power F2 diesel, both engines run perfect in all speed ranges. My proto series will not power up and start moving untill i have the speed set on 40 or higher and if I run the A engine only it seems to run smoother than with both. This is my first experience with two powered engines and with anything other than cheaper engines. When I try to run both proto engines and another engine it doesnt run well at all. I am new to muliple engines on one track system so any help or insight is greaty appreciated.
