The E 424.001 and E 424.002 were electric shunting locomotives of the Czechoslovak State Railways (ČSD). They were used on the previous 1.5 kV direct current system in the Prague railway junction .
history
At the beginning of the 1920s, the ČSD planned a comprehensive electrification of their railway lines with 1500 volts direct current. In 1925, ČSD ordered a total of 16 electric locomotives for the first planned routes in the Prague hub. These included two locomotives for shunting and light freight train service, which were to be built by Škoda in Plzeň . Škoda delivered the two locomotives in 1928 at a unit price of CZK 1,590,000. to the ČSD.
The E 424.001 was also used outside the Prague junction in the 1950s, for example in freight traffic on the Rybník – Lipno nad Vltavou railway line . When the catenary voltage in the Prague node was raised to 3000 volts on May 16, 1962, both came to the Tábor – Bechyně railway in South Bohemia in 1963 , where they were only used briefly. The 424.002 was taken out of service there in 1963 and scrapped in 1967. The 424.001 remained in operation until 1964 when it was parked in the Plzeň depot. In 1977, on the occasion of the 50th anniversary of the construction of electric locomotives at Škoda, it was installed on the factory premises in Pilsen as a monument locomotive. By mistake, she was given the number of her sister locomotive 424.002.
It has been exhibited in the Techmania Science Center in Pilsen since 2010 .
technical features
The locomotives had a split frame that was connected with a close coupling. The driver's cab was located in the middle of one of the two frame halves, and the electrical equipment with the traction motors was arranged under the front end. The traction motors were designed as double motors, which transmitted their power to the axles fixed in the frame via a back gear and coupling rods.
