SJ Tb

Tb is a diesel-electric locomotive used by Banverket of Sweden, for line service and snowploughing. Ten locomotives were built for Swedish State Railways (Statens Järnvägar, SJ) in 1969-1970 by Nydquist & Holm (NOHAB), for combined freight and snowploughing service, along with 20 smaller Tc locomotives. When Banverket was demerged in 1988, the Tb was transferred to it.
