Popular trainspotter, Francis Bourgeois, was hopping on London’s latest tube service, the Elizabeth line, and taking his massive TikTok following along with him via his iconic fish-eye-lens headset.

However, this turned out to be far more than a regular “riding the tube” video as Bourgeois had a royal encounter when William and Kate, of the royal family, came aboard.

We see a starstruck Bourgeois shake their hands, say hello, and ask what they think of the “Lizzy Line.”

The Elizabeth Line sprint at Tottenham Court Road is quite enjoyable once you get used to it! #trains
