The prototype: The T 669 / Čmelák series

The T 669 series, later known as the 770 series, was developed in Czechoslovakia as a versatile diesel locomotive. Its nickname "Čmelák" (bumblebee) is derived from the Russian series designation ЧМЭ3 ("Tschme3") and its characteristic humming when starting up. With an output of 1,400 hp, the T 669 proved its worth in heavy shunting services as well as in light and medium freight transport.

The robust machines were produced in large numbers from the 1960s onwards and characterized the appearance of the CSD for many years. Their versatility and reliability made them an indispensable part of railroad operations in Czechoslovakia.
