I last explored parts of Heathrow in 2017, a trip that had to be aborted due to issues with the trains.

So it was off on the Elizabeth Line to Terminal 5:

I then got a Heathrow Express train to Terminals 2/3:

and a bit of a walk to Terminal 2:

and yet another train to Terminal 4:

From there, an Elizabeth Line to Bond Street and the “other” exit that we’ve not used by Hanover Square:

From there it was a short walk to Oxford Circus and the Bakerloo Line:

Next stop was Elephant & Castle, somewhere I’d never been to. Shame the nice entrance is covered up:

Another entrance was better looking:

Nearby was the Faraday Memorial and a third entrance:

From there, it was a tube to London Bridge and a fast train home.
