Thank you Larry.
I took your advise and had it checked out. Funny after nearly 80 years the cord was pretty good, and the transformer tested well. I hooked it to the track, but do not like this type of transformer as the voltage selections either run the train too slow, or too fast. I would prefer a more variable speed transformer. My engine was built between 1933 and 1939, and that too is in excellent shape. Adding several cars seems to need about 14 volts or so. Less than that runs too slow, more than that runs too fast. My transformer doesn't have the perfect setting. To get 14 volts, I need BF terminals, which is constant voltage. Using BU, I can't find one speed setting that works best as any setting is either too slow or too fast. I'd like to slow down around curves, but this transformer doesn't allow that. Would you have any thoughts regarding recommending a transformer for me. Should I buy a used transformer? I'd like more track, so could attach to the track in multiple locations for consistent voltage, but would like more variable speed control.
