Private Car Allocation System (PCAS)
Developed by Union Pacific to create a more equitable and transparent covered hopper allocation process to provide improved shipment forecasting, fleet efficiency, and service. Commodities transported in PCAS are limited to soybean meal and hulls (STCC 20923). The covered hoppers distributed in PCAS are from two (2) Union Pacific controlled system pools, the guaranteed pool and the general distribution pool. Shippers will maintain their existing privately owned cars and continue to utilize them on Union Pacific for loading and transportation of the specified commodities.
