Transport Initiatives Edinburgh (TIE) oversaw the construction of the Edinburgh Trams which began in 2008 with the diversion of underground utilities in preparation for the track laying and utilized street running which is the routing of the tramway track to run directly along public streets.
Since construction started in 2008, the Edinburgh Trams project was criticised for delays to the infrastructural works, in particular the closure of Princes Street. Following the transfer of Ties responsibilities, the tramway contractor Bilfinger Berger spoke out about Ties management of the tram project and took the view that Tie had a poor risk management strategy and that it had failed to organise the necessary construction work to move the underground utilities prior to tramway construction. This article is about railways running on public roads.
