This immense undertaking was carried out by daily steam-operated workings that consisted of specially constructed side-discharge hopper wagons, powered by 2-6-4 tank locomotives, known as 'Jeeps'.
These workings were the last commercial use of steam traction in Northern Ireland and the last example of revenue-earning broad-gauge steam operation in Great Britain.
Other parts of the Northern Ireland rail network also feature, including:
The line to Londonderry
Scenes at Belfast's York Road Station with Beyer-Peacock built 0-6-4T 'Lough Erne'
Plus the 1970 'Colmcille Railtour' headed by ex-GNR 4-4-0 No. 171 'Slieve Gullion'.
