Regarding the schemes eponymous nickname, Bozza said "If anyone still
persists in calling them 'Boris bikes' rather than Santander I will
change my name to Santander Johnson."

I expect the name could be as long lived as :

or even:

Any older offerings with a vague transport connection?

William Baker, of Baker Street - partial (and unwitting) contributor
to the Bakerloo line name. Started laying out the street in 1755

That beats Lord Liverpool (after whom a Street is named) or William
Praed. But St James's Park dates to 1603, and Leicester Square to 1630.

I'll offer St Pauls's and 604 as the oldest yet. Can anyone beat that?

London Wall?
Aldgate?
Aldersgate?
London Bridge?
Tower Hill?
City Thameslink?
I'm not sure I understand the question.

Transport things named after a person from long ago.
