Dear MEL Topic Readers,
Your subway wasn’t built for this world
The first subway, the London Underground, opened in 1863, using gas-lit
wooden carriages hauled by steam locomotives, and the first electrified
underground line opened in 1890 in the same city. Then in 1967, the first
air-conditioned subway cars were introduced in New York, and the first
air-conditioned subway system began its service in Hong Kong in 1979. Now, most
subway lines are air-conditioned, except for many of the legendary London
Underground lines that were built ages ago. However, even though susways have
become heat-resistant, they are vulnerable to torrential rainfall events, which
occur more often recently due to global warming. Flooded water rushes down to the
platforms and railways from the entrances and grates, suspending the service and
even causing damage to the operation system. It seems that human-engineered
underground mass transportation systems need another innovation to cope with
human-caused climate events.
Read the article and learn what problems modern subways are facing.
