Thanks for prompt replies. Here are a few more pics, though have found most files are too big, so will rest the camera & do a few more over the next few days.
Track is Code 100 flatbottom, copperclad points by Marcway, plain track soldered up by me
The coaches and wagons are all scratchbuilt in plasticard & based on the Alphagraphix kits. Use Slaters wheels, opened up to 5' 3", in either left over W irons from Parkside & Slaters kits [current layout is BR Eastern region, 1950s], or castings from the JPL range. Doubt if the latter are correct, but from photos I have so far, seems to me there isn't the archive material available that we have on English railways [eg any number of wagon & coach books], while Sligo wagons seem to often sport different buffers on each beam/end, so have given up worrying, at least for now.
