Belgian State 2-8-0 Locomotives in Belgium


Class Details by Steve Llanso of Sweat House Media

Class Type 33 (Locobase 6616)

Data from [link] (visited 17 June 2005). This site did not have much more to say about the design other than its rated speed was 80 km/h (50 mph).

The illustration shows a noble Consolidation originally designed by Tubize in 1914, but only went into production in 1921. Its bulky Belpaire firebox and Walschaert valve gear--invented by two Belgians-- combined in something of an homage to home-grown engineering talent. The air reservoir was laid over the boiler just behind the capped stack. They ultimately proved too expensive to build and production was capped at eight locomotives.

Locobase was certain that the given value for the grate (1.52 sq m) must be very far off. But a consultation with the tables prepared by Dr Jonathan D H Smith at Iowa State ([link], visited 20 June 2005) confirms the figure used in the specs as a good approximation.
