1. The Class Ps-4-type steam locomotives of the Southern Railway were inspired by handsomely painted British locomotives. The Ps-4's green and gold livery set these locomotives apart from the funereal black associated with most American steam locomotives in the 20th century. The distinctive green was exclusive to locomotives on the Southern Railway that were assigned to the company's principal passenger trains, such as the Crescent Limited, the Piedmont Limited, and others.

The Charlotte Division was part of the Southern's Washington–Atlanta mainline, with extension of the mainline to Birmingham and New Orleans on track leased by Southern. The Charlotte Division included the line between Greenville, S.C., and Salisbury/Spencer, N.C. Thus the 1401 rarely, if ever, ran north of Spencer, home of the Southern's vast Spencer Shops for the heavy repair of locomotives from throughout the system.

A Ps-4 was capable of hauling 12–15 steel passenger cars, about 700–1000 tons, at 80 mph on level track. (The hill-and-dale profile of the Charlotte Division, however, kept average speeds to about 50–60 mph.) The 14,000 gallons of water in the tender permitted runs of about 150 miles—the full length of the Division—between water stops, although there would be one intermediate water stop normally scheduled. Fuel (16 tons of bituminous coal) in the tender was good for the full 150 miles.
