Purchase from Rodney Group

RRRG has just purchased a traction motor, two compressors and an electrical cubicle (all ex-50011 Centurion) from the 50021 Rodney group/ owners . The items will be collected, together with items bought by the D400 fund, and transported to Bowers Electricals Ltd. at Heanor for assessment and any work that may be needed.

The  electrical cubicle that has quite a few re-usable components will be dropped off at Rowsley where the parts will be stripped for future use or spares.

Another CU1

Back in 2002 when RRRG successfully bid and secured Renown and Repulse together with various spares David Phillips was a volunteer at Pontypool & Blaenavon Railway and safely stored a CU1 on our behalf. As Sarah & I were travelling down to Swanage diesel gala this weekend to enjoy recently restored 50026 it was decided to call in to David's home in Trowbridge to collect the CU1 en-route. Whilst there I received a bonus in the form of an Ammeter for one of the cabs. I would like to thank David for safely storing the parts and also for the hospitality he and his wife offered us.

Updated share certificates

RRRG investors who have earned shares through work parties or purchased additional shares, up to the end of June 2011 will shortly receive an updated share certificate.

The date of end June is chosen because, for historical reasons, this represents the end of the RRRG financial year and so any shares obtained after this date will NOT be counted in this update. Only shareholders whose shareholding level has increased by one or more whole shares will receive an updated certificate - put simply, if you haven't acquired any more complete shares since the last update then you won't get a certificate this time round!

Anyone who thinks they should have an updated certificate but hasn't received one by the middle of next week, please get in touch.

Work Party 28th April 2012

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.

Work Party 21/04/2012

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.

The two KV10 boards removed.

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.

WorkParty 14th April 2012

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.

Nene Valley sales stand stock logistics

After work on the evening of Monday 2nd April Mark and I drove miles and met up off J18 M1 to transfer more stock to me for the Nene Valley Railway Tornado and Thomas event. We have accumulated a lot of steam and generic railway stock over the years and beefed up our toy offering so I saw this as a great opportunity for RRRG and the Nene Valley Railway were happy for us to attend and publicise our attendance.

We also spent an hour discussing a number of RRRG challenges.

Another long drive partly through some new roads to me around Naseby on a pleasant evening saw me somewhat tired but managing some attention for Jack the dog and Frankie and Bella the rabbits before bed to be fresh for the commute and work tomorrow.

Work on site 1st April

I found another 10-12 conduit and pipe clamps that I need for in the generator room. I cleaned these up with wet and dry sandpaper and a wire cut brush, then white spirited them and painted them. Also put another coat of paint on the 40-odd clamps that I did last time I was on site.

I also re-secured 50029’s tarpaulin which was loose and flapping around a bit on one corner.

Dave Rolfe was on site as usual and continued with painting a second coat of paint onto the radiator grilles.  I took a few photos and noted how good they were looking; we will share these here soon.

Workparty March 25th 2012

Dave was on site all weekend working on cleaning and painting one of the bodyside radiator grilles.



Ian and Pete with some assistance from Dave continued working on the ex-50008 engine replacing some of the head covers.



Steve and Sarah assessed traction motor contactor arc-chutes so spares and paxolin to replace missing parts can be ordered.



The long process of verifying all the cables from the electrical cubicle to equipment in 50029 was started. Each cable was to be tested with a multi-meter to confirm continuity. The first cables checked were those from terminal bar TB6 with blower No1 cables testing out ok. Problems were then encountered as we checked Blower No2 but could get no reading and eventually realised this was because the cables and flexible conduit had been cut about an inch from the connection box.



As it is too difficult to pull any slack through we have decided to dismantle the conduits with a view to reinstalling via a shorter route up the front of the blower negating the need to replace the cables.

Workparty report for weekend 17th & 18th March.

Tom prepared the cab vestibule at no 2 end for repainting and carried out repairs to ceiling trims. new cab light frames were cut and replacement lights fitted.  Chris unseized the bolts securing the rad fan ducting to the fan motor and freed off the rad fan securing nuts. Doesn't sound much but all are captive and rusted solid so needed considerable work to avoid shearing and drilling out later.

Tim & Dom continued buzzing the surface rust and grime off the brake rigging that had been selected by Chris and Dave for use on the bogie overhauls.  The pile of "to do" components is now virtually nothing and Dom got a very nice facial treatment out of it as well, after which he discovered the shower in the Peak Rail shed is stored unserviceable. Tim took to the bits of rigging Dom had done to clean the areas he couldn't reach, using a drill as opposed to the wire cup brush Dom had. Following this and an unexpected appearance by Chris Bodell the two of them dragged the cleaned-up rigging to join the rest of it in an undercover location.  There they sprayed the pieces with light oil in order to preserve them until we start reassembling the bogies.

I only attended on Sunday, and with the length of the committee meeting, I only had time to fit the last missing shaped copper bar I had made, which goes from the reverser to no.2 traction motor contactor.

KV10 news

Preliminary discussions have been engaged in with a good contact who can overhaul KV10s.  RRRG has a good number of both KV10s and their control cards in our possession but we have no idea if any or all of them are actually serviceable!  For the uninitiated, a 50 has two KV10s: one controls the main generator field strength and the other the ETH generator field strength - the difference being the control cards in the KV10 which define its function (main or ETH generator).  We understand this same contact can overhaul CU1 control units (the "master brain" of a 50) and we hope to have more news on these electronic component overhauls in a month or so.

On site activity 25-26 Feb

A good attendance this last weekend, others will contribute their own reports in due course. New volunteer James Andrews arrived on Saturday for his first working party and we were also blessed with the presence of Paul Sturm on an impromptu trip from the Netherlands. Dave Rolfe was the usual permanent fixture on site as Tim and I arrived at about midday on Saturday. Later on Sunday we were joined by Mark Burrows, Ian Kemp and Peter Carter.

Tim, Paul and I concentrated on the continued cleaning of brake rigging equipment where a large stash was extracted from storage:

Although not in the "Chris Thorn" level of restoration skill the wire brushing of these took much elbow grease and many cups of tea and ready meals during the day. The gradual accumulation of brushed parts into a pile for Tim to hone with the smaller drill was quite satisfying:

Brake rigging cleaned with large wire brushes by Paul Sturm and myself, ready for Tim to hone with the smaller drill.




Meanwhile Dave and James had removed one of the adjustable radiator louvres from 50030 with a view to getting the shutters to work again. The linkage was seized utterly solid and heavily rusted. However Paul brushed it up and when Ian arrived on Sunday their combined efforts made for an amazing transformation:

The rusted, seized radiator linkage after brushing up by Paul Sturm and treatment by Ian Kemp with a little used engine oil.




Elsewhere, Dave, obviously heartened by the success on one radiator grille, removed the other one for similar treatment (but did reinstall it before the end of the weekend).

All in all this was a very productive weekend and I look forward to the next working party.

Confessions of a Workparty Virgin - 25th February 2012

I have to confess to have been a lapsed 50 fan for 25-odd years, I last saw Renown in January 1986 on a Waterloo – Exeter service and Repulse in August 1985 on the lengthy Scots Streaker II Railtour. It had been too long. I have recently “come back” and joined RRRG, and in late February finally joined a working party. After a few dead-ends in the sprawling Peak Rail site, I eventually tracked down the locos and it was great to see them again after all these years, although sadly quiet for the time being.

Dave greeted me with the immortal words “Have I got a job for you!”, and, having shown me round and letting me linger for a bit around Thunderer’s 16CSVT, we set to work removing the bolts holding in the louvre grills at No 1 end of Repulse. It wasn’t clear if these had been removed at refurbishment or never at all, but they were a job! While we were working through these, Dom and Tim arrived along with Paul Sturm, fresh off the ferry from the Netherlands. They tackled cleaning up the brake rigging gear while we slowly but surely removed the bolts. In classic tradition, the last bolt followed form by thinking itself completely invincible, being not only firmly stuck but also seemingly utterly inaccessible. After lunch and a fortifying mug of tea though, we were on a roll and spitting defiance finally got it out, allowing the frame containing all of the (very jammed) louvres to be taken out and gently lowered to the ground. In no time, they were freed up and moving again, and the upper louvre re-aligned to match the others – cracking job! The very corroded arm which should open and close the louvres was also removed – it looked like to have been under the sea for years and I thought it was beyond hope, but Paul and Tim brought it back to life with a bit of grinding and a diet of engine oil.



I had to return home in the evening and so missed the beers and curry, but what a superb day – up close and more personal than I ever imagined to Renown and Repulse (they’re bigger than you think from ground level), and a feeling of complete satisfaction at having contributed something real (albeit miniscule) to getting them back up and running again. Looking forward to my return, and thanks to Dave, Tim, Dom and Paul for putting up with my general clumsiness and endless questions. And they never even sent me for a bag of steam or striped paint once…..Thanks guys!

Workparty report Feb 19, 2012

Dave spent his usual weekend on site, this time removing pipework in no.1 end clean air compartment to allow it's cleaning & refurbishment. Ian & Pete are currently reassembling power unit valvegear & fitting cork gaskets between the various cylinder head covers. I fitted a missing copper strip between two of the rad fan contactors. I had had a suitable piece for some time, but needed to copy the mounting holes from another 50, so copied it from the same piece in Thunderer. I also hunted out & found a copper busbar I had retrieved some time ago from a scrap 31 to cut a piece from the reverser to no.2 motor contactor. I also found a suitable piece of Paxolin board from our stock to cut pieces for the rad fan electronic unit we are having made for us. As Ian and I missed the pre-Chrismtas curry due to the weather, after we finished at Rowsley, we went for one at the Maazi in Matlock, and very nice it was too, but yours truly had a coughing fit when some mint sauce went down the wrong way & frightened the waiters.
