For several decades there has been a debate on weather it's alright to run older analog direct current or 'DC' locomotives on digital command control 'dcc" without a decoder.
While most digital controllers do have a feature to run older analog locomotives it has always been believed to be a risk to the motor due to there always being voltage present in the track.
The kind of energy is also much different with alternating current instead of direct current so today I decided to put it to the test and run three different eras of locomotives.
I let each one idle for an entire hour to see if the motors would overheat, checking in on the temperature every 30 minutes or so. The results were not at all what I expected.
