No, there isn't, it was dropped. There is the paid side link via the Bakerloo line but I would bet that the signage says to go out the barriers and across the lawn
Pictures show that the signs direct customers to the Hammersmith & City line[1], District and Circle lines, and the Bakerloo line, the latter being an illuminated sign with arrows changeable by staff on site depending on which way they want customers to go.
Given the Bakerloo line only has one escalator from platform level to ticket hall level (the other one goes down and there is a fixed staircase in the middle) I’m guessing they will want to avoid making this even more busy than it is at present - even at quiet times there are often very hefty queues to leave the platform level - I’m wondering if they’re expecting a lot of customers to be changing to Crossrail via the low level platforms when it eventually opens up to the west, as I’ve not seen any plans for the installation of a third escalator; I suppose the expectation is that the new ticket hall covers this.
[1] Yes, this is typed correctly and doesn’t take into account the fact Circle line trains also go from Paddington (Suburban), presumably an error.
