Alf~ld-Fiumei Vas+t/ Hungarian State 2-4-0 Locomotives in Hungary
Class Details by Steve Llanso of Sweat House Media
Class 1 / IIm / 237 (Locobase 11202)
Data from [
], last accessed 13 April 2010. Three builders contributed locomotives to this class: Maffei (18 - works 688-705 in 1869), Krauss in Munich (10 - works 49-58 in 1870), and Sigl in Wiener Neustadt (10 - 1152-1157 in 1870, 1260-1263 in 1871). (Production data from [])
These engines apparently opened the AFV, which ultimately extended for 397 km (240 miles) and included the cities of Gro+wardein, Essegg, and VillányAfter 10-15 years in service, the class went with the AFV into the Hungarian State system in 1884 and renumbered. In 1891 they were designated IIm and renumbered 1222-1259.
After World War One, 6 went over to the Romanian State Railways and the others were all retired by 1924.
