M201 railway (Croatia)

The M201 railway line is a railway line in Croatia connecting Zagreb Glavni kolodvor (the main railway station of Zagreb) to Rijeka, Croatia's principal seaport. It is a vital transport artery, carrying both passenger and freight traffic between the Croatian capital and the Adriatic coast.

The line traverses diverse terrain, including mountainous regions, necessitating numerous tunnels and viaducts. This challenging geography contributes to the line's scenic appeal but also presents engineering complexities in its maintenance and operation.

The M201 is electrified and is a standard gauge railway. It is part of the Pan-European Corridor Vb, further emphasizing its importance for international transit.

The railway line has undergone several upgrades and improvements over the years to increase its capacity and reduce travel times. Ongoing efforts focus on modernization, including track renewal, signaling improvements, and the construction of new tunnels, aiming to enhance the efficiency and safety of train operations.

The M201 is operated by HŽ Infrastruktura, the Croatian railway infrastructure company, and passenger services are provided by HŽ Putnički prijevoz, the Croatian passenger railway operator.
