Agree having had a coffee and a second look at No 6 that is around the 1920s and likely to be from the same time asNo 17 then. Second BCDR photo between 1947 and 1952. Some English enthusiasts came to visit the BCDR when it was listed for closure so will still go for 1949 with the short lived Coaling plant. The GNR photo does look like the shed at Dublin now used by the RPSI.
