Sharp-eyed Mechanical Officer spotted an interesting addition to the livery of 66030 at Hereford on 11th August.
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.
It was quite a busy weekend with Dave, Chris, Tom, Steve & Sarah attending both days and Ian, Pete & Mark on site Sunday. Toby the dog, who could become un-official mascot with regular site attendance, was also there!! Ian & Pete continued with the quest of torqeuing up the big end bearing caps, only a couple left to do.
Tom repaired/replaced as required all the runner timbers below the droplights. This completes all the internal frame repairs in both cabs. The potentiometer stand in Renown was straightened, welded, cleaned and refitted by Chris - it had been damaged and bent during the removal of the ETH/aux gens before RRRG bought the locos. Dave continued cleaning up under the no1 cab floor in Renown, also assisited others.
Steve & Sarah continued identifying cut cables in Renown concentating at the cubicle end. They opened up the Battery Isolation Switch to identify cables, the rear section of the switch was removed to assist this process.
Mark removed floor-mounted conduits from the generator area in Repulse. The conduits will be replaced with those removed from 50040 prior to its scrapping. The cleared floor was cleaned.
Ian & Pete stretched another two pistons' worth of stretch bolts, before having to abandon this until a spanner can be bent, as the power unit internal structural webbing is now getting in the way of using the spanner properly. They then helped Dave loosen the bolts on the spare bogies to allow the traction motors to be removed sometime this year for overhaul. I test fitted the other two small boards that go behind the divert contactors, and found they fit easily. These two boards house the ETH overvolt relay HOVR & it's associated resistor Z24, the ETH voltage sensing resistor Z23, the ETH earth parallel resistor Z69, the ETH earth fault relay HEFR, & it's associated resistor Z62, and the ETH detector relay HDR. I bolted the left-hand board in place and wired in HOVR, Z23, Z24 & Z69.
Chris & Tom spent four days on site doing various jobs including repairing, straightening & painting the mounting pedestal for the load limiting pot, cabside corrosion repairs to No.2 cab of Repulse, collecting the spare auxiliary gen from Carnforth & taking it to a secure location, continuing to see if a new aux contact mechanism can be made for the reverser for Renown, creating shelving for me in the air filter area of Repulse and various other jobs.
Dave as seems to be the case most weekends at the moment, spent both days doing various jobs, then helped Ian & Pete stretch the stretch bolts on another three power unit big ends on a miserable Sunday when it rained continuously. I wired the auxiliary contacts on BMR1, GFR & OIR relays and the Z59 resistor on the board behind the fuse cabinet in Repulse.
Dave was on site all weekend whilst Steve & Sarah spent Saturday afternoon and all day Sunday there. Dave carried out various work on brake rigging and some bodywork both on Repulse. He also looked into preparing the traction motors for lifting from the two spare bogie sets, I think the fixing bolts are proving very tough!!!
Steve & Sarah continued identifying the cut cables in Renown. The going was very slow this weekend as the cover to the water header tank level switch would not budge so in the end with help from Dave the whole level switch assembly was removed from the tank. Once the whole assembly was removed the cover was prised away to reveal the cable connections. The two level switch cables were identified and labelled. The level switch operation was tested and found to be good and therefore the whole assembly was reinstalled.
A further 2 cables was identified at the Fire Alarm Relay No1. All the cables were retested at the AWS Relay Box to prove we had identified these.
Steve and Sarah took an hour out on Sunday to meet up with John Patrick - Peak Rail Safety Officer to complete their Personal Track Safety certification.
Dave, Chris & Tom spent a marathon five days on site. Dave sorted the spare brake rigging and began cleaning & un-sticking various parts, Tom continued working on the interior wood surrounds on the quarter-lights & drop-lights in 30's No.2 cab & Chris fitted the three remaining sections of 185mm cables to the field divert contactors, as he & I had decided a fresh pair of eyes might be able to devise a solution from pictures he had taken of the cables in 50050. He has also taken the auxiliary contacts off the 'proper' 50 reverser, to see if he can fabricate a new mechanism for the second reverser for Renown & begun cleaning debris from the No.1 end clean air compartment.
Dave spent the weekend on site clearing up the stores shed, then on Sunday helped Ian & Pete stretch 12 more stretch bolts on three big ends on the power unit, having made a new tool during the week. Having forgotten to reconnect the rad fan fuse last week (despite posting that I had completed the wheelslip board), I did so, then fitted the small relay board behind the fuse & mcb cabinet. This board has the Overload Interlock relay OIR, Generator Field relay GFR, No.1 motor blower relay BMR1 and the lighting time switch load resistor Z59. Two of the mounting bolts again required loosening slightly to fit the board in the somewhat tight space, and the resistor was removed to ease fitment. The lugs on the large cables to the GFR & BMR1 were cleaned and they were bolted on to their connections on the rear of the board, which again was time consuming due to the confined space to wield spanners.
Dave spent the weekend on site having a general tidy-up of the coach and container, then helped Ian & Pete torquing the big-end stretch bolts until the tool broke! After I had returned the wheelslip relay board to my house after the previous workparty, I removed the contact fingers from the relays and cleaned them (not the easiest of tasks as the fixing screws are tiny & probably hadn't been removed since the relays were originally made), straightened two of the contact fingers on one relay. They were re-assembled and fitted back onto the paxolin board with new brass cable connection bolts to replace to broken originals, checked for operation by dabbing a 110v DC supply onto the coil contacts and were found to be still working. The associated three 10k ohm resistors were also removed, cleaned, checked with a meter to see they were still working, and refitted. The brass rad fan fuse mounting pillars were missing, so they were taken from the spare broken board, cleaned & fitted. The mounting pillars for the plastic relay covers were removed as they were rusty, & were de-rusted, painted & refitted. The filthy relay covers were cleaned and refitted. Today, the completed board was mounted in the elec cubicle in Repulse, but required a small piece cutting off one corner as some cables that go past the board were hard against one edge, and two of the mounting bolts needed to be loosened as they didn't quite line up with the mounting holes. The board was then fitted and bolted in, the rad fan fuse was fitted & the external connections have been made.
Chris T continued sorting & tidying in both coaches, and applied the 'Smartwater' security stickers to the coaches & both locos, Tom continued work in the no.1 cab of Repulse, Ian & Pete continued fitting the water jacket flexible elbows from the engine block to the cylinder heads, but found two that seemed reluctant to fit, so left them for next time. I tested all the wheelslip resistors with my meter to make sure they were still intact, then removed two, without breaking the mounting bolts, to go with the one I had previously removed, and brought them home to fit to the board I took home last time once cleaned. Chris T thinks he has found a supplier of the Londex wheelslip relays, in case the original ones prove unusable & I will investigate this further. I persuaded the recalcitrant mounting bolts I mentioned last time to align with another relay board's mounting holes with elbow grease and a nylon hammer, test fitted the board, dismantled and cleaned the auxiliary contacts of the relays on said board and started cleaning the somewhat soiled 35mm cable lugs that connect to them.
Dave spend the day cleaning the brake chain & mechanism in the no 1 cab of Renown, Ian, Pete & Chris B removed the 12 remaining fuel pumps to be sent for overhaul & I tidied some more completed cable runs in the cubicle of Repulse, started to bend the fixing bolts for the board mentioned last time & examined the three boards with the wheelslip relays & their resistors. There are three wheelslip relays & three resistors on each board & one board is required per loco. One board seems to have been removed from a 50 rather roughly, as the one corner is broken off where the one fixing hole was, so that one is not usable. The other two boards are intact but someone had tried to remove the resistors before we acquired the boards, and sheared off their fixing bolts level with the boards in the process. Many of the cable fixing bolts for the relays are similarly sheared and can be replaced with brass ones, but the resistor bolts will need further investigation, so I brought one board home to see if I can devise a way to re-secure them.
Tim & Dom did housekeeping duties around our vehicles, then started hoovering accumulated debris from under the cab floors of Renown & the rad compartment passageways. Ian & Pete fitted the last three big end bearing caps into the power unit. Dave started to free off the siezed handbrake mechanism in the no1 cab of Renown and cleaned & painted more cab parts. Now Steve & Sarah have recovered from their car crash enough to be more active, they visited site & I discussed various options with Steve for replacing severed cables inside Renown. They then removed some of the flooring alongside the elec cubicle and by the brake frame & started removing accumulated debris from under the floors. We had a quick look to see if any of the severed cables could be matched with their 'other' ends, and we think we may have identified those to the DSD relays. I test fitted a small relay board inside the electrical cubicle of Repulse, but the fixing bolts need bending a little to bring them back into alignment with the board's mounting holes. I also fitted the Battery Charge Diode. Kev Hand made a surprise visit & returned both reversers he was storing for us, as we are now in a position to permanently fit the proper one into Repulse.
