Something I noticed while driving past the rail yard and while watching "Extreme Machines" or was it "Trains Unlimited" is a trick that both high-speed trains and freight trains use to reduce rolling resistance. The trick is to cut down the rolling (...) (26 years ago, 17-Mar-99, to lugnet.trains)

<snip every thing> After opening my first lego motor, I took a look at that rounded part. Just with my technical knowledge (didn't perform anytest on it) I defenetivly say it is a thermistor and it doesn't have to be heated by the motor, just the (...) (26 years ago, 16-Mar-99, to lugnet.trains)

John is more modest than he needs to be. The lift bridge is operational, just not for extended periods. :) It is a very graceful lift with LEGO motors basically crawling up the towers.

Ok, I wasn't sure if anyone would like that price, I tried to keep it fair, I split the cost by 4 cars. I don't think that's unfair. You'd get all the stuff that went along with the car, if I took and split the price by piece and counted out the (...) (26 years ago, 16-Mar-99, to lugnet.trains)

Hmm... 11+11+27.50+3 = 52.50 (shipping included) S@H wants 66. That gives you the entire last car, including 6 train windows, 3 minifigs and a bunch of black slopes and misc parts from that car and the engine for 13.50. That's not making a LOT of (...) (26 years ago, 16-Mar-99, to lugnet.trains)
