TORONTO - GO Transit is spending $125 million to purchase 50 bi-level railway coaches from Bombardier (TSX:BBD.B) for its inter-regional commuter service into Toronto.

The 162-passenger coaches will expand the system's capacity by 8,000 commuters per day.

Production of the coaches is scheduled to begin in June at Bombardier's facility in Thunder Bay, Ont., with deliveries beginning in the fall.

The Bombardier-designed double-decker coaches have been part of GO Transit's fleet since 1978.

GO Transit is the province's inter-regional public transit system linking Toronto with surrounding communities, including the Hamilton area.

Bombardier said the railway car is the most popular multi-level commuter rail car in North America, used in 13 major cities, including Montreal, Vancouver, Los Angeles and Dallas.

The order will include the 1,000th car manufactured in Thunder Bay.
