Under the new organisation Network Rail, along with functions from the Rail Delivery Group and Department for Transport will be absorbed as the government delivers what has been described as “the biggest change to railways in 25 years” and aims to lay out a 30 year strategy for the sector. GBR is expected to deliver £1.5bn in savings a year after five years as a result of “increased purchasing power and economies of scale, and make it easier and cheaper to plan maintenance, renewals and upgrades”. The Williams Review, chaired by former British Airways boss Keith Williams, was launched in May 2018 and triggered by chaos created by timetable changes that year and the failure of the East Coast franchise. The White Paper states that “failings at Network Rail were central to the collapse of the timetable” and previous reforms had failed to control costs.
