#1401, a Pacific type (4-6-2) locomotive, was built for the Southern Railroad at Alco's Richmond, VA, works in 1926. Sixty-four of these Ps-4 Class were built, the first twenty-seven by Alco between 1923 and 1924 (#1366-#1392).
Derived from the USRA "heavy" Pacific type, but with smaller drivers (73" instead of 79"), the first twenty were amongst the largest locomotives built for the Southern, only slightly smaller than its Ts-1 Class Mountain (4-8-2) types. The engine weighed 300,000 lbs, 180,000 lbs on its drivers. With 27" x 28" cylinders, a 70.4 sq ft grate, 314 sq ft firebox, 4,578 sq ft heating surface (including 860 sq ft superheating) it operated at a boiler pressure of 200 psi, delivering 47,535 lbs tractive effort. The tender weighed 195,600 lbs light with a capacity of 16 tons of coal and 12,000 gallons of water.
#1401 was one of the second batch of thirty-seven Ps-4s delivered in 1926 (#1393-#1409, #6476-#6482 and #6688-
#6691), thirty-two from Alco and five from Baldwin. At 304,000 lbs, they were slightly heavier than the first batch and, with a 7.5 sq ft grate and total heating surface of 4,594 sq ft, including 905 sq ft superheating, had slightly more heating surface, although this made no appreciable difference to the 47,535 lbs tractive effort. They were also mated with larger tenders weighing 261,600 lbs with a capacity of 16 tons of coal and 14,000 gallons of water.
A Ps-4 could haul 12-15 steel passenger cars, about 700-1,000 tons, at 80 mph on level track,
but the rolling profile of the Charlotte Division kept #1401's average speed down to about 50-60 mph.
#1401 is perhaps best known for joining one of eight double-headed
Ps-4s (with #1385 from Greenville to Spencer, NC) that pulled President Franklin D. Roosevelt's funeral train from Warm Springs, GA, to Washington, DC, in April 1945. #1401 was fully shopped in 1951, retired in 1952 and donated to the Smithsonian in 1953.
Taken to the Henry Street Yard in Alexandria, VA, it was cosmetically restored at Shelton Paint Shop in 1961. Southern paid for and supervised the restoration, as well as for transporting #1401 to the museum in November that year.
Above, #1401, mounted on a flatbed trailer waiting to move into National Museum of History & Technology. Note that the pilot has been removed. The tender is nowhere in evidence and must have been transported separately. #1401 was officially dedicated in June 1962, and went on display in 1964.
