Sources said that the two Japanese
firms expressed willingness to participate in the supply of the ‘Shinkansen’
train sets. However,
officials sought some modifications of the designs, keeping in mind factors
like cost and suitability for Indian conditions. Also, local weather conditions
are to be considered in the design of such train sets.
“So these
firms, a likely consortium, have submitted proposals with the new designs. The
two companies had approached the executing authority of the Mumbai-Ahmedabad
High Speed Rail (bullet train) project. Discussions took place. This is all
part of the day-to-day work around the project,” the official said.
Each Shinkansen train set will have ten
coaches and can accommodate 690 passengers. The train sets will be modified to
meet Indian conditions, such as harsh hot weather and omnipresent dust.
“The
Japanese air conditioning system in bullet trains is different, suitable for a
maximum temperature of up to 40 degree Celsius only. Necessary modifications to
effectively function at up to 50 degree Celsius are required (in India). A
bullet train operating here would require changes in operations and some technical
modifications to suit Indian demand,” the official added.
Another
factor is that India wants to use ‘bio-toilets’ instead of high-end technical
offerings on Japan’s train sets. Similarly, documentation of instructions on
using facilities has to be primarily in English and Hindi.
“Then, we need to bring down the costs a bit,”
the official said.
According
to the JICA’a loan conditions, only Japanese manufacturers such as Kawasaki and
Hitachi can participate in the bid.
India is
eyeing “slightly lower costs” given modified designs, too. “So yes, some
modifications are being looked at. And bids will come in shortly,” the office
said.
The NHSRCL
(National High-Speed Rail Corporation Ltd) would procure 18 bullet trains based
on Japan’s E5 Shinkansen technology for the Mumbai-Ahmedabad high-speed
corridor.
The bullet
train will operate at a maximum speed of 320 km per hour.
Recently,
Railway Minister Ashwini Vaishnaw shared an update on the bullet train project
on X (Formerly Twitter) by posting a video showing the excavation and
tunnelling work, as well as the use of geotechnical instruments to
overcome these challenges. As per the December progress report, nearly 40
per cent of the project is completed, while in terms of financial progress, it
is 45 per cent.
The
first phase of commissioning - for a 50 km stretch in Gujarat - is
expected in July 2026.
