Data from Lionel Wiener, writing in Cassier's Magazine - an engineering monthly (Volume XXXVIII, #5, October 1910), p 470. See also DeGolyer, Volume 12, p. 133. Works number was 7557
This early decapod was typical of the arrangement, but one of the smallest ever built. It had low drivers and a long wheelbase. In the present engine's case, however, that driving wheelbase was reduced to a rigid one of 9 ft 10 in (3 metres) in by leaving the flanges off the 2nd and 3rd set of drivers and adding 1/4" of play to the fourth axle. Combining that short wheelbase with tracklaying that spread the rails 1/2" wider than true gauge allowed this single deck to negotiate curves with a 500-ft radius. At the time of delivery, the train was rated at 3,600 tons on level track. Its operating speed was to be 20 mph (32 km/h). It was out of service by 1907.
