@illinoiscentral posted:Hmmm, we should have a "resistor cars", big ol power resistor on a rail car, drawing maybe 5A at 18V, then maybe some cheapo made-in-China digital AC voltmeter reading what the voltage is.
I could add a resistor to my car, but I think I'd have to beef up the pickup wiring for a 5A load! Also, the collectors probably would be under stress at five amps.
I'd probably go for more like 2 amps, plenty to trigger variances due to poor track joints, and a lot easier to manage the current demands.
