Tp was a diesel-hydraulic locomotive operated by Statens Järnvägar for hauling freight trains on its narrow gauge (891 mm/2 ft 11 3⁄32 in) railways. 25 were built in total 20 by Maschinenbau Kiel and five on licence by Svenska Järnvägsverkstäderna (The Swedish Railway Workshops).During the 1960s most of the narrow gauge railways were converted to standard gauge and SJ chose to rebuild the locomotives to this gauge and also change the axle system to D giving them the designation T23.
