There were two additional mainline stations serving the city at one stage.
The station is the oldest mainline station in the world.
Unlike the other two stations on the railway, there was no original mainline station here.
At this part of their route they became road tunnels under the mainline station as it expanded over the years.
These services run from underground platforms below the mainline stations.
It was managed and branded separately from the mainline station.
Once many were closed, people just used cars rather than go to the nearest mainline station.
The mainline station is only closed between 1:30 and 3:00.
The mainline station remained open during most of this work.
But the value in serving three major mainline stations by the line later led to the abandonment of this proposal.
