Mansion House Station
|west||Blackfriars||Mansion House||Cannon Street||east|
Note that Mansion House is a terminus for some eastbound District Line trains, and there is a central (westbound) platform where these trains are turned around.
If your train is terminating and you want to carry on your eastbound journey beyond Mansion House, you are probably better off changing at Blackfriars station.
During peak hours, the empty westbound trains are useful for getting a seat.
The exits to this station form something of a rabbit warren, but not anywhere near the scale as at Bank station.
