Hydraulic Switchers 10-22

DTC-2 (Diesel Torque Converter) 500 hp (twin Caterpillar) 44-ton.

These were a Canadian-only locomotive designed without main generators and traction motors to eliminate the need for an electrician at small shops, requiring only a diesel mechanic. The units were assigned to small yards across the system.
Their weight was under 90,000 pounds thus permitting operation without a fireman another advantage in small yards. .

Note: These units were always referred to as "HS-xx" for Hydraulic Switcher
