Abstract
A locomotive suited for use as a switcher for road and/or yard work is provided. The switcher comprises a mother unit having an engine for converting fuel into electricity. The mother unit includes two trucks supporting wheels on a plurality of axles, and a plurality of traction motors to provide tractive force to the mother unit's axles. The switcher also includes a slug unit operatively coupled to the mother unit in a manner to transmit electric power, signals and hauling force. The slug unit can include at least one truck, which can be removed from a retired locomotive and at least one traction motor electrically coupled to the mother unit and operatively coupled to the axle(s). Sufficient ballast can be added to equalize weight per axle. The switcher combines the power of a locomotive with more axles with the maneuverability of a locomotive with fewer axles.
