The Leap from the Water Tower(1915)

Rand, a vengeful discharged fireman, tampers with the airbrakes of a large freight locomotive making them useless on the long descent from the summit of Pine Hill to Lone Point the following day. Learning of the impending peril, Helen dashes to a water tower under which the train must pass, climbs out on the spout, leaps onto the roof of one of the cars, and warns the engineer in time. Helen's heroism wins her another offer of marriage, this time from Wadsworth, the freight engineer, but once again she opts for next weeks hazards instead.
