* Linings require a minimum of SSPC-SP 10, Near-White Blast Cleaning for a hopper car
, and SSPC-SP 5, White Metal Blast Cleaning for a tank car.
For example, given that average total hopper car
cycle time is sixty days (see Table 1), a 23 percent reduction in Stage 3 car inventory, as demonstrated in Table 7 with a two-day reduction in Stage 2 standard deviation, would reduce overall car requirements by 8 percent.
In the example, changing the hopper car
unloading procedure is a work process change.
* Hopper car
coatings vary based on the type of cargo and climate (tank car coatings also vary based on the type of cargo).
Wilkey contacted a representative from Martin Engineering, who recommended the company's rugged, air-powered Railcar Openers, which can open even the most stubborn hopper car
