Hello, I just got my first second hand engine from the train store. Its a fleischman 7230, which I liked the model of and will be used to pull steel cars. It doesn't have a flywheel, but it does have traction on all 4 axels. I also got some second hand sectional track, which I made into a weird looking loop, I solderd the track together and also the power feed. Then I cleaned the track (what is the best way to clean it?) and the wheels on the engine. I also put a current meter, to see how much current it takes. Anyway, the train runs at its slowest on 150mA (5 volt, just after the lights on the engine are fully lit) it then runs its own length in about 1 to 1.5 seconds. at this speed the engine sometimes stalls (while still using the same current) and I feel the motor when I touch the engine. After this the speed increases when the voltage increases and it runs very smooth. on 12V and holding the wheels it takes about 320mA, as I would love to run it on DCC. So I read from lot of sources that your train should run smooth if you are going to add a decorder, ofcource this is my first train I don't know what smooth means. So could anyone share, how good this one is running, or how I could get it better? And if the lowspeed control will be better when using DCC?
