The first five J's were numbered 600-604, carried 70-inch drivers, and offered 73,500 pounds of tractive effort (boiler pressure reached 275 psi). As a late-era design they sported some of the best technology of the times such as a feedwater heater (Worthington Type G5-A) for higher water temperatures and an automatic stoker (Standard Type HT). In addition the J's were equipped with more Timken roller bearings (greatly reducing wear on moving parts) than any other locomotive; they were added to all axles, main and side rods, valve gear, and wrist pins. Finally, there was the streamlining. Some railroads worked with manufacturers or hired industrial designers to provide the locomotive with an eye-catching look and invoke the appearance of speed, even while stationary.
However, again going its own way, the N&W kept this work in-house turning to its own Frank C. Noel of the railroad's passenger car department. He came up with a design that was somewhat similar to the Milwaukee Road's streamlined Atlantics and Hudsons in that the shrouding generally followed the natural lines of the locomotive. Overall, the J's carried a bullet-like appearance with skirting along the running-board which was painted Tuscan Red adorned in gold-leaf pinstriping and lettering. The rest of the locomotive was standard black. It was a rather simple, yet very elegant, look. The company wasted no time in featuring its new 4-8-4's in promotional material and advertisements (especially after the war), drawing wide acclaim and celebrity for the J's, which carries through to this day. While the J's have been revered for their good looks their mechanical might has made them just as legendary.
The J Class
Aside from their power the N&W went far beyond the major manufacturers, and various railroads' own custom-built designs, to produce a state-of-the-art locomotive. Mr. Dixon notes the J's were equipped with Nathan engine oil lubricators, which automatically lubricated 208 points on the locomotive as well as a valve lubricator to automatically grease valves, pistons, and other important components. There were also pressure grease fittings offering yet another means of lubrication for vital parts. Such details not only decreased wear but also increased their service periods, allowing the J's to go 15,000 miles, or about 18 months, between major overhauls.
The initial J's entered service between October of 1941 and January of 1942, assigned to the Cavalier and Pocahontas. They were joined by six others in 1943, listed as Class J-1 and numbered 605-610. The N&W was not allowed to build these variants to the same high standards (including streamlining and lighter components) because of wartime restrictions. As a result, they were largely used for freight service, a task at which they were also quite capable thanks to their smaller drivers and high tractive effort. In 1946 the N&W launched the first postwar streamliner when it debuted the all-coach Powhatan Arrow between Norfolk and Cincinnati. The J's were normal power this train. At this time the railroad also overhauled #605-610 with streamlining and upgrades to match #600-604.
With demand still high in the postwar years the N&W elected to build three more 4-8-4's, #611-613, which proved the most powerful of the fourteen offering 80,000 pounds of tractive effort and boiler pressures of 300 psi. At around the same time the railroad upgraded the other eleven to similar specifications. For the next eight years the J's continued handling N&W's top trains, and also powered a number of Southern's trains between Lynchburg, Virginia and Bristol, Virginia/Tennessee (including the Tennessean, Pelican, and Birmingham Special). Alas, their fall from grace was swift. When the N&W gave up on steam in 1958 they were quickly pulled from the roster while a few carried on in local freight service. All but one of the fourteen J's were retired and scrapped between October of 1958 and August of 1959.
Thankfully, #611 was saved and donated to the city of Roanoke where it was put on display at the Virginia Museum of Transportation. It found new life in 1981 after restoration saw the unit pulling excursions on Norfolk Southern's steam program for more than a decade. It was then retired again in 1994, making its last run on December 7th, following the end of the steam program. In 2011 NS brought back its program and whispering soon began regarding the possible restoration of #611. That dream came closer on February 22, 2013 when the Virginia Museum of Transportation announced it had created the Fire Up 611 Committee to launch a feasibility study looking at potentially operating the locomotive once more. The ultimate decision was a resounding "yes!" and #611 will soon be in full operation by the summer of 2015.
