 | | How do I power a long track? —Mark Assi
|
| | | Hello everybody, I have a train track that runs around the perimeter of my son’s bedroom on a platform that extends out from the wall. The problem is that the train seems to really slow down around the opposite end of the track from where the power (...) (20 years ago, 25-Dec-04, to lugnet.trains)

| | | | | (...) Hi ! This is a problem we encounter all the time. The solution is quite simple - add extra power connectors at selected locations around the track. Use the long Lego wires (hard to get) or make your own - cut a shorter wire and splice in some (...) (20 years ago, 25-Dec-04, to lugnet.trains)

| | | | | (...) I agree with the advice John gave, although not completely with the "why"... the drop in voltage is, in my view, due to the resistance at each track sections abutment with the next.

Carefully apply a little bit of "contact conditioner", available at computer and (...) (20 years ago, 26-Dec-04, to lugnet.trains)

| | | | | (...) The GMLTC has this problem in our 'small' (approximately 100 feet of track) loop, because our larger 8-wide trains are heavy and we really work the motors hard. Our solution? Add another speed regulator! We put one at each end of the dogbone, (...) (20 years ago, 26-Dec-04, to lugnet.trains)

The explanation that was put forward was that the controler that was running at a slightly lower voltage would (...) (20 years ago, 26-Dec-04, to lugnet.trains)

No problems occured, since the LEGO equipment is really sturdy and kid proof. I (...) (20 years ago, 27-Dec-04, to lugnet.trains)

I kind of liked the idea suggested earlier about simply running two power lines from the same regulator to (...) (20 years ago, 27-Dec-04, to lugnet.trains)

My layout has a circuit of 106 pieces of track and I use parallel-connected feed wires, one at each end, so that the through-sidings on each (...) (20 years ago, 27-Dec-04, to lugnet.trains)

Total of 1 motor. I was thinking that maybe I had too many cars on it, but (...) (20 years ago, 27-Dec-04, to lugnet.trains)

Hello, Just something I thought of that may be worth bringing up as trouble shooting your problem would be making sure that your layout around the perimeter of your son's room is level all around.

Turned out we were using an underpowered power supply - we (...) (20 years ago, 31-Dec-04, to lugnet.trains)

| | | | | (...) Hello, It's look like you were using a few motor on that outer loop. With a single Lego regulator which can supply about 1A (1000mA) you can run 2-3 motors. Each motor use about 300~350mA under normal load. If you run heavy train they need (...) (20 years ago, 31-Dec-04, to lugnet.trains)

This is pin and function compatible with the chip in there but (...) (20 years ago, 31-Dec-04, to lugnet.trains)
