ST43 is the name for a Romanian diesel locomotive, produced by Electroputere, exported to and operating in Poland.

In the early 1960s a need appeared in Poland for urgent introduction of locos able to haul heavy freight.

This was caused mainly by the intensification of transport on south–north line, especially from the Silesian coal mines to Szczecin and Świnoujście harbours.

Lack of experience in building diesel locos for that purpose was the reason why the first ones had to be bought from Romania.

In March 1965 first 30 items of 060DA locomotives (factory number of ST43) were introduced into Poznań and Szczecin, according to agreement with Romanian producer.
