The German Federal Railways Central Office at Munich (work division 2616) has granted technical authorisation for our proposal of supply, in accordance with drawing Elh 00.09.05 and has released it for installation.
Two heating elements of 1.100 mms length, each with 250 respect. 450 W, without protective earth, with straight, separable junction head, are mounted on two divided base plates, which are laid on the ballast bed in the space between sleepers under rods and locking pieces. Owing to the weight of the plates additional fastening to the wooden or concrete sleepers is not necessary.
The base plates are provided with 200 mms long slots. The heating elements are fastened with clamps and screws to the base plate. Screws are fitted with their heads upwards. The two stop and locking nuts have the effect that even with already installed base plates the carrier can still be shifted. The base plates are connected with two mounting links.
Melt and rain water can flow away immediately into the ballast bed. In this way sufficient drainage is achieved which is of considerable benefit owing to the narrowness of the space between sleepers.
