A facility for moving oil by railcars near Unity, Sask. is undergoing an expansion to boost the amount of crude it can ship.

TORQ Transloading Inc. said Tuesday that construction has begun on the expansion to its North West Terminal at Unity, in the west-central part of the province.

The company says the expansion means more storage and additional tracks, allowing for the handling of trains that have up to 120 cars.

Currently, the facility, which gets oil brought in by truck and then transfers it to rail, can accommodate 40-car trains.

The expansion is expected to be complete this fall.

The announcement follows news last week of a $100-million oil-by-rail hub that's planned for the Kerrobert area, about 60 kilometres south of Unity.

At the Kerrobert facility, oil will be shipped to the rail hub by trucks hauling crude oil from surrounding oil fields, and from a pipeline as well.
