Construction history

The locomotives were built by various manufacturers from 1888 to 1897.[1] The machines had an outside frame with the cylinders and the Walschaert valve gear located inside the frame.[2]

The locomotives used three-axle tenders with 14 m³ (490 cu ft) as well as two-axle tenders with 9 m³ (320 cu ft).[1]
