Metroselskabet Launches EUR 1.35B Copenhagen M5 Tender

COPENHAGEN, Denmark – Metroselskabet initiated procurement for the first phase of the M5 metro line in 2026, issuing two separate tenders worth a combined EUR 1.35 billion. The civil works tender is valued at EUR 800 million and the transportation systems contract at EUR 550 million, with contract awards scheduled between September 16 and December 27, 2026.

What Does This Contract Cover?

The M5 Phase 1 transportation systems contract encompasses design, supply, and integration of rolling stock, GoA4 CBTC signalling, railway infrastructure, and a control and maintenance centre (CMC). The civil works tender covers construction of six stations—five underground and one above ground—along with 7 km of bored tunnels and a 2-km viaduct. The transportation systems package includes an initial order of 14 automated trains and long-term maintenance services, with contractual options for up to 5 additional trains, an extension from Prags Boulevard to Refshaleøen, and a further extension from Refshaleøen to Lynetteholm.

Key Contract Data

How Does This Compare to Similar Contracts?

The EUR 1.35 billion M5 Phase 1 investment sits within a broader European trend of metro expansion tied to urban development. By comparison, Poland’s Budimex secured a €34 million contract in 2023 for preparatory drilling of a 4-km high-speed rail tunnel in Łódź, part of the Warsaw–Łódź “Y” line where 19 firms are currently bidding across six procurement procedures for the broader corridor (Source: GlobalConstructionReview, 2023). The Copenhagen M5’s scale—combining civil works and transportation systems in an integrated tender approach—differs from Poland’s segmented procurement model. Meanwhile, the Denmark railway signalling market is projected to grow alongside FRMCS adoption and digital signalling investments, aligning with the M5’s GoA4 CBTC specification (Source: IndexBox, 2025). Metroselskabet’s three-year industry dialogue prior to tender launch mirrors practices seen in major European infrastructure programmes, where early contractor engagement shapes technical requirements and risk allocation.

Editor’s Analysis

Metroselskabet’s decision to bundle rolling stock, signalling, and long-term maintenance into a single transportation systems contract signals a shift toward lifecycle procurement in urban metro projects. The inclusion of three expansion options within the base contract gives the winning bidder a pathway to additional work through 2045 while allowing the authority to avoid re-procurement delays. The “pain/gain” mechanism and geotechnical baseline risk-sharing model indicate that Danish authorities are absorbing lessons from cost overruns on earlier European metro projects. Passenger data supports the investment case: the network carried 135 million passengers in 2025, an 8% year-on-year increase, and the M4 southern extension exceeded initial traffic estimates by 50% following its June 2024 opening.

FAQ

Q: When will the Copenhagen M5 metro line open?
A: The first section of the M5 line, covering the southern segment between Copenhagen Central Station and Prags Boulevard, is scheduled to become operational in 2036. The northern segment toward Lynetteholm is planned to enter service in 2045.

Q: How many trains will the M5 line use?
A: Phase 1 includes delivery of 14 automated metro trains, with a contractual option for up to 5 additional trains. The exact manufacturer has not been selected; bids are being solicited through the transportation systems tender.

Q: What is the total cost of the Copenhagen M5 project?
A: Phase 1 is estimated at EUR 1.35 billion, split between civil works (EUR 800 million) and transportation systems (EUR 550 million). The total cost for the full M5 line, including the northern segment and possible circular extension, has not been disclosed by Metroselskabet.
