Hi all, At Dartmoor Railway, we have a Mk1 BUO (Formerly Lab11) that has been undergoing restoration and we have come to a point now where we can start to fit out the Interior. Formerly a BSK, it is now an open layout. Now, all our LHCS is maintained to CMS123 at defined periods set out in our SMS as they are all former BR Stock. Obviously the requirement is for the BUO to comply to this document, however the C&W are in favour of fitting Loose Seating in a 2+1 arrangement around fixed tables (Because the South Devon have done it!?) Would this be allowed bearing in mind the carriage does not have Grandfather rights, and because it is being modified, are there a set of more modern standards necessary to comply to? I don't think just popping down B&Q and getting a couple of cheap sets is going to cut the mustard!! Many Thanks!
