It was not practical to install lifts or a ramp on the existing footbridge so Network Rail decided to construct a second footbridge, north of the existing one, using modular components. Sensibly NR did not demolish the otherwise-acceptable existing footbridge so this means that Ipswich is one of few stations to have more than one footbridge.
One of the advantages of two platforms is that congestion will be lighter, at least for the mainline trains, although since none of the 'rural' trains are more than three carriages long most passengers use the same footbridge.
This view shows the two-carriage class 156 train that had just arrived from Cambridge on Saturday 24th June 2011. It is clear from the photo that the footbridge provides full protection from the weather. The stairs face south towards the station exit whilst the lifts are furthest away.
These photos were taken on the day of the Railfuture branch meeting in Ipswich.
