This decade of German-built passenger tanks was very similar to the Serie 7 2-6-0s locomotives operated by the AGW at the same time. When the latter were superheated (Locobases 11218 and 11220), they were essentially identical to these 6-axle tanks except for their trailing tenders.
Locobase is not sure whether the Henschels were delivered with superheaters, but given the date, believes that to have been the case.

Just two years after North British delivered the last of the basic Serie 8 Prairie tank switchers, it produced 9 more switchers with bigger bunkers, larger cylinders, and taller drivers. Beyer, Peacock supplied 3 in 1910 (works numbers 5319-5321).
Although rated as switchers, these engines had dimensions that suited them for road-engine duties.
