Data from "Illustrated Interview. Mr Ernest Albert Prosser, General Manager, Rhymney Railway", Railway Magazine Volume 26, No 1 (January 1910), pp. 1-11, table on p. 9 . Works numbers were 1289-1293 in 1890.
Locobase struggled to find any information about this small class passenger saddle tanks. These were deemed too small for passenger work before too long and were relegated to shunting duties.
65-66 were absorbed by the Great Western in 1922 and retired in 1928.
