circuitron snapper question

Model Railroader General Discussion (Model Railroader)

I want to activate a relay when I fire my Circuitron snapper capacitive discharge unit. (i.e. Wire the relay in parallel with the one of the switchmachine coils.) Radio Shack has 1A, 2A, 5A, and 10A relays. Will any of these work? If so, which one is best?
