Shanghai's magnetic levitation train line is running smoothly and according to design specifications, despite recent media reports that the track is sinking, said officials of the line’s operating company.

“Sinking (of the track) is inevitable, given the local soft land conditions,” said Shi Jianqing, a publicity official with the Shanghai Maglev Transport Development Co. Ltd. (SMTD).

“The point is that such sinking has been taken into consideration throughout the project’s proceedings, including stages of planning, design, construction and operation,” he said.

“You can take a look at our daily operation now before judging whether the track’s sinking is serious or not.”

The 30-kilometer-long line, built based on German technologies at a cost of US$1 billion, links the Pudong International Airport to Longyang Lu Metro Station. It only takes about 8 minutes for a maglev train to make a single trip between the destinations, with its peak speed hitting 430 kilometers per hour.

After being put into trial operation in December 2002, the line began offering regular daily trips in late March this year. Two trains now run every 15 to 20 minutes, within the line’s daily service time span of about 9 hours.

Shi was echoed by Lin Guobin, a senior technical engineer with the SMTD.

“It (the track sinking) is no big deal in technical terms, and won’t affect the line’s safe operation,” he said.

The sinking has slowed since it was first detected at part of the track during the line’s testing and trial operation period, and it is still within normal range, according to Lin.

Various technological solutions have been applied to deal with the land’s uneven subsidence, including a Chinese-designed support base that adjusts the track’s height in response to possible land sinking, Lin said.

Reassuring people after safety-related concerns were triggered by the reported track sinking, SMTD is intensifying its efforts to give the maglev line more appeal to the public.

On April 15, the company cut the price of a one-way trip on the line from 75 yuan (US$9) to 50 yuan (US$6), and the price of a round-trip ticket was also cut by half to 80 yuan (US$9.60).

The costs for VIP tickets were also greatly reduced: 100 yuan (US$12) for a single trip and 160 yuan (US$19) for a round trip, compared with 150 yuan (US$18) and 300 yuan (US$36) prior to the price changes.

Passengers can also enjoy a further 20 percent discount when buying a one-way ticket if they are heading for the Pudong airport to catch a flight.

Other measures, like adding more passenger information signs, an information desk and more service staff at the airport are also being added to improve services.

The market response seems encouraging.

The line handled more than 27,570 passengers within only four days after the price change, a significant increase of more than 63 percent compared with the same period the previous week.

Earlier reports had disclosed that on average, the train was operating at only 30 percent of its passenger capacity.
