Could the 24' tubes have been the original length but soon seen as overwhelming both the fireman and his grate without any commensurate gain in heating value? The tube count certainly suggests as much. The two earlier accounts showed 446 tubes and a total of 6,629 sq ft of heating surface. A later 1907 AERJ raised the tube count to 468, but shortened the length to 21 ft (total ehs 6,108 sq ft). In the June 1908 account of the testing, we see still fewer tubes and a lower overall heating surface area.
Known at one time as the Angus, they were the only camelback Mallets of this wheel arrangement. Drury (1993) comments that "On the job they proved mostly that it took a skilled and strong fireman to produce the power they were designed to deliver."
In 1921, they were rebuilt by Baldwin as 2-8-8-2s; see Locobase 7745.
In 2004, MTH modelers unveiled its model of the 0-8-8-0 and explained the nickname as follows:
"The L1 obtained the nickname "Angus-type" as a result of noted railroad operations writer Angus Sinclair's comments that the L1 would dry up all the country's canals and make all forms of water transportation obsolete thanks to the engine's incredible thirst. Because only three L1 locomotives were constructed, Sinclair's comments never rang true but the engine did establish the use of Mallet type engines beyond narrow gauge light duty use."
