Restoring the GWR 7200 class prototype steam locomotive

7200 Plays Leapfrog, 6 May 2010

7200's chassis has been moved to the back of the restoration shed in an operation that had it being 'leapfrogged' by a brake van.

Background

Until now, 7200 has been situated in the centre of the restoration shed, with wagons on the track both in front of and behind it. As there is no gantry in the shed, and very little room to position hoists beside the chassis, small items have had to be manhandled onto the chassis; it has not been possible to manoeuvre large items into place.

The decision was made, with the agreement of the owner, to swap the positions of 7200 and the LNWR brake van behind it. This would allow 7200 to be pushed out of the rear of the shed, where hoists and cranes would be able to get access to it.

John Porter's Report

Thursday 6th May was the date for moving 7200 to the back of the restoration shed.

On arriving at Quainton at 9.30am I found that the move had already started, the first job having been aborted due to fears regarding the condition of the coach that was to be turned.

On site were a host of willing helpers, including Working Party Leader Chris Parr and 7200 Treasurer Ian Lodwick. The partially restored LNWR Brake had already been pulled out of the shed, enabling 7200 to hopefully leapfrog it.

Rear bogie being re-railed

As the pull commenced, all seemed to going well until the rear bogie suddenly jumped off the track due to the tight curve, and the fact that, with the bunker removed, there was a dramatic weight loss. The re-railers were called for, and the loco was soon back on the track. It was a rather dejected team who went for a cup of tea and a long hard think.

We thought that we would give it one more try, and decided to try to lift the rear wheels clear of the track. We jacked them up one at a time and, with some help, managed to secure them with a couple of ratchet strops.

LNWR brake van being lowered back onto the track

The large crane then arrived and the LNWR brake was hoisted in the air whilst 7200 was pulled and pushed past it. The brake was returned to the track and pushed inside. It was then a fairly simple matter to return 7200 to the restoration shed and lower the back wheels onto the rails.

This move should now allow for the re-building of the Bunker
