D1013 B Bogie Update 30.06.2025 by Graham Gant.
Details of work carried out so far during 2025 follows –
Bogie Frame
The main objective at the start of 2025 was to get the top surfaces of the Bogie framework ready for NDT Inspection (Dye Penetrant Inspection) of weld joints. Photos show the level of scraping and cleaning required. NDT was carried out on 5th February by Applied Inspection, no defects found. This enabled the team to apply Red Oxide primer followed by Chassis Black to all areas that had been prepared.
Brake Rigging
All the Brake Rigging has been scraped, cleaned and had a coat of Red Oxide primer and Chassis Black. Some of the Rigging has been refitted temporarily to facilitate movement of the Bogie at a date to be confirmed.
Intermediate Gearbox
This has been scraped clean, washed down and had a coat of Red Oxide Primer and Chassis Black applied.
Inspection of the Oil Pump has still to be completed.
Equalising Beams
Also on the 5th February the Central Pivot weld of 2 off Equalising Beams were NDT Inspected (Dye Penetrant Inspection), no faults found.
These 2 Beams were then moved back to Bridgnorth for the ‘Top Hat’ bushes which are pressed onto the Central Pivot to be fitted. During this process it was noted that one of the Beams has a straightness issue which is going to need specialist attention by a sub-contractor.
The remaining Beam along with another Beam will be going for welding of the ‘Top Hat’ bushes during July, again a sub-contract activity.
The new Pedestal Brackets have had new grease pipes manufactured and fitted by our colleagues at the Severn Valley Railway (ESMP Department). The Brackets have then had a coat of Red Oxide primer and Chassis Black applied.
During March 2025 the long awaited new Spring Hangers (17 off, don’t ask) were delivered. 8 off have had new Spherical Bearings pressed in and now await the Equalising Beams before fitting can commence.
Brake Cylinders
During May 2025 we took delivery of 42 off new Brake Cylinder Seals courtesy of our friends the DTG who had purchased a batch for themselves, us (WLA) and the DEPG.
The Brake Cylinder stripping has commenced, surprisingly the internal condition of those stripped to date is excellent and no additional work is required. (Last overhaul 2002)
Thrust Brackets
Both the Front and Rear Thrust Brackets have been scraped and cleaned. The Front Bracket Thrust Pad Manganese Liner has a cracked weld, this will require the attention of a specialist welder. As previously mentioned in an earlier update the Rear Bracket requires a completely new Thrust Pad. A Purchase Order has been placed for a small batch of new Thrust Pads, both Front and Rear, these are due for delivery in July. Once received they will require the attention of a specialist welder to attach new Manganese Liners.
On 17th May (Diesel Gala Saturday), D1013 was placed on the Jacking Area in the TMD and the Jacks positioned to carry out a lift, unfortunately due to a technical fault with the Jacks it was another 2 weeks before the lift took place.
The Thrust Brackets were bolted and clamped in place to their respective positions of the Underframe. Our colleagues from the SVR ESMP Dept. have reamed out all the existing holes and manufactured new Fitted Bolts, this is a procedure which was carried out when Class 52’s were in revenue earning service with BR and an official BR drawings exist for this work.
Air Piping
This has been scraped, cleaned and had a coat of Red Oxide primer and White Gloss paint applied.
A end Bogie
Work to remove years of baked on brake dust, grease and grime has commenced on the underside of A end Bogie whilst D1013 has been on the Lifting Jacks, this is required to enable NDT Inspection of Bogie Frame welds from below to be carried out.
D1013 is now back on the DTG accommodation bogie as at 28th June 2025.
