Walthamstow Central station in North London got some shiny new signs this Friday, thanks to renovation works, but something was amiss...
Commuters quickly pointed out that a crucial "H" was missing from the new station sign.
And so it passed that Walthamstow was briefly re-christened "Waltamstow".
A spokesperson for TfL told BuzzFeed news that the signs were in the process of being replaced by correctly-spelled ones overnight, but some locals seemed happy to embrace the new spelling.
"Waltamstow" quickly settled into the day-to-day tube-chat.
But others demanded their "H" back.
MP for Walthamstow, Stella Creasy, set about winning the missing letter back for her constituency.
In a statement, Jon Fox, TfL's Director of London Rail, said: "I hope customers won't be offended by what was a genuine mistake. We're sorry for what happened and will be replacing the signs as soon as possible."
