Loss of shunt timer
WebLOSS OF SHUNT Railway safety systems are in many cases based on track circuits. When a track circuit is occupied by a train, the electrically conductive axles of the train short circuit the running rails. The corresponding way-side signal then switches from green to … Web19 de abr. de 2014 · That is why one never starts a shunt motor without the field winding excited. Normally the armature fuses just blow as the current drawn can be very high depending upon the applied armature voltage.

http://genesisusa.com/remanufacturing Railway wheels are made from steel and provide a good short circuit from rail to rail (shunt resistance). Longer trains with more wheels have better conductivity. Short trains, light railmotors or single engines can be a problem. In New Zealand there were problems with light Rm class railmotors not always being detected; see Railway signalling in New Zealand. Trains with a single Budd railmoto…
