Chicago & Erie / New York, Lake Erie & Western / Erie & Wyoming Valley / Erie 4-6-0 "Ten-Wheeler" Type Locomotives

Class G-000 (Locobase 390)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Lone camelback originally built for the Erie and Wyoming as engine 222. Bought by Erie System in 1906 and renumbered. It's not clear why this one locomotive would not have been counted among the G-14 class (Locobase 403). There's a minor 8-sq-ft difference in heating surface area ...

Class G-10 (Locobase 399)

6 engines that were virtually identical to G-2s, but rode on 68-in drivers. Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Class G-11 (Locobase 400)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

12 engines built one year before very similar G-1s and designated retrospectively.

Class G-12 (Locobase 401)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Considerably larger than earlier Erie ten-wheelers, these Cameback Ten-wheelers had greater tractive power. At the same time as these were delivered, Baldwin supplied Vauclain compounds to the same design; see Locobase 402.

The G-12s remained in service until 1927.

Class G-13 (Locobase 402)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection,.

15 camelback engines built as Vauclain compounds in the same year as the G-12 simples (Locobase 401); they had identical boiler and grate dimensions. Later rebuilt as simple-expansion engines.

Class G-14 (Locobase 403)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

12 small Ten-wheelers built by Dickson and Baldwin. First with large Wootten firebox and thus camelback locomotives. Indeed, because the boiler was so small, this design had one of the lowest heating surface/grate area ratios of all -- 15.5. These snub-nosed 4-6-0s had boilers that were short even for the double-cab arrangement. And the diagrams suggests that the firedoors sat on a level with the cab, which must have offered a more-than-usually frightening prospect to the fireboy who straddled the footplate and tender plate to heave birds-eye and bituminous culm in a relatively small Wootten firebox.

They were not retained as long as the other camelbacks, in part because of their greater age. Most were scrapped in the early 'teens.

Class G-15 (Locobase 422)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Last ten-wheelers built for the Erie; operated as passenger engines. Like many other engines of that time, they were later rebuilt with piston valves acuated by Walschaerts gear and fitted with superheaters. They lasted until the 1940s, with the last one retiring in 1951.

Class G-15 - superheated (Locobase 9240)

Data from Westing's Erie Power (1970) and Erie 7-1949-1 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection. Firebox heating surface area included 2 arch tubes that contributed 13 sq ft.

The Susquehanna shops rebuilt these Ten-wheelers. 11 received Walschearts, 14 Baker valve gear to drive their 12" piston valves. Although 970 was taken in hand in 1915, the others were updated in the 1920s with a useful amount of superheat without the sacrifice of too much heating surface. By that time, too, master mechanics realized they could gain even more benefit if they kept the boilers set at the original saturated-steam level (usually 200 psi) rather than dropping the pressure.

Class G-16 (Locobase 405)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These camelbacks were delivered as G-13s (Locobase 402), but later rebuilt to these dimensions.

Class G-3 (Locobase 393)

Data from 1899 Brooks Catalogue and from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection. (the 1907 book is used for the firebox heating surface and overall EHS).

40 engines built by Brooks, Cooke, Richmond, and

Rogers--all later part of American Locomotive Company (Alco).

According to a compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers were 2355-2359 (September 1896); road #780-784. Brooks numbers (also from a Rumary compilation) were 2693-2697; road #770-774

Dimensions, demand factors, and ratios are "modern". Physically, these were tall engines with beehive steam and sand domes; much greater spacing between second and third axles than between first and second. They retained outside slide valves and an inside valve motion.

Class G-4 (Locobase 394)

Originally built as 8 compounds with dimensions very similar to the G-2 simples. High-pressure cylinders were 14 inches in diameter, low-pressure diameter was 24 inches. Rebuilt as simple expansion engines from 1904-1905 (and 1907) with dimensions as tabulated. Some data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection,

Class G-7 - simpled (Locobase 9232)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Rounding out the basic G-6 design (Locobase 9231) from Baldwin in 1893 were these two engines (works 13679-13670) delivered originally as 4-cylinder Vauclain compounds. The HP cylinders measured 14 1/2", the LP 25" in diameter. Eleven years later, they were converted to the simple-expansion layout shown in the specifications. In the process, they became marginally more powerful than the G-6s.

Both G-7s were scrapped in March 1924.

Class G-8/G-9 (Locobase 398)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

50 engines built by Susquehanna shops and Baldwin in 1891 and 1896. Note very large grate in this camelback design, used for burning low-calorie coal. Most were simple-expansion, some (possibly only 975) were built as compounds with 14-in high-pressure, 24-in low-pressure cylinder diameters. Compounds worked at 180 psi.

Class O / G-1 (Locobase 391)

41 engines built between 1889 and 1893 at the Erie's Susquehanna Shops and by Baldwin.

Class O / G-2 (Locobase 392)

8 engines similar to G-1s, but with smaller drivers, slightly higher demand factors. Built in 1893-1894.

Data from Westing's Erie Power (1970) and tables in December 1894 American Engineer and Railroad Journal (AERJ) and from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection, There's a 40 sq ft discrepancy between the AERJ number (shown in the specs) and the 1907 book. One may count the arch tubes, the other may not.

Class O / G-5 (Locobase 395)

20 engines built 2 years before G-2 or G-4. Engines 700-707 were later renumbered as engines 720-727.

Class O a / G-7 (Locobase 397)

Data from Westing's Erie Power (1970) and tables in December 1894 American Engineer and Railroad Journal (AERJ).

2 compound engines built to G-6 dimensions, but provided with 14 1/2-in diameter high-pressure and 24-in low-pressure cylinders. Rebuilt as hard-worked simples (note demand factors of small boiler and grate) in 1904 and 1905. Renumbered 976 and 977.

Class OA / G-5 (Locobase 9230)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Typical early-1890s Ten-wheeler of relatively modest dimensions and boiler pressure.

Class OA / G-6 (Locobase 9231)

Data from Erie's 1907 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

This Ten-wheeler sextet is described as the Oa class "half deck" in the Erie diagram book. A comparison of the diagrams for the G-5 of two years earlier (Locobase 9230) and this set shows that the structure in the cab extended to the rearmost post in the earlier locomotives but were cut short (by half) in the G-6. The firebox has a somewhat smaller grate but quite a bit less firebox heating surface.

Class Oa / G-6 (Locobase 396)

6 engines originally built for the Chicago and Erie and numbered 330-335. Note the small grate area.
