Version 4 Car
Introduced in 1999 by National Steel Car, this car is seen in large numbers across Canada and the United States. It was developed specifically to address the need for additional rail transport capacity caused be the growing Potash market.
Previously, the majority of Canadian Potash rail transport was accomplished with the larger Hawker Siddeley 4550 cu ft Cylindrical Hoppers and similar cars from National Steel Car and Marine Industries.
Though the car is a newer design, it has less capacity than the Hawker Siddeley style cars. However it makes up for this in a shorter car length of only 47 feet versus the Hawker Siddeley style cars at 59 feet. This allows a train of these cars to carry more Potash then a train of comparable length made up of the Hawker Siddeley style hoppers.
These cars operate at a gross rail load of 286,000 pounds, the current maximum limit. However, they are actually designed for a gross rail load of 315,000 pounds. They are currently produced with 100 ton nominal capacity trucks to suit present 286,000 lb. gross rail loading. If the maximum weight limit is increased, these cars can be upgraded with 125 ton trucks allowing for maximum cargo capacity going forward.
These cars are currently operated in large numbers by both Canpotex and the Potash Corporation of Saskatchewan, and in smaller numbers by other operators, and now Nutrien. To date, over 10,000 have been produced in six versions. These cars are seen on a daily basis traveling across the Canadian Pacific, Canadian National, BNSF, CSX, NS and Union Pacific rail networks.
National Steel Car produced Version 4 of the car with internal modifications to the car design to increase capacity to 4300 cu. ft. These modifications are not visible from the outside of the car. These cars also introduced a redesigned flat sided chute design and revised A End configuration.
The first production run for PotashCorp, which was the fifth production run of these cars was of 1000 cars.
