Data from Dr. Jonathan Smith's data tables at [] ... .Works numbers were 27060-27077 in 1952.
Ziel and Eagleson (1973) show this to have been a large switcher and that there were at least 15 in the class. It had long tanks on each side extending from the pilot to the cab.
[] (November 2002), the Nairobi Railway Museum website, tells us that these 4-8-4Ts were converted from 4-8-2Ts using trailing bogies from scrapped Class 50 Garratts. The conversion was a success, says the museum, noting "[The conversion] improved the weight distribution and cured them of their habit of derailing in sidings."
