TCDD E52500 is a series of electric locomotives used by the Turkish State Railways, comprising 22 class 441-9 locomotives leased from Željeznice Federacije Bosne i Hercegovine in Bosnia-Herzegovina.

The locomotives have a power output of 3,860 kW and are capable of 120, 140 or 160 km/h speed depending on the version.

The locomotives were originally built from 1967 onwards[1] for Yugoslav Railways by ASEA of Sweden and Končar in Croatia, then part of Yugoslavia.

They have been modernised by having the diodes replaced with thyristor rectifiers, making them similar to the Rc, the thyristor-based successor to the Rb.

These locomotives were withdrawn from TCDD on April 3, 2011 upon finish of the lease contract.
