Putting the Block on

Tuesday 16th May

Four of us off to Broadway today to advance some of the work on the signal box.
As we were departing from Winchcombe we were held up by a departing wagon (presumably for Sharpness)


And last week a tube wagon being winched onto a low loader


The main task today was to mount the Block Shelf in the signal box. The two original brackets were too short and have had extensions welded on - they now needed to be cut to length after trying in position to get a suitable gap between the shelf and the top of the levers. The Transit doubled up as a workshop to do this:



First of all we had to hold the brackets in place and mark the hole positions in the roof beams and drill 2 holes  - a bit of an acrobatic performance because the roof is quite a height



  




Then to drill the holes in the Block shelf to match the brackets



Have we got the gap right?  Looks OK to me




Leaning- on test discovers that there is a significant lateral movement. A central horizontal bracket needs to be made and will be fitted to prevent this. Also a hollow pillar will be fitted for centre support  - this will double up to conceal the wiring. Otherwise it looks the business.






Meanwhile down in  the Locking Room Malcolm was wrestling with the fitting of the remaining connecting rods for the point operating levers. The ones we had were not the correct length so they have been shortened and re- welded  ( courtesy of out C&W colleagues) . They connect the lever tails to the angle cranks. Further rodding will then reach through the tunnel to trackside. Here's the top  connection



And here's the bottom





Fitting the split pins to retain the pivot pins in the lever tails is a very fiddly job . Malcolm managed it after uttering a few choice words




It was a relief to have a day off from cleaning  the dreaded point rodding today. Four of us have signed up for the grand rail  clipping at Little  Buckland tomorrow.

  1. Great to see the block shelf going in, and also the rods for the point levers. Looks wonderful and a lot cleaner than I expected. Good work. Regards, Paul.
