Reforms and upgrades

Outdated communication, safety and signaling equipment, which used to contribute to failures in the system, is being updated with the latest technology. A number of train accidents happened on account of a system of manual signals between stations, so automated signaling is getting a boost at considerable expense. It is felt that this would be required given the gradual increase in train speeds and lengths, that would tend to make accidents more dangerous. In the latest instances of signaling control by means of interlinked stations, failure-detection circuits are provided for each track circuit and signal circuit with notification to the signal control centres in case of problems. Though currently available only in a small subset of the overall IR system, anti-collision devices are to be extended to the entire system. Aging colonial-era bridges and century-old tracks also require regular maintenance and upgrading.
The fastest trains of Indian Railways, Rajdhani Express and Shatabadi Express face competition from low-cost airlines since they run at a maximum speed of only 150 kilometres per hour (93 mph). At least five corridors are under consideration for the introduction of high speed bullet trains to India with expert assistance from France and Japan.

IR is in the process of upgrading stations, coaches, tracks, services, safety, and security, and streamlining its various software management systems including crew scheduling, freight, and passenger ticketing. Crew members will be able to log in using biometric scanners at kiosks while passengers can avail themselves of online booking.Initially, various upgrade and overhaul work will be performed at more than five hundred stations, some of it by private contract. All metre gauge lines in the country will be converted to broad gauge (see Project Unigauge). New LHB stainless steel coaches, manufactured in India, have been installed in Rajdhani and Shatabdi express trains. These coaches enhance the safety and riding comfort of passengers besides having more carrying capacity, and in time will replace thousands of old model coaches throughout Indian Railways. More durable and conforming polyurethane paint is now being used to enhance the quality of rakes and significantly reduce the cost of repainting. Improved ventilation and illumination are part of the new scheme of things, along with the decision to install air brake systems on all coaches. New manufacturing units are being set up to produce state-of-the-art locomotives and coaches. IR is also expanding its telemedicine network facilities to further give its employees in far-flung and remote areas access to specialized medicine. IR has also piloted Internet connectivity on the Mumbai-Ahmedabad Shatabdi Express, powered by Techno Sat Communications It is estimated that modernisation of IR and bringing it up to international standards would require over US$200 billion in new upgrades and investment.

Sanitation in trains and stations throughout the system is getting more attention with the introduction of eco-friendly, discharge-free, green (or bio-) toilets developed by IIT Kanpur. Updated eco-friendly refrigerant is being used in AC systems while fire detection systems will be installed on trains in a phased manner. New rodent-control and cleanliness procedures are working their way into the many zones of IR. Central Railway's 'Operation Saturday' is gradually making progress, station by station, in the cleanup of its Mumbai division.

Augmentation of capacity has also been carried out in order to meet increasing demand. The number of coaches on each train have been increased to 24, from 16, which increased costs by 28% but increased revenues by 78%. The railways were permitted to carry 68 tons per wagon, up from the earlier limit of 54 tons per wagon, thereby cutting costs. The turnaround time for freight wagons was reduced from 7 days to 5 by operating the goods shed 24X7, electrifying every feeder line (this reduced time spent switching the engine from diesel to electric or from electric to diesel). Reducing the turnaround time meant that the Railways could now load 800 trains daily, instead of 550 trains daily. The minimum tonnage requirements were reduced allowing companies to unload their cargo at multiple stops.[
