Class 3 (Locobase 15978)
Data from "Belfast Central Railway Locomotive [B 68674] = Photograph", archived at the State Library of South Australia, web location [
], last accessed 8 March 2015. Works number was 1707.
Originally bought by the BC for passenger work, this little tank was later adapted to auto-train service on the Great Northern. It pulled trailer cars outfitted to offer 21 first-class seats and 38 3rd class or nine 1st-class and 56 3rd-class passengers. Possessed of good power for the light duty, this auto-train was booked to run between Dublin and Howth (8 1/4 miles) and make 4 intermediate stops in 22 minutes.
