A training Video for Paddling and changing power fuses on Class 456, 455, 319 and Slam Door units. A Network SouthEast Training Video for Drivers in the South Central Division.
People back then had more respect for danger than they do today, due to health & safety. There comes a point when too much h&s leads to complacency. Back in the BR days, they may have done things differently, but all staff respected the dangers.
Exactly, and all of the practices in this film are safe. When the narrator said that it was most important to absolutely ensure that the electrical loads in the train were isolated by means of the main isolator, that ALL shoes are firmly off the juice and firmly held by the paddles, means that there is no risk of explosion during fuse replacement. People had more common sense back then.
On the class 71 when the pantograph was in contact with a live overhead wire were the shoes live? How did things work on the old 1200V side contact system on the Manchester to Bury line? I remember that these units carried a short circuiting bar which was a different design with a heavy metal ball on the end of the handle. Was there a type of shoe paddle for use with Regis system? Could any work be done on these units without the traction current being turned off?
@@ElliottHurst: At least the Electrostars still do have the shoe fuses - they're quite visible (either covered with the electrical warning [Southeastern] or with the warning above the fuse [Southern]). Can't remember whether the Desiros and Aventras had them or not, but I'd think they do?
Ok, so yo paddle up all of the shoes and check that there is no power to the unit. But what happens if something knocks out the paddles from under one shoe? Say an animal gunning alongside the track, or some object or damaged shoe gear sticking out from a train passing on the other line. Wouldn’t it have been safer if means had been provided for the normally live parts to be bonded to the running rails to prevent them becoming live unintentionally?
*g2macs* If you mean the large copper ribbon fuses above the collector shoe on the bogie the design is deliberate. These fuses wouldn't usually blow as the sub-station circuit-breaker would normally go first. The current they routinely handled was over 1,000 amps at about 750 volts.
