The Warsaw–Gdańsk railway is a 323-kilometre-long (201 mi) Polish railway line, that connects Warsaw with Iława, Malbork, Tczew, Gdańsk and further along the coast to Gdynia.

It was built as part of the Prussian Eastern Railway linking Berlin with Königsberg (today's Kaliningrad).

The last single-track section between Mikolajki Pomorskie and Malbork was doubled to two tracks in 1967.

[1] Electrification took place in six stages between 1969 and 1985: Between 2006 and 2014 the line was completely modernised and made suitable for passenger trains to travel at 200 km/h (120 mph) (160 km/h (100 mph) for trains without ETCS) and 120 km/h (75 mph) for freight trains with axle loads of 22.5 tonnes or more.
