Power = Voltage x Current.

If the engine is "doing nothing" with 16V DCC track voltage pulling 1.75 Amps that's a whopping 28 Watts. That 28 Watts is going into the engine. If the engine is not moving then that 28 Watts is essentially being converted to heat inside the engine and something inside is getting REALLY hot and probably melting! Like GRJ says, a DCS engine just sitting there should draw just a few Watts. Even if it has started up with audio at full tilt the audio power only adds a couple Watts max.

I'd take another look at the hobby shop's metering. DCC track voltage is a digital-like signal that doesn't play well with some meters.
