It may be one of the world’s most iconic underground rail systems but it’s been living in the dark ages compared to some similar subway systems across the world – until now.
It’s taken 40 years to match the New York subway network but finally, the London Tube is now fitted with air conditioning. 
Last week, the first London Underground service took off with a cool breeze sweeping through the carriage to the relief of thousands of commuters who have complained of stuffy, uncomfortable temperatures during busy times when bodies are pressed up against others in rush hour.
In fact, many commuters have spoken of the ‘unbearably hot’ conditions during the summer months thanks to the deep lines and lack of ventilation; emphasised by the roaring temperatures in 2006 which reached as high as 47 degrees Celsius (116 degrees Fahrenheit).
The new air conditioning service will be present on 40% of the network but there are still grumbles about some deep-lying stations which are still without air con.
“Air-conditioning for the deep-lying lines is a long-term project,” said a Transport for London spokeswoman.
“We are improving conditions on Victoria line trains but there is a lack of space for air-conditioning units on these deep-lying lines. We are looking at various solutions but you have to remember we are dealing with infrastructure which is very old.”
New York’s subway system introduced its first air-conditioned carriages in 1967.
