"My current project is building a 4 X 8 HO layout. I am force to use very tight turns. This requires me to us small Diesel and light steam. I am using all TCS decoders and was wondering if you have any suggestion for my problem. The Diesels run fine because they all have duel flywheels. My light steam is the problem because the motor is in the tender and has no flywheel. The light steam stalls going over crossing and dirty track. Do you know of anything that I could install to get my engine over a dirty spot in the track?"
