 The planning, supply, installation and commissioning of the tunnel control systems, which are to be controlled from a control centre at Pollegio, has been contracted to Tunnel Control Systems.The awarding of these contracts was not without controversy; a pair of appeals were subsequently upheld by the Federal Supreme Court of Switzerland regarding the awarding process.At one point, it looked as if completion of the Ceneri Base Tunnel may be delayed as a consequence of legal disputes.
