The Sheffield to Rotherham Tram‑Train Project: Investigation into the Modification of the National Rail Network – NAO Full Report


In May 2012, when ministers approved the Sheffield to Rotherham Tram-Train Scheme, the Department of Transport expected Network Rail’s modification of the national rail network to cost £18.7 million and the tram‑train scheme to be completed by December 2015. By December 2016, the cost of these works had quadrupled to £75.1 million and (at the time of publication of the report) the Network Rail project was expected to be completed in May 2018.

This NAO full report covers:

• the Department’s decision to approve the project;
• cost increases on the national rail infrastructure works and the Department’s
decisions to continue the project; and
• plans for realising the project’s aims.
