This last week has seen the removal of the parts used to hold the front frames in position. The outside of the frames have been cleaned up and a coat of red oxide applied, apart from the weld area which will be subject to an NDT test before being painted.
The front frames
The front bogie mounting plate has been receiving attention. This was separated from the stretcher on which it is mounted, the corrosion which had built up underneath it was cleaned off and the whole area painted with red oxide paint.
Here Nathan is seen working on the plate and mounting point, the whole assembly is upside down.

Attention has now turned to the rear frames, these will also need to be cut and replaced.

About the Trust
Work on the overhaul of 5025 began at the beginning of 2012. This was thanks to grants or promises of support from the Strathspey Railway Company, the Strathspey Railway Trust, the Heritage Lottery Fund the Strathspey Railway Association and the significant amount which had already been raised from our supporters though appeals.
Major progress has been made on the locomotive and tender frames, axleboxes, motion, dragboxes and valve gear at Aviemore and on the major rebuild of the boiler, reprofiling of the tyres of the locomotive and tender wheels and construction of a new tender tank at Riley Engineering of Bury. Work has also included the casting and machining of a pair of new cylinders
The WEC Watkinson Trust originally hoped to return 5025 to service in 2015, however owing to the amount of work needed, a more realistic aim is for completion is towards the middle of 2018.
To achieve this further donations to the WEC Watkinson Trust will be welcomed by our treasurer: WAD Macphail CA, ‘Ardneil’, 80 Bruceland Road, Elgin, Moray, IV30 1SP.

21.06.2006, 5025 stands outside the shed, being prepared for its annual visit to the steam fair at Boat of Garten.
Another view taken in June 2006.
Following a period of preparation, dismantling started in February 2011, above and below the cab roof is about to be removed.
The roof comes away.
Moving on, the next stage is preparing for the boiler lift.
This past week has seen the welding in place of the new front frame sections.
The picture below shows Jack removing the cross members and smoke box saddle. These had been put in place to help hold the frames in position whilst they were welded, this helps to avoid distortion. They are being removed to allow the weld to be subjected to ultra sonic testing, following which the frames will be cleaned up, painted and generally made ready to received all the parts which are bolted to them.
Below; a close up of the weld which has been ground back to the level of the surrounding steel.

During the dismantling stage, the smoke box saddle fabrication was found to be badly corroded in the centre. In order to remove the saddle, the cylinders had to be removed first, as the exhaust ports on this early version go through the frame and the saddle. When removed, the cylinders were found to be in need of replacement as they were both cracked horizontally, as well as being badly wasted. The front frames behind the cylinders were also found to be badly corroded and a large section has had to be replaced.
This picture was taken during July 2012, before the front end was dismantled, the smoke box saddle can be just about seen.
This picture shows the cut where the front of the frames have been removed

The assembly being lifted into position
Another view from the opposite side, shortly after this picture was taken, the whole from end assembly was lowered to the ground and picked up again in a more horizontal alignment.
The repaired smoke box saddle fabrication, this will be dropped into the centre of the front frames prior to welding to help with holding the frames in position.
