 is the best-known, the design was actually quite new. Some steam experts have claimed the Niagara to be the ultimate locomotive, as it had the speed of an FEF (the Union Pacific's nickname for their 'four eight fours' was FEF) and the power of Northerns with smaller driver wheels.

Locomotive details

The first actual Niagara ordered by the NYC was Class S-1a #6000 in 1945. The S-1b (6001-6025) were delivered in 1945-46. These were built as mixed-purpose locomotives. The 4-8-4 traditionally is a passenger locomotive, which the NYC used its Niagaras for after World War II, but War Production Board

 regulations prohibited the building of passenger engines in 1945. The NYC's last steam locomotive was a Class S-2 Niagara: #5500; it had poppet valves. One notable trait of the Niagaras was that they did not have steam domes, as most other steam locomotives did, which resulted in a very smooth contour across the top of the boiler. A perforated pipe was used to collect steam instead. This was necessary because of the lower loading gauge of the New York Central (15 ft 2 in versus 16 in 2 in (4.93 m) for the other American railroads).

These locomotives had quite a small water capacity (18,000 US gallons 68,000 litres) in the tender, because the New York Central was one of the few in North America which used track pans (or water troughs). This allowed for a larger coal capacity, which enabled the New York to Chicago run to be done with only one intermediate fueling: usually at Wayneport, New York (a few miles east of Rochester). Fuel capacity was an enormous 92000 pounds (41.7 t).

On test, these locomotives achieved 6700 hp, and ran an average of 26,000 miles per month.

All bearings were either roller bearings or needle rollers.

Maintenance

The six days per week running schedule of these locomotives meant that all of the maintenance work normally done over the course of that week would have to be done on one day. This meant a specialized system was developed, where men in "hot suits" (asbestos heat-resistant coveralls) entered the firebox while the locomotive was still in steam and cleared all of the tubes, repaired the brick arch, etc. As the temperature inside the firebox itself would have been well over 100 degrees Celsius (212 F), and the working area these maintenance workers would have been standing on was the still-hot firebars of the grate, all references describe these workers as 'heroic' (reference: pages 172 ~ 173 The Great Book of Trains, Brian Hollingsworth and Arthur Cook (Bedford Editions, Salamander Books, 1987) )

This type of intensive maintenance was studied by steam locomotive designers such as Andre Chapelon

, and David Wardale. These designers based their modern steam locomotives on the experience gained in these Niagara-class locomotives: reliability; and a close attention to details leading to a reduction in maintenance costs.

The 1946 steam-versus-diesel trials

Six of these locomotives were chosen by their designer, Paul W. Kiefer, to participate in the famous 1946 Steam Versus Diesel road trials, where the 6000 hp Niagaras were put up against some 4000 hp diesels (E7's). The locomotives were run along the 928.1 miles (1,493.6 km) from New York (Harmon) to Chicago, via Albany, Syracuse, Rochester, Buffalo, Cleveland, Toledo and Elkhart, and return. The results were actually very close, as the table below shows:

The results were much closer than the diesel salesmen were comfortable with, but these steam locomotives were hampered by several factors: a series of coal miners' strikes; aggressive dieselization sales efforts; and a failure of the highly-expensive firebox-wrapper metallurgy to withstand the conditions of actual operation. (reference: pages 172 ~ 173 The Great Book of Trains, Brian Hollingsworth and Arthur Cook (Bedford Editions, Salamander Books, 1987) )

 ($77/t) (at the time of writing): a 1,555% increase since 1946.

The last days of the Niagaras

As the firebox wrappers failed, the locomotives were withdrawn, and eventually all were scrapped. According to the following, the retirement dates are below:

http://madisonrails.railfan.net/lewman31_niagaras_retired.html

May 1955 - Niagaras 6000-6025 (26 engines) still on roster. (5500 had been retired 1951).

August 1955: 19 Niagaras retired, leaving 6000, 6007, 6015, 6019, 6020, 6023, 6024.

November 1955: 6007 retired.

March 1956: 6000, 6019, 6020, 6023, 6024 retired, leaving only 6015.

June 30, 1956: Last run of 6015 in passenger service, Train No. 416, Indianapolis to Cincinnati on account of a diesel failure. Departed Indianapolis 34 minutes late, arrived Cincinnati 6 minutes late.

July 2, 1956, Returned to Indianapolis in freight service, train CC-3. Final run.

The dates of scrapping are unknown at this stage, but this was believed to have occurred at Granite City, Illinois (just east of St. Louis, Missouri).
