Class Kg (Locobase 1518)

Data from "SEK class Kg" in Wikipedia at [link], last accessed 3 October 2022; and A E Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot, Devonshire: David & Charles, 1966), p. 52, 60 See also thread begun by christo on 4 April 1914 at [link]

Most sources report that four Belgian locomotive companies supplied units of this class. But the SA St Leonard's order of six locomotives for the HR fell victim to a dispute over the order's fulfillment. Instead, those six locomotves, which had already been assigned works numbers by St Leonard, came instead from the Haine St Pierre, as shown in the table below.

Part of a large ten-coupled stud no doubt assembled to tackle Greece's mostly mountainous terrain, these were the only class that did not have a leading truck. In the Balkan Models forum, jsimantof's 24 April 2014 contribution included this unusual comment: "Just to add my ritual anecdote, those engines had a strange feature: the reverse lever was mounted in a very strange position, so that when the lever was put forward, the engine went backwards (!!)."

Locobase wonders if this was the only HR class in which this was true.
