The Norfolk and Western J class was a class of 14 4-8-4 "Northern" streamlined steam locomotives built by the Norfolk and Western Railway (N&W) at its Roanoke Shops in Roanoke, Virginia, between 1941 and 1950. The most powerful 4-8-4 locomotives ever produced, the J class were part of the N&W's "Big Three" (along with the class A and Y6 freight locomotives) that represented the pinnacle of steam technology.

Contents

They were built to pull the Powhatan Arrow , the Pocahontas, and the Cavalier passenger trains on the N&W main line between Norfolk, Virginia, and Cincinnati, Ohio; they also ferried the Southern Railway's Birmingham Special , Pelican , and Tennessean between Monroe and Bristol, Virginia, until these trains were taken over by diesel locomotives in the summer of 1958.

The class J locomotives were subsequently reassigned to haul local freight trains; all save one were retired and scrapped by the end of October 1959.

The lone exception was No. 611, which was donated to the Virginia Museum of Transportation (VMT) in 1962. It has been restored twice: once as part of the Norfolk Southern Railway's steam program in 1982, and again as part of the VMT's Fire up 611! campaign in 2015.

History

Background

A drawing design of the N&W class J locomotive

In the late 1930s, the Norfolk and Western Railway's (N&W) K2 and K2a 4-8-2 "Mountains" could not handle the rising passenger traffic after the Great Depression abated, so the N&W sought a more powerful and fancy-looking passenger steam locomotive. [3] [4] The N&W mechanical department team originally considered a class N 4-8-4 type, but deemed its 63 in (1,600 mm) driving wheels inadequate for the N&W's railway grades. [3] [5] N&W mechanical engineer H.W. Reynolds redesigned the drivers' diameter to a 70 in (1,778 mm) design that could be counterbalanced against wheel slippage. [3] [6] In 1940, N&W passenger car supervisor Franklin C. Noel originally drew a design, which was based on the Southern Pacific GS class, but the N&W officials rejected it as "too plain". [7] [8] Noel reproposed the design with an almost similar specification to the streamlined New York Central Hudson, but was rejected again for being "too fancy". [7] [8] On the third and final concept, Noel developed the class J bullet-nosed design to give the locomotive smoothness and beauty along with speed, power, and dependability. [3] [7] His wife Louise suggested painting the locomotive black with a Tuscan red stripe wrapped with golden yellow linings and letterings. [3] [9] The N&W officials were satisfied with the final design and considered it to be the most beautiful streamlined steam locomotive ever. [7]

Design

In the summer of 1941, the first of the J class, No. 600 was constructed at the N&W's Roanoke (East End) Shops in Roanoke, Virginia, and completed on October 20. [10] It sported a streamlined pilot with a retractable coupler that could horizontally swing out, a bullet-shaped nose with an enclosed headlight mounted into the nose, and a skyline casing that encased the smokestack, sand dome, steam dome, bell, whistle, and safety valves on top of the boiler. [9] Among the running boards, there was a broad skirting mounted from the cab and firebox sides forward over the cylinders, then narrowing as turned into the pilot. [9] The class J tender is a 22D-type, which holds 26 short tons (52,000 lb) of coal and 22,000 US gallons (83,000 L) of water. [11] No. 600 was equipped with Timken roller bearings and lightweight reciprocating parts on it axles, rods, pistons, crossheads, valve gear, and wrist pins, which provided the locomotive a smooth run and quicker acceleration. [9]

The Roanoke Shops built four more locomotives; No. 601 on November 17; No. 602 on December 8; No. 603 on December 24; and No. 604 on January 27, 1942. [12] [13] No. 602 was equipped with a trailing truck booster, which increased starting tractive effort from 73,300 lbf (326.05 kN) up to 85,800 lbf (381.66 kN). [13] In December 1945, No. 602's booster was removed for easier maintenance; that same summer, the class had its boiler pressure raised from the original 275 psi (1.90 MPa) to 300 psi (2.07 MPa). [14] The result was an increase in the starting tractive effort of the main engine to 80,000 lbf (355.86 kN) (rendering the booster on No. 602 superfluous), and an increase in maximum drawbar horsepower from 4,700 hp (3,500 kW) to 5,100 hp (3,800 kW) at 41 mph (66 km/h).

The driving wheels were small for a locomotive that was able to pull trains at more than 100 mph (160 km/h). [1] To overcome the limitation, the wheelbase was made extremely rigid, lightweight rods were used, and the counterbalancing was precise – so precise that it could theoretically allow the locomotives to reach speeds up to 140 mph (230 km/h) without the rail damage that could have occurred with conventional designs. [1] One drawback of this highly engineered powertrain was sensitivity to substandard track. [1]

While on loan in 1945, No. 610 hauled a 1,015-ton passenger train with 11 to 15 cars at speeds of more than 110 mph (180 km/h) over a section of flat, straight track known as the "racetrack" in the Pennsylvania Railroad's Fort Wayne Division. [16]

The class J locomotives were built with automatic lubricators at 220 points, allowing them to operate up to 1,300 miles (2,100 km) between refills. [1] Despite their comparatively small driving wheels, they rode very smoothly at all speeds: the Pennsylvania Railroad's inspector stated that it rode better than any of their own steam locomotives except for the 6-4-4-6 class S1. They also steam very well due to the large grate. [16]

The first five locomotives (Nos. 600–604) were outshopped between October 1941 and January 1942, costing the railroad $167,000 apiece. [3] The second batch of six locomotives (Nos. 605–610) was delivered in 1943 at a cost of $168,550 each without streamlined casings and lightweight side rods, due to the limitations on the use of certain materials during the war; classifying them as the J1s. [17] [18] In 1944, the N&W were allowed to reclassified the J1s as Js with the lightweight rods and streamlined shrouding added. The last batch of three locomotives (Nos. 611–613), rolled out in summer 1950, were marked as the last steam passenger locomotives built in the United States. [19] In the mid-1950s, N&W engineers replaced the duplex (two) coupling rods between the main (second) and third drivers (tandem rods) on Nos. 600, 604, 607, and 611 with a single coupling rod. [20] Additionally, all of the J class locomotives' streamlined front end, underneath the bullet nose, was given access holes to give ventilation for the cross-compound air pumps from behind. [21]

Revenue service

The class J locomotives pulled the N&W's prominent passenger trains, such as the Powhatan Arrow, the Pocahontas, and the Cavalier between Norfolk and Cincinnati, as well as ferrying Southern Railway's (SOU) the Birmingham Special, the Pelican, and the Tennessean between Lynchburg and Bristol, Virginia. [1] [25] Because of their power and speed, the class Js were among the most reliable and efficient engines, running as many as 15,000 miles (24,000 km) per month, even on the mountainous and relatively short route of the N&W. [1] They also hauled additional mail trains and local passenger trains. [25] [26] Additionally, while pulling N&W's mainline passenger trains each month, the class J locomotives would take in turns to swap each other out in Roanoke and go to the Shaffers Crossing engine terminal for maintenance service and a washdown. [27] [28]

In 1941, No. 600 was put on public display: at Bristol on October 25; Winston-Salem, North Carolina, on October 27; Lynchburg on October 28, and Durham, North Carolina, on October 29. [29] [30] No. 600 made its first revenue runs in early November, pulling the Tennessean and Birmingham Special passenger trains as well as the Cavalier and Pocahontas trains. [31] [32] No. 603 entered service on December 26, 1941; it pulled local passenger trains between Roanoke and Bristol as a test before being assigned to haul the Pocahontas and Cavalier express passenger trains. [13]

In the summer of 1958, N&W's new president Stuart T. Saunders began to dieselize the railroad, ordering 268 GP9 locomotives from Electro-Motive Diesel (EMD). [33] However, Saunders did not receive the passenger GP9s and instead leased an E6A and four E7 units from the Atlantic Coast Line along with four E8 units Richmond, Fredericksburg and Potomac Railroad to replace the class J steam locomotives in passenger service. [33] [34] The class Js were reassigned to local freight service on the Norfolk Division, running between Norfolk and Crewe, Virginia. [35] In early 1958, their tenders' rear decks were outfitted with a cupola to accommodate the head-end brakeman. [36] [37] When the ACL E units returned to their railroad to handle heavy winter traffic in Florida, some of the class J locomotives briefly returned to passenger service until being replaced by N&W's new passenger GP9s, which arrived in late 1958. [33] Some of them continued to haul freight trains until their five-year boiler flue ticket certificate expired. [35] [36]

Accidents and incidents

Preservation

Only one locomotive, No. 611, has been preserved. [24] Its survival was in part due to its excellent condition after its 1956 derailment and subsequent repair, and also in part to the efforts of attorney and railfan W. Graham Claytor Jr., who offered to salvage the locomotive from the scrap line. [43] The No. 611 locomotive was donated to the Virginia Museum of Transportation (VMT) in 1963, where it sat on static display for two decades. [24] [43] Since then, it has had two excursion careers: from 1982 to 1994, after Norfolk Southern Railway restored the locomotive, and from 2015 onwards with the VMT. [24]

A 2-8-8-2, in the Whyte notation for describing steam locomotive wheel arrangements, is an articulated locomotive with a two-wheel leading truck, two sets of eight driving wheels, and a two-wheel trailing truck. The equivalent UIC classification is, refined to Mallet locomotives, (1'D)D1'. These locomotives usually employ the Mallet principles of articulation—with the rear engine rigidly attached to the boiler and the front engine free to rotate—and compounding. The 2-8-8-2 was a design largely limited to American locomotive builders. The last 2-8-8-2 was retired in 1962 from the N&W's roster, two years past the ending of steam though steam was still used on steel mill lines and other railroads until 1983.

Built as a fast freight locomotive, No. 759 served the Nickel Plate until being retired in 1959 and placed into storage. In 1965, No. 759 was purchased by F. Nelson Blount for display in his Steamtown, U.S.A. collection in North Walpole, New Hampshire. The locomotive was restored to operating condition in 1967 by New York commodity broker Ross Rowland for use in hauling his Golden Spike Centennial Limited, a special commemorative train that celebrated the 100th anniversary of the completion of the Transcontinental Railroad in 1969. Afterwards, No. 759 pulled numerous excursions for Ross Rowland and Steamtown until being retired once more and placed back on display in 1977. As of 2023, the locomotive remains on static display at the Steamtown National Historic Site in Scranton, Pennsylvania, and sibling engine No. 765 continues to operate in mainline excursion service.

The 21st Century Steam program was conducted by the Norfolk Southern Railway from 2011 to 2015, featuring four classic steam locomotives pulling passenger excursions along Norfolk Southern rails in the eastern United States.
