After the standard gauge rebuilt
Locomotive Magazine, April 1893
The Antwerp-Ghent Railway ordered these two locomotives with the intention of later converting them to standard gauge. So they were built by the manufacturer in such a way that the wheels with a gauge of 3 ft 7 in can be removed inside the frame and reinstalled outside the frame with a gauge of 4 ft 8 1/2 in. This plan was implemented in 1899, at the same time the cab was closed and the Westinghouse air brake was retrofitted.
