It is on the concourse level within the fare-paid zone next to the station's secondary entrance.

Pleasant were replaced by diesel buses, which again used the station's bus terminal.

Passengers who look out into the tunnel on this section can still see the sloping sides of the original cut, the stumps of lamp posts and trees, and the undersides of four road bridges.
