The three operators plan to pre-qualify bidders by the end of 2020. The three best bids will then be selected for evaluation, and the first train should enter service in December 2025. The value of the contract is estimated at SFr 1.5bn ($US 1.54bn).
SBB will have 106 trains, Thurbo 70 and Region Alps 18. The contract will include options to supply up to 316 trains, as well as maintenance and the installation of ETCS. The trains will need to be designed to operate in Germany and Austria.
SBB is keen to rationalise the number of vehicle types in its fleet, and intends to have just two types of single-deck EMU: this train and a new design to enter service in the period 2037-2048. Double-deck trains will continue to operate in the Zürich area.
