Question to the Department for Transport:

To ask His Majesty's Government what assessment they have made of the resilience against flooding and landslips on embankments along the railway lines of (1) South Western Railway, and (2) Great Western Railway.

The Government has not carried out any assessments as described in the Noble Lord’s questions. Train Operating Companies, including South Western Railway and Great Western Railway, are not responsible for managing or maintaining railway infrastructure and have not incurred any expenditure on flood defences or embankment maintenance.

Network Rail has robust plans in place to improve and maintain infrastructure. The Wales & Western Region will see a £2.6 billion asset renewals programme and £1.6 billion invested to maintain existing assets and the Southern Region will see an investment of over £3 billion in infrastructure during the current Control Period to 2029.

It is also addressing severe weather events through comprehensive weather resilience and climate change adaptation plans, focusing on safeguarding assets, embedding resilience into daily operations, and adapting to climate change impacts across both the Wales & Western and Southern routes.

An example is the extensive works being implemented at Chipping Sodbury on the Great Western Main Line to mitigate the impact of flooding from both surface water and groundwater. The work already completed has improved the level of resilience from closure due to rainfall. Network Rail is funding further work at this location during the current Control Period to 2029.
