It would nice if we could just reverse some of the circuit instead of having to use a rectifier (something about that word makes me laugh). Nice tag line Rob. jt (...) (22 years ago, 27-Jul-02, to lugnet.trains)

We have been experimenting with an external bridge rectifier for our Rail Racer events. The only drawback is that the one we picked out (lack of electronics experience) draws 1.5 volts away from the output going to the track. Not a big fairness (...) (22 years ago, 27-Jul-02, to lugnet.trains)

I haven't looked at the schematic, but would it be possible to add some type of rectifier in there? (I'm not an electrical engineer, but I remember something about a rectifier allowing current to pass "one way"... And I think I know exactly what (...) (22 years ago, 26-Jul-02, to lugnet.trains)

I have been intesrted in this topic as well. Thanks for doing the schematic work. I was thinking about about mounting a linear variable resistor aka Thumbwheel Trim Pot (see: (URL) on the PCB board opposite the power connector. (see: (URL) 1st (...) (22 years ago, 26-Jul-02, to lugnet.trains)

I was thinking of a GWR themed signal box, not needed now. Think I'll go for a coaling stage to go with the water tower. Mark "Jason J Railton" <j.j.railton@ntlworld.com> wrote in message news:GzuvG8.2Hv@lugnet.com... (...) enough (...) layout at (...) (22 years ago, 26-Jul-02, to lugnet.trains)

Sonnich, Nice site, good info. I want to figure out how to keep the controller from going in reverse, I just want it to only go forward no matter which way the knob is turned. Any clue on how do this? jt (...) (22 years ago, 26-Jul-02, to lugnet.trains)

Once upon a time (...) there was a discussion about the 4548 Train Controller about how to limit output in order to limit speed of trains. That inspired me to create a page describing the problems with the Train Controller. I have created a (...) (22 years ago, 26-Jul-02, to lugnet.trains)
