Bachmann Gandy Dancer hand car ?

what is the steepest grade this little guy can climb? I am building a runaway coal car layout and was hoping to use the hand car as the coal car.

If there’s any way to put DCC in one of those little things, lemme know. I’d love to have one I could use to try to outrun a train. lol
