Netherlands Central 4-4-0 Locomotives in Netherlands

Class Details by Steve Llanso of Sweat House Media

Class Utrecht (Locobase 20079)

Data from "Bogie Tank Locomotive for the Netherlands Central Railway", Locomotive Magazine, Volume 18 (15 February 1912), p. 44.

The short LM article from which the data are taken said little about the design by locomotive superintendent J W Verloops. He noted that it had a Belpaire firebox and the illustration showed an odd side tank profile in which the bottom section curved to avoid the front driver, leaving a long gap along the running board.
