Okay, this isn’t a train. But it’s almost as good. And it’s hilarious.
There’s a cable car, the IFS Cloud Cable Car, that runs over the river. It stops at North Greenwich too. You hop off the Tube, walk five minutes, and suddenly you’re flying above London in a little gondola.
It’s ridiculous. It’s overpriced. And it’s absolutely brilliant for an Instagram story. Use it if you’re feeling fancy. But for the real journey, stick to the Jubilee line.
