The cameras used are essentially video cameras. They should have no problem freezing motion. The bigger challenge, to me, would be firing the strobe at a high enough rate. Face/Off at PKI has cameras at the bottom of the second hill, where I assume the train is going about 50 mph.
It's interesting that all of CP's on-ride photos use one camera at a time (two for the B&M's, one each side). A lot of parks use arrays of cameras.
