What is this?

Paul,

 Looks like the same guts as the Proto 2K PA Limited Ed.

That's a DC model, probably with an 8 pin socket under that big black lump at the front.

Here's a link to the TCS Site with some pix:

 Thank you, all.

Given the number of wires I see going up front, it does have a Mars light. My advice is to disconnect the wires from the stock board and connect them to the approriate decoder wires directly. And replace the silly 2 filament Mars light bulb with a 1.5V bulb and appropriate resistor - pretty much any decoder's mars light effect will blow away the P2K one. Repalce the normal headlight with a golden white LED and a 1K resistor.

Forget if I took any pictures of the one I did, but to return it to stock would mean simply cutting the wires and reconnecting them to the circuit board.

 That's the DC constant lighting board and mars light controller, if the loco has a mars light.  There's a NMRA dummy DCC plug on the back of the board that can be removed to plug in a decoder.

 Thanks Sheldon.  Yes - blue box.

That is a DC lighting board. I have not had my E units apart in a long time to remember what they look like, but that little plug is a decoder bypass jumper and there is no decoder.

So it is definately a DC unit.

What did the box say? was the box blue? I'm sure its DC.

 This is the frame from a P2K E-unit I purchased via Hoyardsale.  It was new and unopened.  This is a different board than all the older E-units I have from P2K.  Is this DC or DCC.  Nothing on the box gives me a clue.

Was going to do a test run and didn't want to fry it via my DC.

Thanks for your insight.">
