Just returned from work to find a wealth of information, thank you very much JHB
You pretty much described my reasons for choosing that prototype
I was actually stuck between modelling the Achill or Clifden line,both quite similar in their origin and short lived lives.
I guess as a general question i've been debating about modelling in 21mm. purely because thats a new area for me. But mabey it's worth giving a try because it would be nice get the broad gauge look. I just wouldn't know where to start, i presume rails have to be bought and sleepers and points made. Is it costly?
Modelling locos and rolling stock i'm looking forward to. We're using 3d printers where i work so this would be a great and fun experiment on pushing my skills in that area. But again, building driving wheels and all the functioning parts seems a bit daunting. But i guess never say never.
Also while ive been sketching and working from photographs the plan is to hopefully take a holiday to that area during the summer, The Greenway itself i've heard is a good enough reason to visit.
