112 as she was in February 2005. The front end was badly damaged, the paintwork was rotten, scratched and filthy - and there were some worrying hydraulic leaks. The entire passenger rolling stock stands in the closest location to the old 1948 station, which was actually just beyond the fence in the background. Me doing my impression of the Fat Controller. It was shortly after this pictre was taken that we realised the hydraulics were completely shot and would need major surgery.

The good guys at Bredgar gave us shelter and the free use of the workshop. Here 112 has just arrived and is put on a spare 7¼" gauge stand so we could work on it. The body was removed to reveal a multitude of problems, not least of which was a split in the hydraulic oil cooler. The body was put to one side so we could concentrate on the chassis.

Lawrence starts the oily job of removing the hydraulic motors - the pump has already been removed. All motors and the pump were going to be sent off to Hydraulic Pumps UK for assesment. The rear bogie drive chain with one of the worn out Danfoss motors. With the motors and pump away being looked at it was time to start repairs to the damaged front end of the body.

Bredgar's welder, Paul, is one of the best and after I had beaten out the damage he welded up the splits in the seams to try to get some strength back in the body. No explanation needed! After the welding there was a little bit of filling to d before the body was rubbed down, primed and undercoated.

With the motors out of the way the severe grooving on the bogie wheels became apparent. There was little else we could do other than to dismantle the bogies and turn the wheels to lose the groove. Having fixed the axle between centres Lawrence gets to grips with the Colchester lathe.

High Speed turning. Once skimmed the wheelsets were ready to put back into the bogie assembly. There is not really enough meat left on the wheels to skim them much more without causing the loco to bottom out. The reassembled rear bogie.

The body receives the first of three coats of yellow undercoat. The first of two top coats is now applied. With the yellow dry the first of two blue topcoats was now applied.

By carefully laying the loco on its side it was easier to see the bits I had missed. The diagnosis on the hydraulics meant we had to have a new set. This is the new pump which fits fairly snuggly in place! The finished loco just waiting for a couple of finishing touches.

Another view just before its return to the Strand. On shed at the Strand shortly after its return. At Riverside Station.

Finally one of my favourite shots taken at the Par 3 crossing. Not technically good as a picture but it just looks right.
