Instagram finally launches feature users have been crying out for, for years…

There’s one thing no one wants to do in London‘s stifling 30 degree heat… and that’s take the Tube.

But fear not, travel app Citymapper has introduced a ‘With Air Conditioning’ feature that shows which modes of transport you should take if you want to beat the heat.

Brits have been facing soaring temperatures this month, with highs of 32C in some places.

But as the heat outside rises so too does the heat underground, where temperatrues on deeper-level Tube lines, like the Central and Bakerloo, can reach a stifling 32C – making for a rather miserable commuter-packed rush hour journey.

There are just four tube lines that currently have air-conditioning – Circle, Hammersmith and City, District and Metropolitan.

Other transport options in the capital that offer a breezy commute are the Overground, Northern City line, Elizabeth line, Thameslink and London Trams. 

Citymapper is a handy directions app for those trying to navigate the capital’s complicated travel network, with helpful features such as advising which carriages are busiest and which station exits to come and go from. 

The app gives you a list of suggested routes you can take – which can vary in duration and ticket cost. 

And you don’t have to use the app any differently to access its new air conditioning feature, as when you map directions to a destination it will automatically highlight which routes have air-con for the whole journey. This will be below the suggested routes.

To test its feasibility, MailOnline compared four cross London journeys to regularly-visited areas to see how the air-con routes stand up on price and journey-time. All journeys were mapped for the commute time on a weekday at 7am.

And the feature proved pretty successful, with the journey time and ticket price working out very similar to the non air-conditioned routes.

There was only one journey where going for the air-conditioned route was going to add more than 10 minutes to your journey – travelling from Ealing Common to London Bridge.

The quickest route Citymapper suggests for that journey takes 36 minutes and involves getting the Piccadilly line to Green Park, then changing to the Jubilee line.

But if you want to keep cool, the shortest air-conditioned route is to get the District line to Ealing Broadway, then change to the Elizabeth line to Farringdon, before jumping on the Thameslink to your final destination of London Bridge. But this journey still only takes 47 minutes.

And for one journey, travelling from East Putney to Shoreditch, choosing the route without air-conditioning will actually take you the same amount of time – and cost more. 

Scientists claim the rising temperatures – which resulted in Britain experiencing its hottest summer on record in 2022 – are ‘only the beginning’, so air-conditioned commutes might become more of a necessity. 

However TFL has said there are plans in place to introduce air-con on other London lines, including the Piccadilly, Bakerloo, Waterloo and City and Central.

New designs for Piccadilly line trains mean it could have air conditioning as soon as 2025.

But while the other three lines are due upgrades in the near future, there are no set dates as of yet. 

One of the reasons the majority of Tube lines – Central, Bakerloo, Victoria, Piccadilly, Northern, Jubilee and Waterloo and City – don’t yet have air-con, is that the systems are very old.

The tunnels were built in the Victorian era and have just enough room for the trains themselves to fit through.

And according to charity Engineering & Technology, this means there would be nowhere for the hot air pushed out of the carriages to go. This hot air would just heat up the trains even more.

Building new ventilation shafts would be expensive and the small tunnels don’t have enough room to bolt on large air-con devices.

The lines that have air-con are simply newer, so the tunnels were made large enough to fit the equipment. 

In order to fit the old Piccadilly line tunnel with air-conditioning, new train designs have reduced the number of bogies, structures holding train wheels in place, underneath. This extra space is to be used for air-con systems.  

It comes after the BBC revealed London Underground journeys are on the rise again, and now 90 per cent of pre-pandemic levels. 

According to data from TfL, 91 million Tube journeys were made in April. This compares to 101 million for the same month four years ago in 2019. 

Journeys on the network have however risen by almost 12 million since the same time last year – when the country was still reeling from the effects of Covid. 

Saturday and Sunday are currently off-peak all day, resulting in a reduced fare, with peak times being Monday to Friday between 6.30am and 9.30am and between 4pm and 7pm.

After data showed that Fridays see 28 per cent less Tube customers than Tuesday, Wednesday or Thursday, it was suggested TfL might make travel cheaper either side of the weekend. 

But responding to the claims, a TfL spokesperson said that there were currently no plans to change the timing of off-peak tickets.

Snooping on a partner’s phone is not unheard of in a mistrusting or unfaithful relationship.

But WhatsApp users have joked that cheating has now been ‘upgraded’ thanks to the app’s new Chat Lock feature, which allows users to keep secret conversations locked up with a password.

While it can be used for more innocent purposes such as planning surprises, many have thanked owner Mark Zuckerberg for helping to keep infidelities under the radar.

‘This is so great and wonderful news thanks Mr,’ one Facebook user said. ‘Cheating has been upgraded.’

Yet, a cybersecurity expert also warned that it could be used for ‘nefarious purposes’, with numerous Metropolitan Police officers previously charged and sacked over discriminatory WhatsApp messages.

The Chat Lock feature was rolled out as part of WhatsApp’s continued efforts to keep messages ‘private and secure’.

In a blog post, it said: ‘Locking a chat takes that thread out of the inbox and puts it behind its own folder that can only be accessed with your device password or biometric, like a fingerprint. It also automatically hides the contents of that chat in notifications, too.

‘We think this feature will be great for people who have reason to share their phones from time to time with a family member or those moments where someone else is holding your phone at the exact moment an extra special chat arrives.’

Yet Facebook has been flooded with comments after Zuckerberg suggested that it could be used to hide a ‘secret sauce recipe’ and a ‘fight club’.

Drawing to the 1999 film starring Brad Pitt, one user joked: ‘First rule of fight club…’

Another added: ‘On behalf of CPA (cheating partners association) we commend the great work you are doing.’

Someone else chimed in: ‘Wow, this is absolutely fascinating and groundbreaking! 

‘The realm of cheating has just entered a whole new level of sophistication and advancement. Thank you for enlightening us with this intriguing information.’ 

However, the feature also comes at a time when numerous Metropolitan Police officers have been charged or sacked over discriminatory messages.

Sarah Everard’s murderer Wayne Couzens was found to be in a WhatsApp group called ‘Bottles & Stoppers’ where officers joked about rape. 

Meanwhile, eight Metropolitan Police officers were previously charged following their involvement in another warped WhatsApp conversation. 

The so-called ‘Secret Squirrel S**t’ chat was revealed to contain sexist, racist, homophobic and transphobic profanities. 

With that in mind, Jake Moore, a Global Cybersecurity Advisor at ESET, believes privacy features could be used for ‘nefarious’ purposes, though he acknowledged it is difficult to establish how so, this early on.

He said: ‘It’s difficult to point the finger at who specifically would use the feature but it could suggest nefarious use indeed.

‘Locking chats with a passcode adds a layer of security and improves privacy from prying eyes with physical contact. 

‘Many other privacy focused chat applications are available but WhatsApp is the clear front runner with most people. Although messages are sent with end to end encryption (meaning that such messages cannot be intercepted) the key to unlocking these messages is the device passcode.

‘For more private chats, the ‘Disappearing Messages’ feature in the app adds a much better level of security which wipes messages completely after a certain amount of time.’

To lock a chat, users should open the WhatsApp and tap on the name of a group or one-to-one conversation.

A lock option should then appear, which will prompt users to enter the device password or biometric data to secure that chat. 

To reveal these, a password or biometric data should be applied after pulling down on a WhatsApp inbox.

WhatsApp claims that more options are to be added to this feature over the next few months.  

It said: ‘Over the next few months we’re going to be adding more options for Chat Lock, including locking for companion devices and creating a custom password for your chats so that you can use a unique password different from the one you use for your phone.’

WhatsApp has been approached for comment.
