Comboios de Portugal (CP) has ordered 117 new electric multiple unit (EMU) trains from an Alstom/DST consortium, marking the largest acquisition of rolling stock in its history.
This order includes 62 units intended for urban or commuter services and 55 units for regional services. The agreement also includes the provision of spare parts, special tools, and the construction of a rolling stock maintenance depot in Guifões, Matosinhos.
The total investment amounts to 746 million EUR, with 117.6 million EUR expected to be co-financed by European funds and 212.5 million EUR to be secured from the Environmental Fund. Delivery of the first trains is scheduled to begin in 2029. The contract will proceed through standard procedures and will be submitted to the Court of Auditors for review.
This acquisition is intended to renew and modernise part of CP’s existing fleet and to enhance capacity. The new trains are expected to support improvements in service quality, increase energy efficiency, and reduce maintenance requirements.
The process of signing and activating the contract experienced delays due to legal proceedings associated with the tender award. With passenger demand growing, CP has indicated the need to recover time lost during these proceedings. Following Council of Ministers Resolution 141-A/2025, of 22 September, CP is evaluating measures to advance the delivery schedule for the new trains and to exercise an option to acquire an additional 36 units for urban services.
