Network Rail is delivering the Great Western Electrification Programme to the dates set out in the latest publication of their Enhancement Delivery plan.

This includes completing electrification of the Great Western Mainline to Cardiff Central by December 2018. The recent National Audit Office’s report states that electrification is expected to cost £2.8 billion.

Network Rail have advised the Department that expenditure on the mainline between Cardiff and Swansea has yet to be finalised.
