Italy-based Ansaldo has been marked as the preferred bidder for the contract to build Cityringen, Copenhagen's new metro system in Denmark.
The company has proposed to offer technical services worth around €700m ($932.6m), but the precise scope of the contract and related price will be finalised during the negotiations.
If finalised, Ansaldo will build a 16km city circle line for an automated, driverless metro in Copenhagen, which will include 17 underground stations.
Ansaldo said it will plan and construct power systems, communications systems, platform-edge doors, signalling, carriages, as well as providing five years of operation and maintenance, with an option for a further three years.
The trains will be supplied by Ansaldo Breda, and the metro system is expected to be operational by 2018.
