Proto 2000 Engines Manufacture
Jim poses this question for readers:
“Another of those questions that was sparked previous to a purchase. I saw a number of HO Scale Proto 2000 engines (different types in original boxes) and when looking at the guts of a few of the engines, I saw wires to a PCB. The question becomes; are all Proto 2000 engines DCC? If not, why is there a PCB on the top of the weight in any of the engines?”
Please comment below if you can assist Jim.

All P2K engines do not have DCC plug. Many have DCC plugs but most do not. Some P1K’s have the plug. The only way I know of DCC ready loco is the box will have “Limited Edition” on the flap (top of box) Cheers, J B🚂
Some proto 2000 locomotives have an eight pin plug so you can plug in a decoder. But not all of them have it. If it dates dcc ready on the box then you can install an eight pin decoder.
The PC board is for the lights. It provides proper voltage to the incandescent headlight which is much lower than the track voltage. It has a circuit for a gyra light which is simulated by alternately powering two filaments in the upper bulb. On the later units you may find an 8 pin DCC connector as well on that circuit board. On B units these circuit boards are sparsely populated because they have no lights, only the track connections which provides the power and the motor connections.
