Johnston's typeface replaced by... is it Myriad ?
I noticed something similar a few days ago on a diagram in the Paris subway, where Jean-François Porchez's Parisine had given way to something that looked also like Myriad.

I was going to say that the handicapped symbol had been flopped, but maybe this is an American vs. British thing.

Yeah, the typeface is gone. But I see it didn't make big impression here on Typophiles, so maybe I'm oversensitive :)

This would be a major violation of the LT graphic identity standards. If this has been done system-wide (and not just a temporary line change, which would also still be unacceptable...or a prank by a technologically accomplished yet typographically challenged individual) then the LT style guide has been chucked and one of the oldest and most consistent graphic identity standard systems has been destroyed. This is not hyperbole. My feeling is that it is not authorized.

Wheelchair passengers have to wait 'til the end of the line to get out of the Barking line.

Cheers!

Backward, no less. Or should I say backwards? Agh!
