It's August, which means half the capital's transport network must be shut down. This year, it's the turn of Waterloo station: 10 of its 19 platforms have been shut as the station is upgraded to take longer trains.
With knock-on effects at some of the capital's busiest transport hubs, including London Bridge and Clapham Junction, Londoners had braced themselves for chaos.
In the event, though, things didn't start out too badly...
As the day of the upgrade works approached, Londoners feared the worst.
Stations made preparations for an onslaught of miserable commuters.
... and commuters braced themselves.
Waterloo bound - Wish me luck 🤓😫🚆— Gas Safety Shop (@Gas_Safety_Shop) August 7, 2017
As they arrived at the station, things looked bleak.
But then, something confusing happened: the concourse was empty.
Trains were eerily quiet.
Looks like the entire commuting population of Kingston is "working from home", judging by the almost empty 06.59 to #Waterloo.— Liz Shaw (@Liz_Shaw) August 7, 2017
If this is what the Waterloo upgrade works mean then selfishly it suits me 😀 pic.twitter.com/BWRwkgjGe8— Steve Springford (@stevespringford) August 7, 2017
Stations were deserted.
Even buses were less crowded than normal.
Some refused to believe it.
Others quietly celebrated.
But the rest? They were just hoping it'll stay like this.
Also just arrived Clapham Junction from Waterloo 14 minutes late - so not a good sign for the rest of the month or the return journey— USS London 🍊=💩😲👎 (@openpodbaydoor_) August 7, 2017
