Piece of cake, diesels are less "fiddly" than steam for ERR installs. My biggest job installing something like this is I usually like enhanced lighting, things like adding marker lights, ditch lights, etc.
That you will need to add a MARS simulator. I use the ngineering.com MARS Simulator for. You have to add a filtered DC power supply, but it'll look better than the Williams MARS light ever looked!
John, Which LEDs do you use for marker lights, ditch lights, mars lights? What do you use for the filtered DC power supply? TIA Pat B.
