Data from DeGolyer, Vol 63, pp. 29+.Works number was 56766 in July 1923.. See Locobase 6689 for a description of this railway.
Because this was a coal burner, the CMC could use a straight stack.
Data from DeGolyer, Vol 79, pp. 505+.Works number was 60344 in January 1928.
The CMC had many adverse gradients in its small ambit, tight curve radii of 160 feet (48.8 metres) or 35 degrees, and 50 lb/yard (25 kg/metre) rail,. so the compact and burly Baldwin seemed particularly suited to the task. A note in the Baldwin specifications states that the locomotive was "to operate in both forward and backward positions on 3% grades."
The line linked the mines at Mavrovouni and Skouriatissa to the jetty in the coastal town of Xeros.
One account says that Baldwin supplied four locomotives to the CMC from 1921-1927 (of which this is obviously the last). This was the biggest of the batch.
4 would rust away at Karavostassi for decades after it left service.
