Are there any rail connections to Sri Lanka from India?

01-07-2019

There was a rail link to Sri Lanka from India until 1964, with services from Madras to Colombo (the Indo-Ceylon Express). From Madras Egmore passengers took the Rameshwaram Exp. (then known as the "Boat Mail"). The MG track went through Pamban and reached a pier at Dhanushkodi, the southern tip of the island of Rameshwaram and about 27km from the town of Rameshwaram. (The town of Rameshwaram itself was in those days connected by an extension from Dhanushkodi.) Passengers then used a ferry service to cross the 20km (13km?) of open sea at Adam's Bridge (a series of coral reefs), and then boarded the connecting train at Talaimannar in Sri Lanka. The ferry steamer was run by SR (earlier by

What rail fasteners does IR use?
July 18, 2019

IR uses various kinds of Pandrol design fasteners, ERC Mark III (850-1100kg toe load), and ERC Mark V (1200-1500kg toe load) (the latter developed by RDSO). Pandrol 'J' clips, often yellow in colour, which have a lower profile and lower toe load), are used where they need to be removed and reinserted easily and where ordinary clips might interfere

What are the usual neutral temperatures for continuously welded rail? What equipment does IR use for track destressing?
July 18, 2019

IR divides the country into five zones based on the normal temperature variation expected in each region. The maximum rail temperature difference is about 70C (ranging from a minimum of -5C to a maximum of 60C or so -- the rail temperature can be several degrees higher than the ambient temperature. The neutral temperature or stress-free

What kinds of sleepers are used by IR?
July 18, 2019

Cast iron sleepers ('CST-9') are widely used. They are not very suitable for high-speed traffic and so are not usually seen on the mainline BG sections. The earlier 'pot sleepers' were especially prone to problems; newer cast iron sleepers (with ends that have two pockets) are much more laterally stable. Steel trough sleepers ('ST') are very

What kinds of rail joints does IR use?
July 18, 2019

Fishplated joints are the most basic joints seen, on lines where there is no track-circuiting, and no welded rail in use. Fishplated joints are so called because of the use of a fishplate, which is a bar that is attached by means of bolts (fishbolts) to the rails on either side of the joint. Usually there are two bolts securing the fishplate on

Who makes rails for IR?
July 18, 2019

A lot of rails come from SAIL (Steel Authority of India), a public sector company which makes rails at its Bhilai Steel Plant (now the second largest rail supplier in the world). SAIL supplies almost all the 52kg/m rails used by IR, and some of the 60kg/m rails. It supplies the basic 13m, 26m, and 80m rails, and is now manufacturing the 240m and

What types of welding are used for rails?
July 18, 2019

Principally two types of welding are used for rails. One is Flash Butt Welding, and the other is Alumino-Thermic Welding, also known as Thermit(e) welding. A third kind of welding, known as Gas Pressure welding, is used much less often, and a fourth kind, Metal Arc Welding, is very rarely used. In Flash Butt Welding, a strong electric current is
