Smart vibration sensor to check rail accidents

Two researchers Alka Dubey and Ashish Verma from Sagar University
have claimed to have developed a smart vibration sensor with
wireless communication to check the required speed on the rail
track. This innovation would reduce accidents of trains.

A SMART vibration sensor with wireless communication for recording
and analysing train vibration has been developed in the country.

Alka Dubey and Ashish Verma of Sagar University brought this
innovation to light, while presenting their paper at the fourth
international Wireless Communication Sensor Networks concluded at
Indian Institute of Information Technology-Allahabad (IIIT-A) on
Monday (Dec 29).

Dubey said that high speed trains are one of the most impressive
developments of the recent years having brought a new degree of
comfort for travelers. These trains posed serious accidents because
of the high level of vibration, which are generated. Therefore to
make the train speed smoother, a smart vibration sensor is
developed. It is a self sensation device equipped with recording and
wireless communication interface.

“One programmed microcontroller 89C52 is used, which records
vibration of trains with real time into memory. There are certain
limits of vibrations, which are acceptable by the railway track.
Beyond this limit the tracks may be damaged, resulting in major
causality,” she said.

“The sensor with microcontroller interface has been designed,
developed and tested at Sagar railway station for reliability of
electronics. The sensor can be accessed wirelessly from a personal
computer or laptop,” she informed.

This sensor is useful for recording the vibrations of trains with
respect to date and time by which investigation team can get the
appropriate reason of accident due to vibration. Smart vibration
sensor does not require wired communication. It can be communicated
with PC or laptop’s using wireless communication.

Railway is an enormous medium of transportation in India. The rate
of rail accidents is high. To decrease the rate of accidents it is
important to know the appropriate reason(s) of accidents. Vibration
induced by train is an important data for accident investigation
team. There are certain limits of vibration from 0 to 100 Hz, which
is acceptable for proper train movement. Beyond this limit accidents
might occur.

Speaking on the occasion, Prof M Radhakrishna said the conference
had achieved another milestone this year by receiving quality
research papers. Prof US Tiwari threw light on role of smart-dust
sensors in coming years.

ISB plans efficiency for S Railway

Chennai-headquartered Southern Railway (SR) has sought Indian School of Business’ help in reducing carbon emissions, enhancing revenues, and identifying areas for investment among others. ISB is likely to submit its report and recommendations by the end of January.

About 15 students in four teams, as part of their experiential
learning programme (ELP), recently visited Chennai to study the
existing advertisement revenue channels of SR, its technology, also
energy usage patterns. SR came into existence in 1951 through the
merger of Madras and Southern Mahratta Railway, South Indian Railway and Mysore State Railway.

The students will apply classroom knowledge to real business issues
of SR and give suggestions on strategic issues. Their mandate is
market positioning, entry strategies, new product development,
growth strategies and talent management among others.

According to Nalin, one of the students involved with the project,
ISB is studying the traction, non-traction, green buildings and
renewable energy segments of the SR. On an average, each ELP project fetches ISB Rs 150,000 from Indian companies.

The report will also be submitted to the United Nations Framework
Convention on Climate Change, an international environmental treaty aimed at stabilising greenhouse gas concentrations, that will enable the SR to trade carbon credits. “Some drivers are consistent with coasting (allowing the train to decelerate after reaching an optimum speed). This reduces the electricity usage by about 30 per cent,” he said.

According to another student Chetan, passenger movements in the SR
can be tapped for additional revenues. “Customised advertisements –
say students, women, officergoers, business community travelling in
trains can be tapped,” said the student pointing out that passenger
profiles change with the route and timing.

The ISB team is interacting with media buying houses for feedback on
their space buying patterns and will conduct trial marketing in

The Southern Railway has already begun a biodiesel generation plant
at its workshop and is also implementing a water management
system. “A few processes just need some tweaking for enhancing their
efficiency,” said Anurag, another student.

Rlys to beat of recession with projects

Rlys to beat of recession with projects 

Indian Railways (IR) which is perhaps one sector of the economy which consumes huge volumes of steel, .coal, electricity and fossil fuels in particular for its operations, have planned to spend as much as Rs.30,000 crores during financial year 2008-09 for upgrading their assets and acquiring new ones which will go a long way in boosting the economy and prevent recessionary tendencies in the economy.Projects which consume lakhs of tonnes of steel, which will go to boost this sector, will of course be at the top. For example the renewal of rails over a length of 2941 kilometres (km) will require 3,39,288 tonnes of steel which should cheer the Ministry of Steel.

Through sleeper renewal over 2382 kms which will require 38.59 lakh pre-stressed concrete (PSC) sleepers this will require 88,200 tonnes of steel. In addition, 5000 tonnes of steel will be required for manufacturing steel channel sleepers during this year.

During the same period, 5294 tonnes of steel bridge girders have already been produced till October 2008 and the total production during the financial year 08-09 the total production during the year will be 8615 tonnes.

The decision of the Railways to acquire coaches, wagons EMUs (Electric Multiple Units), DEMUs (Diesel Multiple Units) will also help the economy because of the large expenditure on them. IR will produce 3000 coaches ( passenger carrying vehicles) this year, which is an increase of 12.5 per cent over the figure of the last year (07-08). Besides, 2873 EMUs,1091 MEMUs (Mainline Electric Multiple Units),216 Kolkata Metro coaches ,and three-phase propulsion system for 200 motor coaches will also be manufactured, with a total outlay of Rs.9200 crores.

Production of diesel locomotives and High-Horse Power EMD (Formerly General Motors) design would be enhanced at the Diesel Locomotive Works at Varanasi. DLW has produced already 152 locomotives.

The production of wheels and axles is also being increased by 6-0 per cent which will reduce imports and hence save foreign exchange.

The Railways have decided to convert 300 ordinary railway stations model stations which will involve both consumption of steel and other materials. Among them will be 23 world class stations.

Another item in which heavy expenditure is involved is the 1000 MW thermal Power station in collaboration with the National Thermal Power Corporation (NPC) at Nabinagar in Bihar at an investment of Rs. 5352 crores.

Indian Railway are also seeking allocation of a coal block with a capacity of 300 tonnes which is proposed to be utilized for setting up of a 2000 MW power plant.

About Rs. 300 crores will be spent during the next three months for commissioning of modern electronic signals at about 400 stations, intermediate block signaling in about 200 block stations and 400 route-kilometres of automatic block signaling.

About Rs.1800 crores will be spent during 2009-2010 for the modernization/ upgradation of signaling systems such as electronic interlocking, centralized panel Operations (500 stations), collision avoidance systems (1800 route kilometers), automatic signaling, centralised panel operations (500 stations), on board train protection/train collision avoidance system (1800 route kilometers) automatic signaling (500 route kilometers) and intermediate block signaling system ( 200 block sections).

Railway electrification target for the eleventh five year plan has been enhanced to 3500 kilometrers. This includes the extension of target from 700 kilometres to 1000 kilometres for the current year. Next year electrification is likely to be undertaken over 1200 kilometrres with an outlay of Rs, 1000 crores which will cover the Ghaziabad-Moradabad section, the Shoranur-Mangalore section, and the Gondia-Ballarshah section.

The last one is a chord between Gondia-Nagpur-Ballarshah and is a very convenient short cut between Gondia Junction and Ballarshah Junction, avoiding the long detour via Nagpur and Wardha.

The high-density network of Indian Railways including the DC-AC conversion in the Mumbai area, is being strengthened for carrying heavier trains and the requirement of funds for these schemes during 2009-10 is Rs.500 crores.

The Mumbai area of more than 330 kilometres has 1500 Volt Direct Current (DC) electrification system since 1925 while the rest of India has the 25,000 Volt Alternating Current (AC) system of electrification. The DC system is being converted to AC and it will take some time before the entire DC system is dismantled.

The acquisition of electric locomotives has been enhanced from 200 to 220 at an outlay of Rs.1740 crores. Process is under way to acquire 200 electric locomotives from Bharat Heavy Electricals Ltd at an approximate cost of Rs. 5.5 crore each.

A factory is being set up at Madhepura in north Bihar manufacturing 100 electric locomotives per year through the Joint Venture (JV) route. Bid process is at present underway.

It is seeking an outlay of Rs.2800 crores towards undertaking telecommunications works till 2011-12.These works include replacement of more than 10,000 route kilometers of overhead alignment.

Now, use your ATM card to get railway tickets

Mumbai: After SMS ticketing, the Western Railway (WR) is set to launch its new ATM-ticketing service. However, in the beginning only long-distance reserved tickets would be issued to the passengers. 

“Initially, we are starting the service with 20 ATM machines. We have tied up with the State Bank of India for this. For the time being, we are only introducing this service for getting long-distance journey reserved tickets,” C P Sharma, WR Divisional Railway Manager (DRM) told Newsline. “One can get the ticket from the State Bank of India ATM centre installed at the Mumbai Central station,” said S S Gupta, chief spokesperson for the WR. “It would just be like an e-ticket.” The cost of the ticket would be deducted from the passenger’s account.

“As a policy decision, all the ATMs installed in the railway premises would have the facility,” added Sharma. The Information Technology arm of the Indian Railway Catering and Tourism Corporation (IRCTC) has already tied up with the other nationalised and private banks to introduce this service on both the WR and the Central Railway network. On the Central Railway network ATMs of Canara Bank would be issuing the tickets to the commuters. “The integration of the railway server and the bank server is in process,” said CR chief spokesperson Shriniwas Mudgerikar.
