Locomotive, Diesel, ČSD Class 750, 753, 754

History: The ČSD class 753 (nicknamed Brejlovec or Diving Googles) is a 1985 hp (1460kW) four-axle BóBó diesel-electric locomotive, initially designated as class T 478.3, built by ČKD Prague workshops for the Czechoslovak State Railways ČSD, between 1968 and 1977. A total of 408 units were built; it became one of the largest class of locomotives built in the country.
More than 150 locomotives of class 753 have been modified in the 1990s to class 750 by the introduction of an electric heating alternator; the output power was increased from 1325 kW to 1460kW, with equal traction power. Several dozens of these upgraded locomotives are still in operation in freight transport at ČD Cargo and other operators.
The ČSD class 754, initially designated as class T 478.4, is an improved version of class T 478.3, designed especially for passenger and express transport. A total of 86 units were built between 1975 and 1980. The first two prototypes produced in 1975 were later re-labeled 750 series (Inv. 409 and 410), and in 2011-12 they were rebuilt to 750.7 (today's 750,711 and 712).

Railroad/Company: ČKD (Českomoravská Kolben-Daněk) ) was one of the largest engineering companies in the former Czechoslovakia and today's Czech Republic.
It produced motorcycles, military vehicles, locomotives and tramways.
After WWII, ČKD was nationalized and became one of the world's leading producers of trams. These were produced by its subsidiary company, ČKD Tatra, that also manufactured metro cars and diesel locomotives.
In 1994 the company was privatized by the Czech government and transformed into a holding company that filed for bankruptcy in 1998. The transport company, ČKD Dopravní systémy (CKD Transportation Systems, known until 1997 as ČKD Tatra or simply Tatra) was sold to Siemens Mobility's Czech subsidiary, Společnost kolejových vozidel (SKV).
