RAIL Baltica project delivery company RB Rail has invited three supplier consortia to bid for the contract to carry out final design and execution of 25kV ac electrification for the 894km new railway under construction to connect Latvia, Lithuania and Estonia.

This second phase of the procurement process follows an initial tender conducted in 2022, which resulted in four groups of suppliers expressing interest.

The three prequalified consortia invited to bid are:

  • Cobelec Rail Baltica comprising Cobra Instalaciones y Servicios and Elecnor Servicios y Proyectos
  • The Alstom-BMGS-GE-Torpol consortium of BMGS, Bombardier Transportation Baltics, Alstom Transport, GE Energy Power Conversion France and Torpol, and
  • STC Baltic Electrification, comprising Colas Rail, Siemens Mobility, Siemens Mobility Latvia and TSO.

RB Rail will award next year the contract to undertake what it says is the largest single electrification project in Europe.

This will involve the installation of up to 2400 single track-km of catenary, requiring 4350 tonnes of copper wire supported by 50,000 catenary masts. At least 10 substations will be required to supply traction current.

RB Rail appointed a consortium of DB Engineering & Consulting, Idom and Italferr as lead engineering service provider for the energy supply element of the project in 2021. Where possible, power will be provided only from renewable sources.
