The Ordsall Chord provides a direct link between Piccadilly and Victoria stations, allowing trains from Manchester Victoria and the east to continue to Piccadilly. Following completion of the chord, in theory four trains per hour will travel between Manchester Airport/Manchester Piccadilly and Manchester Victoria in each direction, and associated reorganisation of train paths and retimetabling will provide eight trains per hour from Manchester Victoria towards the west via
Chat Moss, and six trains per hour from Manchester Piccadilly towards either Chat Moss or
Bolton and
Preston (trains from both Victoria and Piccadilly stations to the west and north west (Chat Moss, Liverpool, Bolton, Preston, etc.) do not actually pass over the Ordsall Chord, both ends of which lead eastwards, but travel over pre-existing track). The chord is part of the larger
Northern Hub project, proposed by Network Rail in the Manchester Hub Study of 2010. The complete scheme would cost around £530 million to implement. The Ordsall Chord will cost £85 million and will allow around 700 extra trains per day to operate into Manchester. Most through trains on
TransPennine Express (TPE) routes to , and will be re-routed via Victoria rather than Piccadilly but some TPE services to Leeds, Liverpool and Newcastle will continue to run via Piccadilly and will stop at and/or and . The current fast North TransPennine services will operate via Victoria reducing journey times. The full scheme includes new through platforms at Piccadilly and track improvements outside Manchester to allow fast expresses to overtake slower stopping trains, reducing journey times to Leeds by 14 minutes on average and to Liverpool by 17.
Railfreight access to yards in the
Trafford Park area will be improved. Without the chord, such operations would require trains to be run to and then reverse. Concern was raised about the impact the scheme will have on the historic
Grade I listed 1830 railway bridge over the River Irwell, part of the
Liverpool & Manchester Railway's original approach to
Manchester Liverpool Road railway station, (now the site of the
Science & Industry Museum (SIM)), which lies in the path of construction. Detailed designs were presented by Network Rail in November 2012, followed in May by the intended planning application, for submission at the end of August 2013. The plan proposed avoiding the
Stephenson Bridge to cross the river on a
network arch bridge but severing the museum's main-line rail connection immediately to the east of the bridge, ending the museum's out-and-back live steam trips using a replica of one of Stephenson's 1830
Planet-class locomotives. According to Network Rail, "The removal of this connection is not something that Network Rail takes lightly, and we have explored many alternative solutions before reaching the conclusion that the connection would need to be removed to make way for the chord." The museum opposed the alignment, claiming that it would have "a damaging effect on SIM visitors, volunteers and income." ==Construction==
