Hi everybody, (...) Correct. 7860 is the set number. A quick Google search turned up mostly auctions and sales pages, no useful description of this set, so here go some basics for the interested ... Both the red and green light are controlled (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) Could you use a "bi-color" LED this way? Polarity one way, light is red. Polarity the other way, light is green. Polarity alternating, yellow! (Ok, that last part is probably a pipe-dream... <grin>) Can DCC output a voltage with either (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) I was thinking of something similar. Using 2 outputs you could control a 3 lead Bicolor LED. Or with a small NAND gate as well, you could use the 2 lead style LED that you mention. If you don't mind the LED always being on it only takes one (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) Yes, otherwise you could only run a DCC loco in one direction. ROSCO (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) Hi Horst, that's a great picture. Yeah, that's what I've been striving for, a layout of roughly that complexity and automation, but without nearly as many wires. The remote controllers (along the bottom of the picture) being replaced by the (...) (20 years ago, 22-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

(...) You can get 3 colour LEDs that are designed to work that way. Not sure, but think they are orange as 3rd colour though. (...) Yes it can, motor outputs are reversing. So, using any stationary decoder that can power reversing switch machines (...) (20 years ago, 22-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) I think with a red/green bi-colour LED you can get any colour between the two by varying the mark/space ratio of the alternating waveform. A DCC controller varies the mark/space ratio of a square wave in order to drive the motor at different (...) (20 years ago, 28-Oct-04, to lugnet.trains, lugnet.parts.mod)
