TCDD E52500
Encyclopedia
TCDD E52500 is a series of electric locomotive
s used by the Turkish State Railways
, comprising 22 class 441-9
locomotives leased from Željeznice Federacije Bosne i Hercegovine
in Bosnia-Herzegovina. They are used throughout the electrified parts of the Turkish rail network. The locomotives have a power output of 3,860 kW and are capable of 120 km/h.
The locomotives were originally built from 1967 onwards for Yugoslav Railways by ASEA
of Sweden
and Končar
in Croatia
, then part of Yugoslavia. They were based on ASEA's Rb
design for Swedish Railways.
The first fifteen locomotives were delivered to TCDD in 1998, followed by five more in 1999 and two in 2004 and 2005 respectively. They have been modernised by having the diode
s replaced with thyristor rectifier
s, making them similar to the Rc, the thyristor-based successor to the Rb.
Two units were scrapped after the Tasvancil accident in 2004. The two replacement units delivered in 2004-05 have higher top speeds that the other units, who could only run at 140 km/h.
