i was wondering how good these little engines are if done right ? i notice that mine take a lot of power to run and the way i mean is this . i have a railpower 1300 and it needs 60 or more on the dial to run but at times it slows down but dont stop then picks up more speed . deos this mean it needs a good cleaning and grease ? its a alco d30 steam locomotive santa fe # 99 . this is for ho scale . 4x6 with 18'' turns . i have a another 0-4-0 atsf steam switcher and it only take about 30 or less on power on the dial to run real good with no drag or bogg at all. great site for help and advise form you guys and gals too .
