Metre-gauge railway in the context of "List of railway stations in Zurich"

Mettupalayam railway station (station code: MTP) is an NSG–4 category Indian railway station in Salem railway division of Southern Railway zone. It is a railway station located in Mettupalayam, a suburb of Coimbatore district in the Indian state Tamil Nadu. It is one of the important railway stations located in the Coimbatore District, because the Nilgiri Mountain Railway to the hill station of Ooty starts from here. It is the connection between the metre-gauge Nilgiri Mountain Railway and the broad-gauge main network of Indian Railways. It recently celebrated its 150th anniversary.

The Grand Trunk Express operated from Mettupalayam to Peshawar from 15 October 1929 and was extended to Lahore from 1 March 1930. Later that year, on 1 September 1930, it was changed to New Delhi to Chennai, which remains the case till today. The Tea Garden Express ran in metre gauge between Ooty and Mettupalayam and broad gauge between Mettupalayam and Cochin Harbour Terminus. Post-Indian independence, the Ooty–Mettupalayam trip was cut off, and the train ran as No. 565/566 between Cochin Harbour Terminus and Mettupalayam since the 1970s. Today the Nilgiri Express (also known as the Blue Mountain Express) covers Chennai to Mettupalayam and acts as the link to Ooty. Nilgiri Express used to be the main portion of Bangalore Mail, Island Express, Malabar Express and Mumbai–Coimbatore (through coach bifurcate/amalgamate to Chennai–Mumbai Mail).

The railway from Piraeus to Patras was a 230-kilometre-long (140 mi) metre-gauge railway line in Greece that connected the port of Athens, Piraeus with Patras in the Peloponnese peninsula, via Athens "Peloponnese" central station and Corinth. It was opened between 1884 and 1887. Formerly one of the main lines of the Greek railway network, it has now largely fallen into disuse. It has mostly been replaced by the Athens Airport–Patras railway, a new standard-gauge line whose first section opened in 2004 and which remains under construction between Aigio and Patras. The 13 km (8.1 mi) section between Piraeus and Agioi Anargyroi, a northern suburb of Athens, has since been removed and replaced by the corresponding section of the upgraded Piraeus–Platy railway. As of 2020, the only sections in operation are the 22.5 km (14.0 mi) section between Agioi Anargyroi and Eleusis, and the 7.3 km (4.5 mi) section between Rio and Patras.
