A trip was made to Whitrope today to take measurements of the timbers with a view to having replacement planking cut.
One surprising observation was that the horizontal planking varied in depth considerably but within certain limits. On the end for example two planks were 220mm in depth whilst another two were 170mm and a single plank measure 180mm. Variations on this them were repeated on each face of the wagons though it has to be said that it still ended up the same total height on every face so the variations ultimately balanced out.
The coach bolts used in this vehicle are pretty badly rusted and it looks like we’ll be grinding these off and replacin
What appeared utterly random though was the floor planking which although of consistent depth had no two planks exactly the same width.
It rather proves an engineer friend’s theory that joiners have somewhat looser measurement standards than those who work with metal!

  1. Two inches seems quite a variation, but it’s less than 1mm on a model! A vehicle of this age would likely have had many replacement planks through the years though and I believe at some point, the railways had their own sawmills; certainly a major wagon works would have had the kit to slice a deal down to a size.

    I also note from your ‘Anatomy’ page that the wagon has self-contained buffers; purely out of intrinsic interest, those will date from the late ’50s when it was vac fitted by BR.

    1. That’s my own suspicion Ian. It does seem from my studies so far that many of this batch were built with vac braking but I note that our vehicle has the underslung pipe associated with 1950s BR refits.
      It’s surprisingly compelling, playing the wagon detective!

  2. The ones originally vac fitted are unmistakable Dave, they have the 8-shoe clasp gear with J hanger suspension. I doubt that many, if any, were built new with 4-shoe vac, despite what ‘LMS Wagons’ may say.

  3. Of course Ian. I only really started to pay serious attention to underframe variations a short while ago and of course our subject no longer has this variant. It all points fairly conclusively to a 1950s rebuild.
    I’m still not sure when this took place (it’s hard enough getting locomotive details after about 1959), but there is a small plate on the sole bar stating ‘repaint due 1966’.
    In which case we’re a bit behind!
