The Class T 448.0 (factory designation 1435 Bó Bó 883) is a group of four-axle diesel-electric locomotives manufactured by ČKD Praha for shunting and freight service on secondary and industrial lines built for industrial use in Czechoslovakia and Poland and for the Czechoslovak State Railways (ČSD). Following the dissolution of Czechoslovakia in 1993, these were divided between the successor companies, the Czech Railways and the Slovak Republic Railways. They have also found their way to a considerable number of private railways in both countries, and ten have been sold to the Korean State Railway of North Korea. Small numbers have also gone elsewhere, such as Italy and Serbia.
