I unboxed the train and got it on the tracks. I have 5 lighted passenger cars. I would say they drag a little more than Lionel cars do. I found one frozen wheel, which I fixed. The 21 will pull the dummy unit and one car, after that it needs a push to get started. With 5 cars, it has no chance. The wheels are spinning. This is on an O72 loop with only a small straight section.
The engine does have a weight on it. I pushed down gently on the engine and it actually started to move, so that tells me I don't have enough weight.
There is no room to add a second motor in the powered unit. So, the option is to add a second power unit. I will need to solve the e-unit synchronization problem though.
Does anyone know if you can wire two motors easily to the same e-unit? I could tether the two motorized units and do that. If so, would it be better to bypass the Marx e-units and get a better one?
Thanks,
George
