You thought that was it? Shaun's gone on the road.
Notice anything odd about this trip to London beyond the City/Westminster.
You got it yet? Yep, Watford Station isn't in London. And it gets worse. He's misunderstood the "threat" to the station completely.
Despite what you might think from the name, Watford Station isn't particularly convenient or important- it's at the end of a spur to the Metropolitan Line tube. It's way quicker to get into Central London or anywhere north by using the much bigger and busier Watford Junction (rail) Station.
So a good plan was put together, called the Croxley Rail Link, which would restore a disused section of track and join Watford Junction with the Metropolitan Line. Two new stations would be built, and Watford Station would close, being on a useless spur.
Good project, I think, albeit hard to sell at times of austerity or when your political priority is supposed to be levelling up other regions. So it's not going ahead. That means Watford Station is safe! Even if you think Sadiq Khan has spunked all TfL's money, that's good as far as keeping Watford Station open. If you wanted to attack Khan, you'd stand by the disused line and say "This could be reopened if Khan blah blah".
Not that this would be at all honest. You clocked Watford isn't in London, so you might also have wondered why London was funding it. You wouldn't be the only one. Johnson committed it to it, but there wasn't a pot of money lying about with "Croxley Rail Link" on it, or much prospect of it. The Government and/or Hertfordshire would have to put in a big chunk. They haven't, so no rail link.
But at least Watford Station's safe.
