The fleet, which is due to enter service from 2023, will comprise electric locomotives and Talgo 230 coaches.
DB says it plans to deploy the fleet on Berlin – Amsterdam, Cologne – Westerland (Sylt), and Hamburg – Oberstdorf services.
DB board member for passenger transport Mr Berthold Huber told the German Press Agency (DPA) this week that 200 new trains will join the long-distance fleet by 2024, representing a total investment of around €6bn.
This year DB expects 15 ICE 4 high-speed trains and 10 sets of Bombardier IC2 double-deck coaches to enter service.
Last September DB announced the acquisition of 18 additional seven-car ICE 4 sets and 50 intermediate vehicles to lengthen trains already on order.
Huber says DB Long Distance carried 145 million passengers in 2018, an increase of 3 million compared with 2017, although punctuality was well below target.
