Yes, the idea is to make a page about it and how to lower the output voltage
and how to get more power from it.
As A part of it I draw a schematic of it, which I'd like to publish to with
calcualtions.
The schematic is taken directly from the LM317's datasheet's examples.
Still, I cannot figure the resistors out. Seems to be some custom designed
resistor pack. Will check tonight. If anyone knows please come forward.

| (...) Agreed. Ask them! Typically, though, publishing things that you reverse engineer is a lot less likely to cause trouble than releasing information that you obtained from the source. Presumably you've reverse engineered the controller? (22 years ago, 4-Jul-02, to lugnet.trains)
