Oeste 4-4-0 Locomotives in Spain
Class Details by Steve Llanso of Sweat House Media
Class 220-2001 (Locobase 3399)
Data from [
] (accessed 7 September 2005).
Passenger design with Belpaire firebox, steam dome just ahead with a crown of safety valves, a square sandbox for the lead drivers, and a small square regulator just behind the tall stack. Bearing the boiler was a heavy, riveted plate frame with an equally bulky riveted leading truck.
According to the site, the first five were originally supplied to the Royal Portuguese Company. This company later transformed into the Madrid-Caceres & Portugal Railway, which in turn was taken over by the Oeste. 2001-2004 went out of service by 1953, while 2005 worked as a switcher at Delicias until 1960.
