Deutsche Bahn (DB) is planning to invest €41bn ($51bn) in its rail operations from 2010 to 2014.
Germany's state-owned rail operator is expected to spend 75% of this amount on rail network and station modernisation and the rest on acquiring new trains.
DB technical director Volker Kefer said the company plans to acquire 300 high-speed ICx trains to succeed the current ICE model.
The investments are intended to improve travel times and increase train reliability and punctuality, according to AFP.
DB owns 34,000km of track in Germany and transports more than seven million passengers each day.
