33110

Used for a couple of minor shunts and 50042 test run see below.

37142

Over Xmas 37142 saw a trip to the engine shed pit for bogie, under chassis, traction motor inspections, cleaning and servicing. Further work has seen an ‘A’ & ‘B’ Exam completed and the two leaking axle box gaskets renewed along with a grease purge ready for the 2017 season start.

With its radiator fan cover in place over the winter, 37142 has stayed relatively dry and fired up Mid-February on a cold day with flakes of snow falling. No issues at all found on a test run to Bodmin Parkway and back.

50042 ‘Triumph’

Triumph was not forgotten over Xmas with a trip down to Parkway shed using 33110, saw us exchange out the old KV10 main generator power control module and fit the newly constructed one.

Whilst two members worked on this, another two carried out parts of an ‘A’ & ‘B’ Exam plus some servicing. Coupling up 33110 to 50042, the latter was extracted from the shed, prepared and started with testing of the new KV10 carried out. Declared working, 50042 was given a work out with 33110 acting as a load, whilst more monitoring of 50042 power handling was undertaken on our 1:40 gradient. The new KV10 replacement works well and early signs are that 50042 is handling power better than it has done since preservation with us at B&WR.

In Overhaul

47306 ‘The Sapper’

There is light at the end of the tunnel as we are again putting things back on 47306 rather than taking them off! This last couple of months has seen a lot of effort going into the Radiator fan grills which open and close slats by hydraulic oil pressure. All four frames have been lowered down off the top of the loco. The first two B side have been stripped down, cleaned back to bare metal, primed and painted, including the many slats. Reassembled and manually tested prior to being installed back over the top of the radiators. The second set of frames and slats ‘A side’ are already progressing and receiving the same treatment.

With the generator out, the whole area underneath has been cleaned, painted and new rubber insulation laid around the cable junction area. Further floor panels have been cut, welded and painted around the engine area completing the floor repairs in the engine room.

Work also continues on repairing exhaust system parts as well as making the new engine room roof strips that the roof sits on and seals.

Cab1 work continues on the wetter days and the head code panel has also now been removed from this end too which like Cab 2 is badly corroded so will probably be replaced.

The news from the contractors that took receipt of the generator set, is outside of the banding starting to come away, the generator is in relatively good condition. It will still undergo a cleaning process, minor repairs, insulation varnishing, baking before being reassembled and returned.

There is of course lots of sanding, filling and painting along with a host of other minor repair work going on. Volunteer man hours of work on 47306 now exceed 3,500 since start of overhaul Nov 2016!

Maintenance for Service Duties

33110

Monitoring of the oil temperature continues but with 33110 now on light load / use with winter work the condition is not seen. Adjustments have been made to the hydraulic temperature valve that controls the radiator fan speed, have also improved the issue.

A second battery cell has failed causing 33110 to only just turn over on start cranking. The cell has been exchanged out with a spare one and 33110 now cranks over correctly.

37142

Following its last turn end of October, 37142 has had a cover placed over the Radiator fan grill to help prevent rain water ingress over the winter. Battery levels checked and topped up plus a topping up charge ready for the winter layup. It is planned to do some servicing work over Xmas and New Year ready for 2017 season.

50042 ‘Triumph’

Likewise post its last turn on the half price weekend at the end of Oct, 50042 was light engine run down to Parkway shed and is now stored dry.

Some tweaking of the radiator shutters has been done to aid the warm up period to be shorter hopefully on cooler days.

Over the Xmas break we are hoping to install the newly built and bench tested KV10 module, if installation is successful then this new module will be commissioned and tested to control the main generator. Once again thank you to those who donated money for this new module which should see 50042 more reliable in the future. A second KV10 module (Yes there is two inside) is also planned to be made and installed when funds allow, further donations to the group most welcome!

P403D ‘Denise’

Is settling in as yard shunter at Bodmin General.

D3452

The class 10 shunter is now awaiting a slot for overhaul. During November the shunter was moved to Bodmin Parkway shed for dry storage by 08444 making it the first time in over ten years that D3452 has been down the Parkway line and away from Bodmin General.

08444

Continues largely in service as yard shunter & Permanent Way duties.

In Overhaul

47306 ‘The Sapper’

It’s now a year since 47306 started its first major overhaul with the Bodmin Mainline Diesel Group, it’s amazing to see what has already been achieved in that time, nearly all by volunteer efforts.

In the last blog update we mentioned we were preparing for the generator to be removed. This occurred in November after many phone calls by the owner negotiating the right lorry and crane-age at the right price for its lift and road trip ‘Up North’. We had to manufacture our own armature support bracket to allow the generator and engine to be separated, a sturdy piece of iron work on its own! The lift itself went well and the weather even gave us a weather window on a very wet and windy day. Meaning the 7.5 ton generator is now away with the contractor being assessed for overhaul.

With the generator removed, working inside the engine room has become a lot easier! Cleaning and scrapping back the generator bed pan has been completed along with painting it out. Most of the internal sides in this area have also been cleaned, primed, undercoated and glossed.

Work continues on Cab 1 inside and out with the inside starting to see the finish post. A lot of filling and sanding has gone into Cab 2 and A side externally, with pink primer for the aluminium cab along with half the A side now in a first coat of anti-corrosion green primer. Work has also been undertaken on Cab 2 roof including making up new aerial base parts that had rotted out.

Work also continues on cleaning and servicing parts of the engine removed so far, rocker covers are all being gradually cycled through a clean-up and repainting. The Turbo is receiving attention as is the parts of the air intake & exhaust system removed, including welding up cracks and facing off the surfaces ready for new exhaust seals.

The Diesel group will be gathering on a couple of days over the Xmas / New Year break, if anyone is thinking of lending us a hand, why not make contact (contact@bodmin-heritage-diesels.co.uk) with us and see when we are going to be at Bodmin General.

Autumn Diesel Gala

This year’s Autumn Diesel Gala was greatly enhanced by the kind offer of Colas Rail to allocate 56078 to transfer from Network rail metals onto Bodmin & Wenford metals via exchange siding at Bodmin Parkway. 56078 arrived at 9pm on Friday evening and then featured on all our Bodmin Parkway to Bodmin General services except the first and last run.

Combinations of our own home fleet 33110, 37142 & 50042 acting as translators (56078 is air brake only and our coaching stock is Vacuum braking only, so our own locos act as braking translators), then solo runs with our own home fleet on the Bodmin General to Boscarne Junction line provide a good variety to the gala day. Listening to 56078 hauling the combined weight of 5 coaches and two home fleet loco's not assisting on our 1:40 gradients is a real treat.

08444 & the recently launched P403D ‘Denise’ also provided two top and tail brake van runs in between midday service runs.

The gala was well attended and enjoyed with much positive feedback received and we look forward to next years.

Maintenance for Service Duties

33110

The on-going engine / oil over heating issue is still under investigation with more observations noted from the autumn diesel gala when the loco was put under higher load conditions.

37142

Outside of the uphill sander valve becoming clogged and requiring a strip down & clean, 37142 has had no issues this period.

50042 ‘Triumph’

Some minor work has been undertaken on Triumph including fault finding the speedo circuit and replacing the circuit card that drives the cab speedo’s. Exchanging out relay PC which after several intermittent faults and attempts to make good still occasionally failed leaving the loco with no traction power. Also all the fire detection heads have been oven heat tested and two replaced to help prevent the false alarms Triumph was suffering from on hot days.

With donations trickling in from a number of individuals either direct to the group or via a justgiving.com (https://www.justgiving.com/crowdfunding/50042-KV10-Appeal)

webpage that has been set up for the purpose. A replacement KV10 module has been partially purchased (Components) and conversion / assembly has begun.

P403D ‘Denise’

After two and half years of on & off work in the B&WR workshops, Denise our Sentinel / Rolls Royce shunter donated by IMERYS (Formally EEC English China Clay) was launched and placed into service on this year’s China Clay day.

D3452

Our Class 10 shunter which is limited to the yard due to issues with shifted cranks, is planned to undertake a period of overhaul shortly. However the shunter has developed both a Vacuum fault and more recently an air leak on the main reservoir air pipe. So D3452 is now failed and awaiting overhaul.

08444

On October the 8th, B&WR opened up its track and sheds for an organised ramble by those who had an interest in seeing up close our infrastructure, rolling stock and loco's. 08444, 33110, 37142, 47306 & 50042 all had visits by interested people climbing up into the cabs and exploring the insides.

After lunch 08444 coupled up with two of our brake vans ran down the Parkway line and back, stopping at Walker Lines and Parkway so further investigation and photographs could be taken of many parts of our railway that is not often seen.

In Overhaul

47306 ‘The Sapper’

The Sapper was briefly shunted to Parkway Shed in late August to allow for the arrival of the new B&WR coach and the turning of the Victorian coach under restoration in a very congested summer station. On its return and with a local contractor signed up, the engine room roof was lifted off for remedial work off site and this is currently underway.

The task of preparing the main generator for removal has also begun, as this too will need to be overhauled by an external contractor to prevent the internal windings and insulation from deteriorating further.

Work continues on the Cabs both inside and out, body work and engine room internals now there is more space. The second electrical junction box that had also suffered badly from water corrosion is in the process of being rebuilt.

The exhaust silencer has received attention from the cutter and welder, along with a full repaint and is now largely complete. The turbo air intake box also is receiving the same attention now.

Total manhours of work on 47306 in the eleven months since overhaul commenced has now exceeded 2,000 by our group of volunteers.

Maintenance for Service Duties

33110

During service (11th June) the Secondman door window detached itself from the metal retainer. This was fixed on the day with glass sealant and service was not interrupted. Another incident however caused some amusement in the cab when the trainee secondman sat down on his seat and set off the foam fire extinguisher that had become lodged under it! The cab had a good and unexpected wash out.

The beginning of August saw issues develop with 33110 and failing to start, this was diagnosed to a single failed battery cell, which was exchanged out for an old (good) spare one. An opportunity was also taken to put 33110 over the steam shed pit once more to look at a couple of spotted concerns that resulted in some more exam checks and sign offs.

For the first time since 1992 and its restoration for preservation service at B&WR, the DSD (Driver Safety Device) has worked in both cabs as missing parts and the system has been made to work! Not essential for B&WR working as we operate with a secondman, it is always nice to know things work as they should and after so long without it though.

33110 completed an A & B Exam before service on the 13th Aug, along with a good external clean so at least we could see out of the drivers and secondman windows!

During service on the 13th Aug it has been noticed that the oil temperature is higher than expected, this is now under investigation.

37142

The booked turn for 37142 on 30th July started out just fine, with 37142 firing up easily at Parkway shed, moving out and completing driver fitness to run checks. Five minutes past this and just at the point of putting 37142 onto the running line for its LE move to General, an air pipe burst under the floor of Cab 2 driver position. With no hope of fixing this on the day, reluctantly we dragged out 50042 prepped and used ‘Triumph’ to haul 37142 to General for repairs before stepping in with our 50 for the day. The location and nature of the failure was difficult and after near two days of combined hard effort, 37142 is back in service again, ready for its turn in September or possibly the ‘Pub Quiz Evening’

50042 ‘Triumph’

Post Engine overhaul and now with some running hours to prove all is well with the power unit since its return to service last Autumn, it was now time for an oil change. Arrangements made and over four days of work, the oil was drained, sump and filters cleaned / serviced. Then 50042 re-filled with the gallons of oil that the 2750 HP engine takes.

‘Triumph’ has been found some summer space in Parkway shed to shelter from the Cornish sunshine and we thought would stay there until end of August for next service. However on the 30th July 37142 failed as above and 50042 covered the service, though proved a little reluctant to leave its cosy shed. Two unexplained engine shutdowns which it is known to suffer on occasions every now and again, each time successfully restarting and continuing with service. Also the Fire Alarms were activated on a couple of occasions as temperature built up internally and the heads are now currently out for testing to find the faulty ones.

The speedo’s in both cabs have once again failed and need investigating.

In Overhaul

47306 ‘The Sapper’

Considerable work has gone into a number of areas of 47306 in the last 6 weeks, in particular all the individual roof panels that have been removed, with then stripping back, repairing and beginning to repaint / restore the fibre glass and frames. The endless task of cleaning back the air filter cages and priming them also continues.

More work has been done around the body sides and cab fronts, with Cab 2 in the process of being taken back to bare metal, enabling us to see all the previous battle damage ‘The Sapper’ has survived over the years. The new head code panel is now fitted and salvaged tail lights are in the process of being reconditioned and painted for fitting.

The renewed control air drain pipe that runs behind the now reinstalled blower motor had a small air leak on its joint when tested. Numerous attempts at fixing this failed through the letterbox hole in the body side that had been cut to assist with this work.

Until it was decided to cut a new hole in the floor and re-run a new union and connection through it. With Batteries reconnected, and 47306 own compressor run up (start governor overridden), created 140psi, all the boiler room repair work was proven to be good!

The BIS (Battery Isolation Switch) overhaul (other than the fibre glass cover) and main bus-bars is fully finished, the task of servicing the batteries and linkage has begun.

The stubbornly blocked rain water drain on the top of the coolant header tank has finally been unblocked by a clever homemade extra-long 5mm drill bit, some 3ft in length! Saving the work of removing the coolant header tank to clear it.

Cab 1 floor renewal has been finished.

A date has been fixed for later in this month for the removal and overhaul by contractor of the main engine room roof. In preparation of this the engine silencer has been lifted out and other parts freed up also ready for removal.

With as many as 10 or 12 volunteers now attending on certain working party days / running days the pace of 47306 overhaul and maintaining the fleet of diesel loco's at B&WR has certainly picked up in the last year or two.

If you think you could be interested in lending a hand then just pop along to the main office and ask for us on a Wednesday or Saturday which is generally the diesel groups working days.
