Great stuff. I used Alphagraphix extensively for my Irish OO Ballybeg including their signal cabin, Glenfarne station and shops http://irishrailwaymodeller.com/showthread.php/109-Ballybeg/page16 . I have started working in plastic and may convert some of the railway buildings in time. I am exhibiting Ballybeg for the 10th time at Easter in Wexford. I admire your stamina in showing your wonderful layout in so many venues across the UK!.
Incidently, I lived in Sligo during the 1990's and cycled all over Sligo/Leitrim coming across many artefacts and railway alignments relating to the SLNCR (Slow, Late, Never Comes) railway. What a shame it closed.
