Erie 2-10-2 "Santa Fe" Type Locomotives

Introduction

The first "Santa Fe" type locomotives to arrive on the Eire Railroad were two that came in 1915 and were part of an order of forty-two locomotives the Erie gave to the three leading steam locomotive builders of the day. The forty-two 2-10-2s were designated as Class R-1 and were assigned road numbers 4000 through 4041. The Baldwin Locomotive works built nineteen, the American Locomotive Company built fourteen and the Lima Locomotive Works built the other nine.

These class R-1s had 63" diameter drivers, 31" x 32" cylinders, a 200 psi boiler pressure, they exerted 82,982 pounds of tractive effort and each weighed 429,300 pounds. The firebox heating surface was 126 square feet of thermic syphons and 20 square feet of arch tubes. Another variant had no thermic syphons and 37 square feet of arch tubes. The total firebox heating surface amounted to 358 sq ft and total heating surface came to 5,684 square feet.

Also in 1915, some of the thirty "Santa Fes" that the Erie bought from the American Locomotive Company began to arrive. The group was designated as Class R-2 and was assigned road numbers 4100 through 4129. These locomotives had 63" diameter drivers, 31" x 32" cylinders, a 200 psi boiler pressure, they exerted 82,982 pounds of tractive effort and each weighed 404,000 pounds. TheR-2s had better steaming qualities than the R-1s with a higher superheat ratio, much shorter firetubes, better factor of adhesion and a larger grate. They also had coned boilers, 16" piston valves, and outside radial valve gear.

The last group of "Santa Fes" was the twenty-five allocated by the USRA. The locomotives were also built by the American Locomotive Company and designated as Class R-3 and given road numbers 4200 through 4224. They had 63" diameter drivers, 30" x 32" cylinders, a 190 psi boiler pressure, they exerted 73,825 pounds of tractive effort and each weighed 384,225 pounds.

There are no surviving Erie 2-10-2 "Santa Fe" type locomotives.

Class Details by Steve Llanso

Class R-1 (Locobase 382)

Data from Erie 4 - 1928 Loco Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. See also DeGolyer, Vol 55, pp. 85+ and "Erie 2-10-2 Type Locomotive", Railway Age Gazette, Vol 58, No 13 (26 March 1915), pp. 706-707.

The data given are for engines that had as part of the firebox heating surface 126 sq ft (11.7 sq m) of thermic syphons and 20 sq ft (1.85 sq m) of arch tubes. Another variant had no thermic syphons and 37 sq ft (3.4 sq m) of arch tubes -- total firebox heating surface amounted to 358 sq ft (33.25 sq m) and total heating surface came to 5,684 sq ft (528.05 sq m). Its piston valves each measured an impressive 16" (406 mm) in diameter and received steam through passages that RAG reported were "unusually direct and of liberal section area."

Large, powerful freight engines. The first, Baldwin-built (#4000) was the prototype with a 90-in diameter boiler; see Locobase 14580.

Later engines (built by Baldwin, Alco, and Lima) had minimum diameters of 96.25 in (2,445 mm). Their rough riding qualities were problematical until revised counterbalancing smoothed the way. All of the Erie's 2-10-2s were renowned for their great power, whether as road engines or pushers.

Class R-1 (Locobase 14580)

Data from DeGolyer, Vol 55, pp. 71+. Works number was 41895 in February 1915.

See Locobase 382 for the production variant of this Santa Fe.

Class R-2 (Locobase 383)

Data from table in May 1916 issue of Railway Mechanical Engineer (RME), supplemented by the Erie 7-1949-1 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

30 R2s were built between 1915-1917. Said to have had better steaming qualities than the R1s, they had a higher superheat ratio, much shorter firetubes, better factor of adhesion (though not by much), and a larger grate. They had coned boilers, 16" (406 mm) piston valves, and outside radial valve gear.

Class R-3 (Locobase 384)

Data from Erie 4 - 1928 and 7-1949-1 Loco Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

25 USRA Heavy Santa Fe engines that proved the longest-lived of all Erie 2-10-2s, lasting until 1949-1952. A bit smaller than the earlier Erie 2-10-2s (down to the use of 14" piston valves rather than those of 16"), they were typical USRA designs in their balance and well-integrated components.

This entry shows the later configuration when the basic firebox had 28 sq ft of arch tubes and 106 sq ft of thermic syphons adding to the firebox heating surface.
