Abstract
A connection for joining the edges of a roof sheet to the wall of a railway car without the use of fasteners such as rivets or welds. The connection is weather-tight and includes an interlock feature which effectively carries the loading encountered during operation of the vehicle. A modified version of the interlock forms a trough for channeling water towards the ends of the railway car.
