Pranksters have played a dirty trick on passengers at a bus stop in Kensal Rise after they changed a passcode for TFL’s text information service to a risqué word.

Passengers waiting at the Station Terrace bus stop in Chamberlayne Road were bemused to read they could text the naughty five-digit code to access up-to-the-minute information on bus travel times and routes.

One passenger took to social media to express his shock at the rogue pass code.

Brent resident Calvin Robinson tweeted a photo of the offending sign with the caption: “I don’t think that’s right, somehow.”

TFL has been approached for comment on the sign.
