Tacoma Rail is a publicly owned Class III shortline railroad. It is owned by the city of Tacoma, Washington and operated as a public utility. It is one of three operating divisions of the municipally-owned Tacoma Public Utilities service, but unlike other city services, the railroad is self-supported and generates revenue for the City of Tacoma and Washington state. Tacoma Rail provides freight switching services, serving the Port of Tacoma and customers in Tacoma, south Pierce County and parts of Thurston County. It operates 16 diesel locomotives, more than 100 employees and about 140 miles (230 km) of track, many of which are former Milwaukee Road and BNSF Railway lines around Western Washington.
