> What's expensive is infrastructure. Seems to be the case: > In 2011-2015 the Warsaw-Gdańsk-Gdynia route underwent a major upgrading costing $3 billion, partly funded by the European Investment Bank, including track replacement, realignment of curves and relocation of sections of track to allow speeds up to 200 km/h (124 mph), and modernization of stations. Note it was an "upgrading" of existing tracks.
