I have a few nephews/nieces, 6~10 years old, and just like my grandfather before me - I was surprised by their lack of ability or willingness to control the speed of the choo-choos and keep from sending them at rocket speeds and sometimes off the track. Their lack of 'control' isn't only mischief/malice, but also attributable to a lack of motor skill and lack of experience/familiarity. I think I want to set up an engine or two for them that only go 'so' fast and won't fly off the track, till they can mature and learn a bit. I have a couple of postwar 2065s that they like for the green LED registration lights on the front and red LED tender tail-lights that I've added.
Anyhow, I'm running conventionally and thinking that if I reduce the voltage to the brushes without reducing the motor coil voltage I can keep them from 'racing' so fast. Whaddya think? I searched the forum a lil' bit and didn't find anything for conventional postwar motors except maybe a string of diodes or rheostat but how much additional amperage am I 'adding' to the motor to do that? Is there some small switching regulator/voltage limiting thingy that can deal with the amp draw of the pullmor motor?
ideas/suggestions/laughter/eye rolls are welcomed?
