Question to the Department for Transport:

To ask the Secretary of State for Transport, when the wall outside Liverpool Lime Street Station which collapsed on 1 March 2017 was last surveyed by Network Rail; and how often Network Rail surveys the (a) rail bridges, (b) cuttings and (c) tunnels leading to Liverpool Lime Street Station.

Network Rail last undertook detailed examinations of the affected slip area on 7 December 2014, and a further visual examination on 25 December 2016.

The majority of cuttings leading into Liverpool Lime Street Station are inspected every two or five years depending on their categorisation. Rail bridges and tunnels, however, are categorised individually and have different inspection regimes tailored to the age and condition of the structure.
