PRAGUE Public Transit (DPP) has issued a call for tender to prequalify companies for a turnkey contact worth around Koruna 86bn ($US 3.66bn) to supply rolling stock and automate Prague metro lines C and D.

Under the contract, the chosen contractor will supply 69 five-car metro trains with maintenance for 35 years, install automatic train operation (ATO) using a CBTC system to achieve grade of automation 4 (GoA4) on lines C and D, and install platform screen doors and maintain them for 25 years. The contract will also include the modernisation of two depots.

DPP will confirm the number of trains during the consultation phase with bidders. DPP wants to operate trains on the 22.4km Line C at headways of at least 90-seconds and achieve a 20% increase in capacity.

Construction of the first 10.6km section with 10 stations of Line D is currently underway. DPP plans to procure 10 trains initially for the line, rising to 16 sets. This figure will also be confirmed during the consultation.

Trains for Line D will be delivered first, followed by the 53 sets earmarked for Line C. All axles will be motored to cope with 4% gradients.
