These locomotives were intended for goods traffic and Sunday excursion services on the lines of the Berlin Stadtbahn.

Later the T 14 was also procured by other railway divisions for goods trains on main lines and even for passenger services.

After the Second World War the Deutsche Reichsbahn (GDR) incorporated further T 14s, which came from France and Belgium, as 93 451 to 93 459.

In the East German Deutsche Reichsbahn the last ones were even given new computerised numbers in 1970 and classified as DR Class 93.8.

Another unit, PKP TKt1-63, is preserved in Poland at Chabówka railroad museum.
