The TCDD E32000 is an electric multiple unit railway car built by Hyundai-Rotem for the Turkish State Railways. They were ordered exclusively to operate along the Marmaray commuter rail network in Istanbul with delivery beginning in 2011. The EMUs consist of 5-car and 10-car sets respectively. The first EMUs went into service along Istanbul's two commuter rail lines from 2012 and 2013. On 29 October 2013, the first 5-car sets began operating between Kazlıçeşme and Ayrılıkçeşmesi as part of Phase I of the Marmaray project.

Hyundai Rotem announced on 11 November 2008, that it had signed a €580 million contract to supply the rolling stock for the Marmaray project. The Korean firm had competition from shortlisted bidders Alstom, CAF, and a consortium of Bombardier, Siemens, and Nurol for the 440-vehicle contract which was placed by the Ministry of Transport's General Directorate of Railways, Harbours, and Airports.
