What kinds of signals (semaphores, lamps, etc.) does IR use?

14-07-2019

IR uses several kinds of signals. Semaphore signals have generally given way to colour-light signals although there are still many places with semaphore signalling in use. Semaphore signals are the older style signals seen widely throughout the country, where each signal has an assembly with an arm mounted on a mast, where the arm can move through two or three different positions at different angles, each position providing a distinct signalling aspect. Very early in India's railway history, two-position lower-quadrant semaphore signals were the most prevalent. Around the 1930s, however, the introduction of American style power signalling equipment in some areas resulted in three-position

Are there any rail connections to Sri Lanka from India?
July 19, 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

Where are the oldest rails to be found on IR?
July 19, 2019

Most of the very old tracks have by now been relaid and renovated, so that it is very hard to find very old rails. Good bets are the meter-gauge and narrow-gauge lines that don't see much traffic. Abandoned lines (such as at the Bombay Port Trust railway) also sometimes have very old rails left intact. The Bombay Port Trust railway tracks between

Sometimes the sides of rails appear to be painted. Why is this done?
July 19, 2019

Normally, rails do not need to be painted as the expected life span resulting from the effects of wheel wear and fatigue is such that corrosion is not a significant problem. In some areas, however, corrosion of rails, especially on the inside of the rail foot below the liners, or on the sides, can be quite severe, and may result in the need for

What are the small vertical sections of rail that can be seen embedded in the trackworks or a little distance away from the tracks every so often?
July 19, 2019

These small vertical pieces of rail (or other structures such as a small cement post), usually painted yellow or white, are monuments or vertical datum indicators. They have marks on them that indicate the correct intended height of the rail head at that location on the track. When track maintenance crews adjust track for its level, they use these

What is included in the 3-tier maintenance regime?
July 19, 2019

The three-tier system divides responsibilities for track maintenance as follows: 1. On-Track Machines (OMU). Mechanized maintenance (see above) including systematic tamping, intermediate tamping, shoulder ballast cleaning, ballast profiling and redistribution, track stabilization, and periodic deep screening of ballast. 2. Mobile Maintenance

Does IR use mechanized means for track laying and maintenance?
July 19, 2019

IR has used some track-laying equipment, but much track is still laid manually. A lot of track maintenance is also done manually, with a veritable army of gangmen that are out 'on the line' to inspect track and fix problems. There is, however, a big push to mechanize track maintenance -- the target being complete mechanization by 2012. Tie
