Data from DeGolyer, Vol 63, pp. 313. Works number was 52500 in November 1919.
Like many small plantation saddle tanks, this little wood-burner had a Rushton Improved spark-arresting cabbage stack.A "hereafter" note in the specifications tells us that the Barahona requested that all future locomotives would be equipped with Walschaert vavle gear.
Data from DeGolyer, Volume 63, pp. 313. Works numbers were 53411-53412 in July 1920 and 53887 in October 1920.
Built as wood-burners, these little saddle tanks were to be easily converted to oil-burning. All had the Rushton Improved spark-arresting cabbage stack.
Like the earlier 0-4-0ST shown in Locobase 14779, this entry had a "hereafter" note that requested that all future locomotives would be equipped with Walschaert valve gear.
