Class Details by Steve Llanso of Sweat House Media
Class 100/060-4021 (Locobase 5509)
Data from [
], the web site of the Spanish National Railway (link no longer active). [] (28 April 2003) reproduces the diagram with all weights and dimensions.Works numbers were 3402-3403 in 1913 and 5365 in 1922.
These later Mallets were still saturated. The first two arrived in 1913, the third joined them in 1922.
