Liverpool Lime Street Station is the responsibility of Network Rail.

Network Rail Limited is the owner (via its subsidiary Network Rail Infrastructure Limited, which was known as Railtrack plc before 2002) and infrastructure manager of most of the railway network in Great Britain. Network Rail is an “arm’s length” public body of the Department for Transport with no shareholders, which reinvests its income in the railways.

Network Rail’s main customers are the private train operating companies (TOCs), responsible for passenger transport, and freight operating companies (FOCs), who provide train services on the infrastructure that the company owns and maintains. Since 1 September 2014, Network Rail has been classified as a “public sector body”.

To cope with fast-increasing passenger numbers, (as of 2021) Network Rail has been undertaking a £38 billion programme of upgrades to the network, including Crossrail, electrification of lines and upgrading Thameslink.

In May 2021, the Government announced its intent to replace Network Rail in 2023 with a new public body called Great British Railways.
