American-type mixed-train locomotives with relatively tall drivers, small boiler, and underachieving tractive effort. 207-208 were similar, but slightly lighter. 209 was redesignated H-3 and, when the BAR guide was published, had a slightly larger boiler (1,050 sq ft) and grate (14.5 sq ft) and 63" drivers.
The builders' data comes from a table compiled by B. Rumary based on information from Jeremy Lambert and supplied by Allen Stanley in March 2004. Rumary-Lambert assign works #1596-1598 (September-October 1893), 1617 (November 1893), 1620-1623 (May-June 1894).
In 1907, the class was renumbered in two batches. 13-16 became 203-206 while 17-20 took 10-13 for some reason. 15 was scrapped relatively early in October 1914. 10, 11, and 13 all went in August 1929, 12 followed in December 1930 with 203 being scrapped a month later. All by itself, 204 hung on until February 1941.
American-type mixed-train locomotives with relatively low drivers. Manchester works # 1592-1593 after they received new, smaller boilers in 1919. 211 wound up on the Belfast & Moosehead Lake as their 16 after being sold December 1927.
American-type mixed-train locomotives with relatively low drivers. This second pair of 4 originally delivered by Manchester in 1893 (works #1594-95). Unlike the two shown in Locobase 6001, these apparently didn't get new boilers. Like the 211, 213 went to Belfast & Moosehead Lake again as their #16 in September 1936.
This trio of Americans was rebuilt from a class of 4 Moguls that were originally delivered from Manchester in 1895-1896. Within practically the same wheelbase, the modifiers removed a driving axle and the front truck and substituted a front bogie truck. Also, the heating surface was increased by fitting 25 more tubes in the boiler.
It was a short-term solution as all 3 were retired in 1923-1924. K-2 engines 220-221 were virtually identical. They're shown on the diagrams as having been delivered in 1895 with works # (1545-46) just ahead of the Class A Moguls that provided the basis for the other three. Seems likely that these too were conversions.
