A three-day weekend means an extra day working on the loco!

Today's focus is on preparing the bulkhead in No.2 cab, continuing on from yesterday's relaying of the floor. This is all in readiness to start rebuilding this end, to match the exterior restoration and thus finish No.2 end for now (until final painting).

Railway preservation is a team effort, and often involves the help of other people and organisations to achieve the end goal.

With that in mind, we'd like to take the opportunity to thank Adam and his colleagues at the Welding Centre Ltd in Wisbech for the supply of welding equipment and welding consumables. The Welding Centre has a huge variety of stock and can also source items not stocked. During our visit we were given some excellent information and secured a great deal, making it well worth the trip from Dereham. We are sure we will be back again to re-supply at some point during the bodywork restoration of D6703.

It is this type of kindness and generosity that has helped us all the way through this project and we are very grateful for it!

Time for an update!

Often it's the small things that happen in the background that people tend to overlook when considering the restoration of something as big as a locomotive.

One of our issues early on was the lower cabsides, where water ingress behind the windows had sat and rotted out the body panels.

As built, the locos had drain holes built in to allow water to escape out under the body, but the trays that sat below the scissor frame mechanisms for the drop-down windows had suffered over the years and even those that had been spot-repaired were now showing signs of deterioration.

To prevent future issues, we've fabricated four new trays, complete with drainage holes, and replaced the fixing point for the window mechanisms where these had rotted out. The first of these has now been reinstated, with tubing running through the drainage hole to allow water to pass through the floor of the loco without sitting in the frame (the pipe in the video will be cut back to hide it, the video is simply demonstrating it works!).

This also means that the inside of the driver's cabside of No.2 end can now be rebuilt.

OTDIH - 40 years ago today, 37067 stood in for a failed class 31, on 1M12 1310 Harwich PQ - Blackpool, the type three worked the train from the ferry port to Sheffield, where a 31 took over. The 37 still carried the Thornaby white stripe, from when the loco was based there. This turned out to be the locos penultimate passenger working as 37067, before entering Crewe works for conversion to heavyweight 37/7, 37703. Happily the loco is still in existence at the Paignton and Dartmouth railway, where it occasionally works passenger duties. 37275 is also based on the Devonshire line.

OTDIH - 06/07/2012

In recognition of Dereham's Neatherd High School celebrating its centenary in 2012, the C37LG got involved in the local events to celebrate the milestone by naming 37003 'Dereham Neatherd High School 1912-2012'. This marked the last time the loco saw any notable work on the body done prior to the current works being undertaken, as some TLC was given before repainting the loco from Civil Engineers 'Dutch' to BR blue.

The day saw the name unveiled by both a then-current and an ex-head teacher before doing a short private run to Thuxton and back. The loco was then out the next day on public passenger turns.
