Train carriages could be bomb-proofed to prevent a repeat of the
carnage carried out by the London Underground terrorist attacks.
British engineers have developed blast-resilient rolling stock after
learning lessons from the July 7, 2005 suicide bombings. According to
the Telegraph, they hope to offer advice to the rail industry on how to
protect passengers.
The EU-funded SecureMetro project was launched three years ago to
test designs for over ground and Tube carriages that minimise death and
injury in the event of a bomb attack, the report said. Experts focused
on two main areas, containing the blast impact and reducing levels of
debris that kill and maim and impede emergency services.
According to the report, the research involved a controlled explosion
on a decommissioned Tube carriage. High speed cameras were used to slow
down the blast, allowing its impact on the vehicle’s structure and
interior to be analysed in detail.
A similar test was later carried out on a prototype carriage
specially built to reduce the devastating damage caused by a bomb
detonating inside it, the report said. Blast-protection measures
included tethering down heavy components such as ceiling panels with
retention wire, plastic coatings on windows, and the use of lighter
energy-absorbing materials.
The engineers also investigated dividing carriages with materials
that soak up energy and reduce the impact of a blast wave, the report
added. According to the report, four Islamist suicide bombers took part
in the 7/7 attacks, blowing themselves up on three London Underground
trains and a double-decker bus. Fifty-two people were killed and almost
800 injured. (ANI)
