Kaiser-Ferdinands-Nordbahn 0-4-2 Locomotives in Austria
Class Details by Steve Llanso of Sweat House Media
Class Ajax (Locobase 10717)
Data from "Past and Present Locomotives, Austrian State Rys", The Locomotive Magazine, Vol XV (15 June 1909), p. 117. See also Wikipedia, [
].
This was described in the LM report as the oldest Austrian locomotive then still in existence. Wikipedia identifies it as Ajax and the data show that that presented in LM represented a later rebuilding with a larger boiler. Minotaurus was withdrawn in 1871 and Ajax in 1874, but unlike Minotaurus, Ajax was preserved and restored in 1908.
Class Samson (Locobase 7805)
Data from [], last accessed 27 August 2006.
This was the first passenger locomotive bought for the KFNB. As delivered it suffered from several defects that were fixed or eliminated. The data in the specs refer to the Vindobona after its modifications. A very small engine, the Vindobona left service in 1851 and was scrapped in 1856.
