A Central Line Twitter Q&A went into meltdown when furious commuters hit back at news one of London's busiest Underground lines won't get air conditioning until 2030.
Central Line passengers have been some of the worst hit in the recent heatwave with thousands travelling to and from work in sweltering conditions.
Among angry responses to the 12-year wait were claims that in the current heat Central Line temperatures well exceed the EU limit for transporting cattle -30C.
The #AskCentral Twitter Q&A descended into chaos after @SLT_Enthusiast tweeted the question: "Is there air con on your trains and if so does it usually work?"
Central Line head of fleet Steve Lammin replied: "We've improved ventilation systems on the current fleet. New trains are coming in early 2030, under the Deep Tube Upgrade Program which will be delivered with full air cooling systems."
His answer was met with a barrage of disbelieving tweets by commuters infuriated by the long wait.
Samantha Rodriguez wrote: "Only 12 more years of the central line inferno", while Adam Hodges replied: "We’d have all melted by 2030!"
Twitter user Vincent Flanagan claimed Central Line passengers were being treated worse than EU Cattle: "How do you enjoy travelling on central line trains in 50C onboard temperature heat? Cattle by law aren’t subjected to those temperatures in transit but a few hundred thousand central line users are fair game?"
When asked by getwestlondon why it would take so long to put air conditioning on the Central Line a TfL spokesman explained that the wait was to do with replacing old trains rather than installing air conditioning on the current fleet.
While Central Line trains are due an upgrade, having last been revamped in 1992, they are third in line behind the Bakerloo Line whose trains are 46 years old and the Piccadilly whose trains are an ancient 47.
TfL has reassured passengers that while they'll have to wait for new trains it's "investing millions into improvements on the Central line trains in the meantime."
What's being done to make the Central Line cooler?
TfL has taken these steps to make travelling on the Central Line more bearable in the heat.
- A chiller unit has been installed at St. Paul’s to try to keep temperatures down at the station
- A number of fans across the Central line have been refurbished
- Central line trains have been fitted with reflective film on the windows, which helps to reduce temperatures on the above ground sections of the line, and white film on the roof to help reflect the heat.
Central Line Head of Line Operations, Chris Taggart, said: "We completely understand that travelling can be uncomfortable during periods of hot weather and are investing millions of pounds to make the Tube cooler for customers.
"There are already air conditioned trains on 40 per cent of the Tube network and we are determined to do all we can to help make journeys more comfortable on other lines while investing in solutions for the longer term.
"We have installed a chiller unit at St. Paul’s to try to keep temperatures down at the station, and have refurbished a number of fans across the Central line. We have fitted Central line trains with reflective film on the windows, which helps to reduce temperatures on the above ground sections of the line, and white film on the roof to help reflect the heat.
"During this extreme and prolonged period of hot weather, we advise customers to ensure they have water with them when they travel in order to stay hydrated, offer a seat to those who may need it, and, if they feel ill, to contact a member of staff at the next station."
