    I did some figuring and came up with the following;

    An HO train which travels 6 feet in 15 seconds in going about 24 MPH in scale, right?


    Ps, Is there a tutorial out there, with pics that shows how to take apart and maintain an Atlas HO loco…. I’ve got one, my oldest, that seems to get dirty wheels ALL the time… I was thinking of breaking it down for a closer look. Maybe it has dirty brushes, needs new wheels, or something….

    Thanks… EK

    Wrong! It's 23.727272727272727272727272727273 mph. But I'll let it slide this time ;)

    Can't help you with loco maintainence. Mine are still in a box in storage :(

    Hey Kyle,:thumb:
    My favorite HO speedometer is the distance in inches traveled in 5 seconds.

    In other words, note or mark the cowcatcher position, time exactly 5 seconds, mark it again. Distance between marks = HO scale MPH.

    Like your example, 6 ft in 15 sec = 2 ft (24 inches) in 5 sec = 24 scale mph.
    Quick and dirty.:D :D
