USA: The US Navy has taken delivery of a diesel-hydraulic locomotive which has been custom designed and built by Brookville Equipment Corp for shunting at the Puget Sound Naval Shipyard & Intermediate Maintenance Facility in Bremerton, Washington.

Brookville's Director of Sales Chris Rhoades said the locomotive's 'unique drive system is similar to diesel equipment that Brookville designs and produces for underground mining applications, but on a much larger scale.'

The 80 tonne BL05 is designed for a service speed of 16 km/h, and has a wide central cab for easy operation in either direction. It has a 500 hp EPA Tier 3 compliant Cummins engine, with four-speed transmission, torque convertor and planetary final drive.

There are sliding couplers powered by on-board electric motors for negotiating curves of less than 24·4 m radius. The 'unique' custom bogie design includes a heavy steel frame encasing the drive shafts, transfer cases, braking equipment and chevron suspension.
