Data from 1912 Railway Gazette of 7 December 1912. See also Patrick Skinner, "When Cyprus had Railway Trains", Financial Mirror (Cyprus (2 November 1916). Boiler pressure is an estimate.
The article notes that the CGR opened in 1905 and had by 1912 opened 61 miles of single track on which rode 39-lb/yard (19.5 kg/metre) rail. Its ruling grade was 1% (1 in 100).
These two American-type Eight-wheelers handled the passenger service and had relatively tall drivers. Surviving depression and war, the 11 & 12 ran until 1951 when the 762-mm line closed. In his account, Skinner wrote that the railway operated passenger and freight services daily from October 1906 to December 1951. The system offered 39 stops including such "commercially important" towns as Famagusta, Prastio Mesaoria, Angastina, Trachoni, and Nicosia. Freight operations included transfer trains at the port of Famagusta, timber trains" from the Trooos Mountains to towns and cities across Cyprus, and the carriage of freight, ore and minerals for the Cyprus Mines.
By that time, they had been converted to oil-firing.
