The Tram was part of an excellent "Industrial Tank Engines" pack produced by Michael Whiteley (Now of Mesh Tools) in the very 'early' days of Rail Simulator and unfortunately, I'm sorry to say, is no longer available.
The pack comprised of:-
4 x 0-4-0 Pug's
4 x Avonside Engines
4 x Barclay tanks
6 x J70 (Trams)
All for a modest sum of cash (Ah!, those were the days)
They can just about be seen here through all the smoke at Westhouses Loco Shed.
(Thanks go to Michael and Bob)
