(...) For fun, with a second sensor you can make a gouvenor, which takes it speed from the track, and with a third motor you can change the gouvenor setting :-). It works reasonably with the ligth sensor as well. Then it is analog. But I found the (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx, lugnet.trains)

A few (Hah!) years ago we used to get that realistic slow train speed by running our Lionel "O" gauge and American Flyer engines on DC. We used an AC Gilbert rectifier that was a full-wave selenium unit. By adding a switch we made it be only (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx, lugnet.trains)

(...) PWM stands for "pulse width modulation". The LEGO speed control changes voltage as you turn the knob. An RCX turns the motor on and off really fast but always supplies full voltage. So half speed is a 50% duty cycle of full power, rather than (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx, lugnet.trains)
