You’re right about the signage. Elizabeth line looks like the tube, feels like the tube, but technically isn’t the tube. So there’s no signs to other tube line

You’re right about the signage. Elizabeth line looks like the tube, feels like the tube, but technically isn’t the tube. So there’s no signs to other tube lines. Just signs on how to get to the tube which feels weird because you thought you were already on the tube. It would be better to explicitly spell out directions to what tube lines are available.
