I'm new to AF and more accustomed to solid state engines which run relatively cooler. I only run AF around the Christmas Tree on a small loop of traditional track. One thing I'm a little nervous about is burning out armatures. I guess re-wrapping them wouldn't be impossible according to Thomas B. Barker's guide, but I'd like to avoid going there! I favor the vintage diecast (heavier) livery and cast steamers running at slow speed since the loop is small. After letting them run an hour or so they are fairly hot, particularly the reverse unit lever. I'm thinking the armatures will run hotter at slow speed due to the strain? Is the heat factor typical for AF? I do a complete break down and servicing to the engines before running them each Christmas which includes cleaning the commutators and lubing. Are there any indications the armatures are overheated such as visible smoke or smell?
Also, the #740 hand car runs real hot despite the bushings being in very good condition and the brushes being centered (I actually purchased it as NOS). I don't let it run more than 20 minutes or so due to the high heat. Is this normal for the hand car? These trains must have been somewhat sturdy as they were run by youngsters back in the day!
Thanks...Rich
