Not sure if its been mentioned here before but if you like early CIE diesels, this is the video for you!
First 10 mins shows how the IRRS digitized, edited and processed old film and is presented by Ciarán Cooney
The action starts around 12 mins in and shows a down Cork Sulzer 113 ( never see a video of of those before), double A classes, Sulzer's, E class, all the small GMs and amazing rolling stock etc.
Thank you to Tom Dowling, Ciarán Cooney and the IRRS for putting it together and hopefully they will process more for viewing
