What's also odd is that the 'Overground' flashes on LUL car diagrams
inside trains do not have the BR/NR double arrow but those affixed to
station diagrams do. And those on station diagrams are being placed
against every possible LU/LO interchange and not as per the design
manual. EG a Bakerloo Line NB sign at Baker Street should show LO
interchange at Queens Park (for Euston), Willesden Junction (for NLL/
WLL) and Harrow & Wealdstone (for NB DC line) yet the amending
stickers shown at evert 'joint' LO/LU station.
