Dave was on site all weekend as usual, and was attempting to loosen the bolts on the radiators with an air-tool, but discovered it seems to be broken, so he went to remove some of the brake rigging from the spare bogies, but found all the bolts seized. Wes Needle paid a visit with his wife Keren & their two children on Sunday to look in on progress and take the family for a ride on the train. As I was working on 50008 last Sunday & therefore missed the workparty, I went up today & fitted the second small board behind the field divert contactors that houses the ETH detection relay HDR, the ETH earth fault relay HEFR & it's associated resistor Z62. I wired Z62 & HDR, but while wiring HEFR, I seem to have mislaid a wire from one of the ETH interlock relays, so finding it is the first job next time I am there.
