Amps Drawn by Post War Locomotives

I know a Pullmor motor, regardless of era, will draw 2 amps at 14-15 volts when starting out, and that once to speed, they draw about 1.5-1.7 amps when moving at scale passenger cars speeds.  Its possible that postwar locos, with older e-units and such and perhaps a bit tired, might draw even more.  

Jim,

I don't have a chart, but in my testing of just locos (no train) most of the single motor engines draw < 3 amps  (like 2.4. to 2.7 usually)

Jim-

Most guides I've seen express power draw in watts, but you can determine amperage by dividing by the voltage you run your trains at.

Single motor locomotive - 30 watts

Double motor locomotive - 60 watts

Smoke Unit - 10 watts

Whistle Unit - 5 watts

Accessories - up to 25 watts

18v Bulbs - 5 watts per bulb

12v Bulb - 3 watts per bulb

In most cases a 6-10 amp fast-break breaker or resettable fuse will work well for most applications.

I'm a bit worried that you mention your transformer circuit breakers are worn. Since the breaker (especially on postwar transformers) is designed to protect the transformer (in addition to your trains), I would recommend having these units serviced ASAP.

I don't have an answer to your question, but I am curious about your plans for the protection modules.  Can you tell us more about what you are doing?
