Class Details by Steve Llanso of Sweat House Media
Class N (Locobase 11944)
Data from image 54b of FEPASA website ([
], last accessed 27 December 2010). Works numbers were in the 19200 range.
Bought at the same time as the Moguls described in Locobase 11941-11942, these Belpaire-firebox Ten-wheelers were smaller and less powerful and had straight boilers.
