Locomotive modernization

This is reported by the railway magazine Railway Supply.

The agreement provides for an option to upgrade five more units. Previously, the parties agreed to modernize 50 of these locomotives at a cost of less than CZK 42 million (€1.7 million) each.

Class 742 diesel locomotives were produced between 1977 and 1986, and CD Cargo is now trying to find parts to service 140 units.

During the modernization, the frame and chassis of the locomotive are modified, and the remaining components are replaced with new ones with the installation of ETCS signaling system equipment.

Frame and running gear work will be carried out in Česká Trebova, while kit production and assembly will take place in Jihlava.

Diesel locomotive 742.71X has a speed of up to 100 km/h with a power of 1 MW. Currently, CD Cargo has 37 such vehicles, which are approved for operation in the Czech Republic and Slovakia.
