Restoration diary

Ian & Pete cleared various debris out of the sump of the power unit, and started cleaning & painting sections of inlet air piping. Dave...supervised, as he is still recovering from being under the knife for a hernia and is excused duties for the moment. Mark cleaned & sorted another section of conduit for the generators, to go with the two sections he had previously done, so three down, 13 to go. This is not as easy as it sounds, as most of the lengths of conduits had been separated from each other for easier storage, so it was a case of multiple visits inside Repulse & our stores to find the right sections.

I test-fitted one of the new Z70 resistors, and found it fits the existing brackets perfectly. I just need to properly space the tapping bands, then it can be fitted permanently.

Our gas bottles on the trolley used to collect them; oxygen (black) and acetylene (maroon).

One of those "must get round to doing that sometime" tasks hanging over RRRG has been to collect a couple of cylinders of oxygen and acetylene with which to power our cutting and welding equipment. Although there is a BOC distributor just across the A6 from Peak Rail's Rowsley South site they have limited opening hours which are somewhat inconvenient for the regular on site RRRG volunteers.  Tim and I decided we would head up to Rowsley last Friday night in order to be on site in the morning ready to collect the gas. So, shortly after 4 o'clock on Friday afternoon I hit the road to drive the 170 miles or so from Reading to deepest Derbyshire whilst Tim got a train from Peterborough to Matlock, where I would meet him. I got delayed by the usual Friday traffic whilst Tim got delayed when 66008 decided to investigate the ballast on the Midland main line near Duffield. (I did however make it through Bletchingdon on the A34 without incident after my two year anniversary earlier this month, and once on site, Dave was as helpful and complimentary as ever that my latest car was retaining its factory-fitted styling so well).

The cylinders are now in situ at RRRG headquarters. One of the main uses we will have for them is to heat up some bolts and pins on our spare bogies which are absolutely stuck fast and won't shift any other way.  In particular there are some arms secured by pins and bolts which prevent the traction motors being removed from the bogies and we want to either free these off, or if necessary, cut them off (we have plenty of spares) in order to free the motors for removal to Bowers for overhaul.

Aluminium air intake manifolds destined for the ex-50008 power unit. The foreground example awaits the removal by wire brushing of years of dirt and grime to reach the standard of the background pair, which Dave Rolfe described as "Rolls Royce quality"!

After treatment with the wire brush, Tim and I set about red oxide primer coating of the manifolds we treated that day, as well as returning to some that other RRRG volunteers had already treated, just to ensure that "Rolls Royce finish"!

With the main excitement of the morning over, and after a few steadying cups of tea and brunch at the Peak Rail cafe, Tim and I set to work on wire brushing and red oxide painting of a number of air intake manifolds destined for the ex-50008 power unit. Chris Bodell's nascent music career meant he was playing a gig in Bakewell on Saturday night so he went home to practice and took his leave of us. Tim was diagrammed for transporting teenagers to a roller disco in Peterborough that evening and so, despite building up some momentum on the inlet manifolds, we reluctantly packed up and I drove us the 100 or so miles back to Peterborough, where the teenagers were transported and Tim and I undertook a mutual debriefing session in The Moorhen at Hampton Vale (Tim's local). Sunday was spent doing more work on the soon-to-be-launched new RRRG website (of which more in due course) and I then hit the road for the final time back to Reading, which was covered in a personal best time of 1 hour 50 minutes and brought my mileage for the weekend to a touch short of 400. But it's all good fun (allegedly!).

Sarah and I attended site and again met on site by Dave who I now think lives on site full-time as he is always there :-)

Dave continued with clearing and tidying the container a job that when he started thought would take a morning ended up taking three days. Once this was completed he continued with the refurbishment of the radiator grilles. The process takes such a long take as each element is being stripped back to bare metal, prior to priming and painting, and as BR's policy appears to have been apply new paint onto the old there are numerous layers of paint and a rainbow of colours.

Sarah & I continued with the  assessments of the KV10's. Starting with the best we are checking and cleaning contacts and replacing unserviceable parts. We have finished one complete unit having to re-terminate a couple of broken cables connections and replace a couple of components. The next best KV10 selected had sound looking components but the cable terminations at the top of the unit looked a little rusted and three of them sheared off when attempts were made to loosen them even after liberal application of WD40 (other lubricants are available lol). Therefore we had to loosen of the paxolin board from the body of the KV10 and using recovered termination studs from other scraped units these were replaced but this is not easy as unless you disconnect cables going from one side of the unit to the other side the board only gives finger width space.

Our next visit to site to continue with work on the KV10's will be in a few weeks as we will be participating in a railtour with EE Type1's and a couple of galas where it's hoped to sample a certain Mr Spracklen's 50026.

Myself, Sarah and Toby the dog attended site and the usual weekender Dave was there when we arrived. Dave spent the Saturday erecting a shelving unit the group acquired courtesy of one of our volunteers employers (enough said) and having a general tidy up.

We spent the day working on assessing our KV10's. A couple were found to have damaged PCB connectors, I have found a source for acquiring replacements.

The worst KV10 was dismantled to use a template to check the remaining units and to provide spare parts.

A list of spares needed is being compiled and all parts sourced so repairs can be carried out prior to transporting the KV10's and associated PCB Control Cards for testing.

Following a recommendation from The Fifty Fund I made contact with a Mr Noel Craigen, a former Technical Engineer with experience at various British Rail Traction Maintenance Depots, to assess and test our KV10s and Control Cards.



For those who are not in the know a KV10 regulates the voltage of either the Main Generator or the ETH Generator and are otherwise known as CU3 & CU6 respectively (each Class 50 locomotive uses two KV10 units). Each KV 10 has a pair of Control Cards that need testing and pairing also.



I met Noel at Rowsley on Saturday and we carried out an initial inspection of the KV10's and associated Control Cards. Noel has confirmed prices to carry out electrical and function tests as necessary. Once I have ensured any visible damage or missing parts have been repaired/replaced the KV10s will be transported to Yorkshire to Noel's premises for the tests and necessary repairs  to be completed.

This is another important stage of the electrical and control work underway.
