Sultan of Morocco 0-4-0 Locomotives in Morocco


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 10824)

Data from "A Lilliputian Locomotive," Locomotive Engineers' Monthly Journal, vol 22 (1888), p. 128. Works number was 1769 in 1887.

This "lilliputian", as LEMJ characterised it, was the motive power in a gift presented from the King of Belgium to Sultan Moulay Hassan I of Morocco. Accompanied by a mile of track and a passenger coach, the tiny engine displayed some up-to-date materials in order to keep the weight down. One source comments that the Sultan was unimpressed.

The design was packed in by animal so the largest components were designed to weigh only 300 kg (660 lb) each. These were the boiler and the lower frame, although how they were actually placed on the pack animal is anyone's guess.

Cylinders, crosshead, and axle journals were all of phosphor bronze and steel constitutued the structural metal. The wood-burning firebox dictated an American-style spark-arresting stack.
