(...) I forget if I already replied with how nifty this is. I spotlighted it, I put in a news article at ILTCO (we're having some domain problems right now, a temporary url is iltco.northcomp.com) and I added it to the .trains header That ought to (...)

Awesome cars! The shovel roof really looks nice, and the cars themselves are incredible. The ends have gotta be my favorite part, with the drop down deck and the entire thing being SNOT. Very spiffy. -Stefan- (21 years ago, 30-May-03, to lugnet.trains)

(...) Joining in here, I don't get why it's so hard for Lego to make a new monorail. Can't they just put together a new spur gear system (And give the cars real couplers while they're at it)? Doesn't seem like it'd be that hard. -Stefan- (21 years ago, 30-May-03, to lugnet.trains, FTX)

(...) Sorry, my earlier post should have been more clear. I was just commenting on the fact that in general a resistor is _not_ a good way to reduce voltage to a train motor. And you recalled correctly: diode's are "one-way". Thats why you need to (...) (21 years ago, 29-May-03, to lugnet.robotics.rcx, lugnet.trains)

Hi all, after an active phase of virtual building under ML-CAD there has now a new train been built from real bricks and uploaded at Brickshelf. That train consists out of the recently posted BR24 engine and 4 brandnew passenger cars. All this (...) (21 years ago, 29-May-03, to lugnet.trains)

(...) <snip> (...) All bets are off WRT to the "momorail" ;-), but as far as monorail goes, Brad Justus was asked point-blankedly what the chances were that TLC would rerelease the monorail, and his answer was 0%. All parts specs for the motor are (...) (21 years ago, 29-May-03, to lugnet.trains, FTX)

(...) The problem with inductive load is that when current is interrupted, they generate large voltage spikes with reverse polarity. The diode absorbs these spikes and avoids destroying the driver... Philo (21 years ago, 29-May-03, to lugnet.robotics.rcx, lugnet.trains)

(...) I'm no electronics engineer by any stretch-- A diode, iirc, allows DC current to 'flow thru' in only one direction. What would a diode do across the output on the top of the train motor? And why would one be good for 'inductive' loads such as (...) (21 years ago, 29-May-03, to lugnet.robotics.rcx, lugnet.trains)

(...) VERY unlikely that it'll happen... LEGO didn't produce everything themselves and all tools are gone or so we were told. This has been discussed a few times before. But IF monorail were to return, I'd much rather see new things... the 6399 was (...) (21 years ago, 29-May-03, to lugnet.trains)
