Seems like an overlook, although the Express is a bit of an odd duck. Relatedly, TFL's pedantry about Underground vs other rail is driving me batty. No one care

Seems like an overlook, although the Express is a bit of an odd duck. Relatedly, TFL's pedantry about Underground vs other rail is driving me batty. No one cares about rail gauge when they travel. Calling the Elizabeth "Elizabeth line" is ugly, and signs in Heathrow pointing to the Underground when the Elizabeth is in another direction entirely are downright insane in a place full of tourists. It confuses me, a Londoner, those poor sods carrying heavy luggage through doomed corridors stand no chance.
