New software to be installed in metro trains

February 9th, 2012

More than a fortnight after a man traveling on the Blue line (Dwarka sector 21-Noida city center/Vaishali) got stuck in the doors of the metro train, the Delhi Metro Rail Corporation (DMRC) is no closer to identifying the problem. However, it says it will soon be introducing a new software on the Bombardier trains as a possible solution. Said director (rolling stock) HS Anand, “We are conducting extensive tests of the new software along with the manufacturer, Bombardier. Service trials followed by tests on one or two trains will be done under supervision. Thereafter, we plan to implement the software in all the trains,” said Anand.

The decision to install new software was taken even as technical experts continue to remain baffled by the problem. According to Anand, a team from Bombardier, accompanied by representatives of the French company that manufactured the faulty Metro door have been camping in Delhi, testing the train ever since the incident took place. “Despite numerous tests however, the incident couldn’t be recreated,” admits Anand.

Finally, the decision to install new software was taken, he said, adding, “The software will be implemented in three-four trains at a go. So it will take till mid-March for the software to be installed in all Bombardier trains,” Anand added. The doors of Bombardier trains are manufactured in China while the trains are assembled here. According to the director (rolling stock), the new software is expected to address the problem, which technical experts of the Delhi Metro speculate could be an inability of the door controller to identify if the train is moving or at a stand-still.

Meanwhile, the Delhi Metro will soon start a drive to sensitize commuters on metro safety. It plans to deploy volunteers from the Northern Railway Bharat Scouts and Guides in crowded metro stations such as Rajiv Chowk, Kashmere Gate, Central Secretariat, Uttam Nagar, Yamuna Bank and Rajouri Garden from February 21 for a week to spread awareness about safety guidelines. Said a DMRC official, “The volunteers would educate commuters about various issues related to safety while entering or exiting from the train at stations, boarding and deboarding, queuing for boarding etc.” Interestingly, the awareness campaign comes even as the Delhi Metro started making announcements on the four and six-coach trains in stations as well as displaying messages on the passenger information system over the past two weeks.

The incident involving the Bombardier train took place on January 17, when a man got his hand and ankle stuck inside the train door and was carried to the next station. The automatic door, which is supposed to detect any obstacle bigger than 19mm and stop the train from moving, failed to do so.

Delhi Metro to modify signaling and telecommunication software system

January 31st, 2012

The Delhi Metro Rail Corporation is going to modify its Signaling and Telecommunication software system so that the passenger announcement system and the passenger information display system (PIDS) installed at the stations, can automatically give advance information to the passengers whether the next train will be a four coach or six coach train.

This advance information will help the passengers to plan their positioning on the platform accordingly. This, however, requires modification of the sophisticated signaling and telecommunication software which is being done by M/s Alstom in France and M/s Siemens in Germany. This modification is extremely complicated and will take about three months to be implemented.

In addition, as an immediate measure, the DMRC today commenced manual announcements at Rajiv Chowk and Kashmere Gate Metro stations regarding the arrival of four coach or six coach trains. Security guards with loud hailers have been deployed on the platforms at these two stations at the location where a six coach train ends.

Whenever, a four coach train is scheduled to come, they would make announcements in advance requesting passengers to position themselves accordingly on the platform.

The Passenger Information Display Systems (PIDS) at Rajiv Chowk and Kashmere Gate Metro stations have started running messages requesting passengers to stay away from closing doors of the trains. These measures will greatly help and inform the passengers at these interchange stations which are the biggest in the Delhi Metro network with footfalls ranging from 2.5 lakh (Kashmere Gate) to 4.5 lakh (Rajiv Chowk) daily.

In addition, LCD TVs installed at some select Metro stations (Chandni Chowk, Chawri Bazar, New Delhi, Rajiv Chowk, Kashmere Gate, Patel Chowk and Central Secretariat) will also flash messages on door closing of trains very soon. Small films educating passengers on how to step in and out of the trains in a correct manner to avoid mishaps, will also be screened on these TVs.

All metro passengers are advised to kindly stay away from the train doors once the closing/opening operation of the doors commence, for their own safety. Passengers are also advised not to interfere with the door closing operation by obstructing it or putting any object in between the doors. (ANI)

Software glitch hits Metro hard

October 21st, 2010

Thousands of commuters left stranded for hours

Technical snag is becoming a buzzword with Delhi Metro commuters; not one they are particularly fond of. Thousands of passengers had a harrowing time on Tuesday due to software malfunctioning on Dwarka- Noida/Anand Vihar Metro Line. So far, the line has seen the biggest crowds, registering an average ridership of 6 lakh on weekdays.

Train services were affected due to intermittent automatic train supervision (ATS) server failure, resulting in the problem of identification of trains, which are monitored through computers. “Once the train identification numbers are lost, the trains will not be able to move. And this resulted in bunching of trains. The problem was rectified after sometime and services on the line resumed,” a DMRC spokesman said.

The glitch was reported at 11:42 am Delhi Metro said and was rectified by 12.35 PM. However, passengers complained that trains were running slow till late evening.

Shikha Singh, a resident of Netaji Subhash Place, who works with an advertising firm said: “We heard the problem was prevalent since morning. But it’s very chaotic now. It took me almost one more hour than usual. I started my journey at 5 pm from Noida and its 7 pm and I am still travelling. Nowadays the problem is occurring very often,”

Anther commuter, Kshitij Sharma, a web designer who lives in Chandni Chowk, said: “I do not know what the problem was but there were frequent announcements of delays. They were not even mentioning when the problem will be rectified.” During this period, trains between Moti Nagar and RK Ashram were run at a restricted speed.

The major problem occurred due to bunching of trains resulting in thousands of passengers remaining stranded at different Metro stations and trains across the network. The chaos continued throughout the afternoon and persisted till evening.

Metro on Noida-Dwarka route hit by software malfuncioning

October 19th, 2010

Thousands of metro rail passengers here were put to inconvenience during the morning busy hours today when the services were affected for about an hour due to software malfunctioning.

Services on crowded Line 3 (Dwarka Sec 9-Noida City Centre/Anand Vihar), which registers an average ridership of 6 lakh on weekdays, were affected due to “interlocking problem” between Moti Nagar and R K Ashram Metro stations resulting in loss of train identification numbers.

“Once the train identification numbers are lost, the trains will not be able to move. And this resulted in bunching of trains. The problem was rectified after sometime and services on the line resumed,” a DMRC spokesman said.

“Communication network/ technical snag affected train services from 11.42AM to 12.35 PM, on this line,” the spokesperson said, adding the trains between Moti Nagar and R.
K. Ashram were run on a restricted speed during the period.

However, passengers complained the services were affected for more than an hour and they were not able to get trains from Anand Vihar even at 1 PM.

Software issues delay Metro SmarTrip discount

August 31st, 2010

Amidst the recent slew of Metro fare increases, it was a piece of good news: The price of a SmarTrip card was going to be slashed in half from $5 to $2.50.

The price cut was a way to encourage the use of plastic SmarTrip cards as Metro tries to transition from paper farecards.

But now, Metro says that discount — which was supposed to start on Sunday — is being delayed because of software issues.

“Additional programming changes are being required to implement the reduction of the cost of a SmarTrip card,” a recent Metro press release states.

Some riders who thought they’d be getting the discounted cards by now aren’t happy.

“Metro has no information whatsoever about this on the easily reachable parts of its website,” Roger from Oakton writes WTOP. “Just one more Metro screw-up.”

There is no firm date when the discount will begin. Instead, Metro says it’ll start sometime in the early fall.

Using a plastic Metro SmarTrip card instead of the paper version does pay dividends for riders — rail trips cost 25 cents less with a SmarTrip card, and bus trips cost 20 cents less.

Metro says right now, about 75 percent of rail riders and 60 percent of bus riders use SmarTrip cards.

Software glitch reported on first day of higher Metro fares

June 28th, 2010

A software glitch on the first day of Metro’s higher fares allowed riders using paper fare cards at 34 stations to enter for the old fare Sunday.
Metro technicians discovered the problem early in the morning, said Reggie Woodruff, a Metro spokesman. The last fare gate was fixed by 2 p.m., when all stations were charging the higher fare. SmarTrip cards were charged the correct fare throughout the day.

Woodruff said it was unclear why the software, recently added to fare gates in the 34 stations to upgrade the transit agency’s fare collection system, failed to charge the higher amount.

“We anticipated that there might be glitches,” he said. “With all the programming we did for so many stations, it was bound to happen.”

The changes that took effect Sunday raised rail fares by about 18 percent and bus fares 20 percent. Implementing the increases was a challenge because Metro had only about 30 days to test and implement them across its bus and rail systems.
