The SMM (Sistema Metropolitano de Mobilidade - Metropolitan Mobility System) will serve Coimbra, Miranda do Corvo, and Lousã, with electric buses ('metrobus') on a dedicated track, featuring suburban operation (between the three municipalities) and urban operation in the city of Coimbra, with connections to the Coimbra-B train station and the University Hospitals of Coimbra, which are expected to be operational by 2026.

After several delays, the 'metrobus' system is now operating on the suburban section between Portagem (Coimbra) and Serpins, a 36-kilometer route with 27 stations, representing the completion of the first phase of the project.

The service to Serpins will operate on the schedule planned for the normal SMM operation (between 5:30 AM and approximately 1:00 AM), after having operated in the preliminary phase in Coimbra with a shorter schedule (from 7:30 AM to 8:00 PM) and less service.

The start of operations for the 'metrobus' comes after three decades of numerous alterations, suspensions, and postponements to this mobility project.

The Ministry of Infrastructure and Housing, which manages the project, estimates that the SMM (Metro Mondego Metropolitan System) will be used by 13 million people per year, following an investment of €220 million, supported by the State Budget and EU funds.

When the urban section is fully operational, the 'metrobus' will have a total length of 42 kilometres and an equal number of stations.

In the urban area, during peak hours, the electric buses will run at five-minute intervals in each direction.

Metro Mondego, the concessionaire for the operation of the SMM, stated today that the start of service between Coimbra and Serpins "will transform mobility in the Coimbra region."

According to the partnership formed by the State and the municipalities of Coimbra, Lousã and Miranda do Corvo, the first 'metrobus' will depart from Serpins, in the municipality of Lousã, at 05:30, heading to Portagem station, in the heart of downtown Coimbra.
