A device placed in the rail track to arrest a forward runaway tram. The front axle of a descending tram traveling at normal speed depresses the catch and allows it to drop back in time for the back axle to pass over. Should the tram be traveling at excessive speed, the tail end of the catch arrests the rear axle. Mason
