I was working on a hump yard decoupler and was playing around with adding mags to the track using the 2x2 tile that has clips to hold the mag. What's really cool is how you can make a train car hop over the mag on the track. All this play was big (...) (25 years ago, 6-Jan-00, to lugnet.trains)

Does anyone know where I could get a 3225 for a decent price? Anyone have them on clearance locally? I would VERY much appreciate if anyone could help me out. If you wanted to trade for it, let me know too. Thanks. Tim Strutt 8^) (25 years ago, 6-Jan-00, to 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)

LEGO train knuckles don't lend themselves to decoupling. Has anyone got a good design (either as part of a switch engine or fixed to the track) design for an automated separator? I'm close to an in-engine (but very ugly) solution which can pry a (...) (25 years ago, 6-Jan-00, to lugnet.trains)

(...) I was just experimenting with this a few days ago. An RCX using PWM does a far better job of driving the LEGO train motors than the simple variable voltage from the LEGO train control. You can make a train creep around just above stall speed (...) (25 years ago, 6-Jan-00, to lugnet.robotics.rcx, lugnet.trains)
