History

The locomotive was developed from the ČSD Class T 448.0 shunting locomotive, modified to be more suited to ČSD's needs, including a higher top speed, lower axle loads, and the relevant signalling equipment.

The first series of 60 locomotives started to be delivered in 1977, and were allocated to depots at Bratislava, Leopoldov, Bohumín, Děčín, Trutnov, Plzeň, Ostrava, Hradec Králové, Liberec, and Ústí nad Labem. In total 494 locomotives were built, of which 438 went to the Czechoslovak State Railways

One of the locomotives, T466.2037, was the 1000th locomotive produced by ČKD Praha.
