| IRAN National railway RAI has completed a €31m project to increase capacity on its 926 km main line between Tehran and Mashhad, with the commissioning of the second phase of its resignalling programme.
In conjunction with the double-tracking of the line, new interlockings were installed at all stations. Of these, 12 electronic interlockings were supplied by Thales and 13 by local company Maharan; the remaining 25 stations were equipped with new relay interlockings supplied by Ircon with assistance from Siemens India.
To support the multi-block capacity increase, RAI has now installed 189 intermediate signals and associated ATP equipment, supported by new optic fibre and medium-voltage cabling along the entire route.
According to Maziar Yazdani, Director-General of Communications & Signalling at RAI, completion of the sectioning project will increase capacity on the Tehran - Mashad route three-fold, permitting the operation of up to 200 trains each way per day. This is expected to provide a significant boost for international transit traffic as well as domestic passenger and freight services.
Noting that the capacity increase ‘has been designed and operated by the skilful hands of Iranian experts for the first time, based on the latest world standards’, Yazdani said the development by RAI and its local partners had delivered the project at around half the cost of comparable schemes in other countries.
