Brought into service as cross-compounds, these mixed-traffic Ten-wheelers may not have been satisfactory in a number of respects, or the traffic requirements didn't favor a neither-fish-nor-fowl design. .
Locobase supposes as much given that, although all were soon "simpled" with two 20" x 28" cylinders, 6 were sold to the Indianapolis & Evansville in 1910-1911 and the other 4 were purchased by the Canadian Government in 1917.
Locobase 8055 shows the quartet as simple-expansion locomotives.
This was the one Vauclain compound Ten-wheeler that the CGW bought and it featured not only the compounding system but also the Vanderbilt corrugated boiler. (See Locobase 4104 in particular for a description of this unusual vessel.)
220 would later be rebuilt as a simple-expansion engine with 20" x 28" cylinders. In November 1916, 220 was sold to the Algoma Eastern as their class T-1, road number 40. The AE scrapped 40 in 1927.
Firebox heating surface includes 24 sq ft of arch tubes. According to Drury (1993), these were later sold to the Canadian government; see Locobase 8052.
Hearty mixed-traffic Ten-wheelers that duplicated the E-1s shown in Locobase 4162, but that were completed as Vauclain compounds. Like most such engines, these were soon rebuilt by the CGW as simple-expansion engines.
In 1917, the CGW sold all of its Ten-wheelers of this size to the Canadian National Transcontinental Railway and this quintet went along (see Locobase 8052).
Firebox heating surface includes 24 sq ft of arch tubes. E6s 500-501 similar but had more weight on the drivers (151,200 lb).
The pair was scrapped in April 1930 and in 1931.
Firebox heating surface includes 27 sq ft of arch tubes. Piston valves measured 13" in diameter. The first two were heavier than the last 4 for some reason; they put 162,000 lb on the drivers and 216,200 lb on all engine axles.
All were superheated in 1913-1914 and in 1917-1920, the railroad fitted bushings in the cylinders to improve the heating surface-to-cylinder volume ratio. See Locobase 4165.
Firebox heating surface includes 22 sq ft of arch tubes. After those modifications, tube count went to 202, arch tube area dropped to 22 sq ft, and total evaporative heating surface area to 2,457 sq ft. Weight on the drivers climbed to 162,000 lb and total engine weight rose to 216,200 lb. It's not clear how the grate area grew from 46.7 sq ft to 53.6 sq ft.
All of the class was scrapped in March-June 1950.
