Lyddrail Posted May 12, 2014 Share Posted May 12, 2014 I don't remember seeing many good pics of the raised cable routes, however we still have some evidence in situe in Kent. These were for carrying the HV feeder and pilot cables since moved into surface troughing. Taken at North Halling LC. Below a bit of the support wood, the cables were encased in wood sections like the DC 750v trackside cables in early times. Cheers. Link to post Share on other sites More sharing options...

Nearholmer Posted August 11, 2015 Share Posted August 11, 2015 Gents The 1930s SR electrification schemes used wooden cable enclosures in two modes: - wooden boxes, about 10" square cross section, made up of planks top, bottom and sides, heavily creosoted and held together with brass screws, mounted by galvanised steel brackets onto concrete posts. These carried the high voltage (33kV) and pilot (control and protection) cabling; and, - wooden trunkings, about 5" square cross section, made up of two bulks of heavily creosoted timber, each with a semi-circular hollow milled out. The two baulks fitted together, more brass screws, to form a protection for DC cables laid on the surface of the ballast. Both types were a great nuisance from a fire point of view: on a dry day, one fag butt thrown from a train window, and a crumpled copy of Evening Star were enough to start a good old conflagration. They were largely eliminated during the 1970s/80s, as cables were replaced with modern types. Kevin Link to post Share on other sites More sharing options...
