Firstly, my apologies if there is already a thread on this. I've searched back the last year or two and cannot find one.
Just thought that it might be an idea to have a resource thread like this one for news and information on the preserved mainline diesels on the island.
I know that the RPSI have B134 looking like it's nearing completion, B142 awaiting repairs at Whitehead, and B141 and 175 stored at Connolly.
The ITG have A39R and 146 operational at Downpatrick, plus 226 and C231 under restoration at Carrick-on-Suir and Downpatrick respectively.
In storage at Moyasta, they have A3R, 124, 152 and 190, while B103 is stored at Carrick-on-Suir.
A Class number 015, owned by Jackie Whelan, is also stored at Moyasta.
If anybody has any more to add, please do so!
I've linked each loco number to where I got the information, so as of today it would seem to be accurate.
Thanks, @Westcorkrailway.
I had forgotten about the A55 shell at Hells Kitchen, Castlerea.
I didn't include the shunters as I wasn't sure that they were considered as mainline locos.
B113 at the Ulster Folk and Transport Museum, Cultra, is also new to me!
Hunslett no. 102 is also at the Ulster Folk and Transport Museum!
