it’s going to drive the collectibles series that Lionel created into a price depression. The parts might become worth more then selling the engine.

I upgraded a few of the early gp’s. Are you saying these didn’t take the standard rs

upgrade being offered at the time? Opps - Just got it - the pub motherboard had no allocation for both rs board and rs power supply? Weird.

What parts are needed to add command and railsounds to this engine.  Are the parts available?

Remember that the electronics configuration in this loco (and its twin, the 6-52197) is unique.

The TMCC upgrade portion is straightforward -- remove the modular 104E reverse unit and install an R2LC.

But the sounds weren't designed to be upgradeable, with the one-piece SignalSounds board in there now. Adding RailSounds can certainly be done (RailSounds 2.5 system or a new motherboard and modular RS3/RS4 boards) but it's more involved than simply adding the two boards from the upgrade kit.

RailSounds 2 boards do work with TMCC, but two of the six versions have PICs that won't recognize the commands. You really don't want to use these -- they're really big, and all the connections are hard-wired, which makes them a pain to work with.

RailSounds 2.5 boards are also TMCC compatible, and I can only think of one PIC (from a RailSounds Christmas sound car) that doesn't recognize TMCC commands. These have all the usual Leoco/JST-EH connectors, are smaller in size, and much easier to work with. Most of the TMCC-equipped Geeps in the mid-1990s came with these boards before graduating to the modular RailSounds 3/4 system in 1998.
