TURKEY: The city of Ankara has selected a consortium of Ansaldo Segnalamento Ferroviario and Alsim Alarko Sanayi Tesisleri Ve Ticaret as preferred bidder for a €175m contract to design, supply and commission signalling for metro lines M1, M2, M3 and M4 and to undertake electromechanical works on lines M1 and M3.

Ansaldo STS values its share of the contract at €107m. This includes the provision of radio-based communications-based train control, with lineside and on-board signalling, interlockings and centralised traffic control.

The 14·6 km long Line M1 between Kizilay and Batikent, serving 12 stations, was built by a consortium of Bombardier and SNC-Lavalin and opened in autumn 1997. Three further routes are currently under construction. Line M2 runs for 18 km south-west from Kizilay to Çayyolu along Eskisehir Road, and will have 16 stations. M3 will also be 18 km long, running west from Batikent to Sinkan and serving 11 stations. Line M4 is a 7·9 km branch with six stations heading north from Ulus to Keçiören. A 4·8 km extension south from TBMM on Line M2 to Dikmen is also planned.
