Cambrian Line signalling has been centrally controlled from Machynlleth since the 1980s conversion of the route from traditional signalling to a radio-controlled 'RETB' system. On 26 March 2011, the new European Rail Traffic Management System (ERTMS) signalling system went into operational use across the Cambrian Line controlled from Machynlleth. Two days of driver familiarisation followed, with passenger operation commencing on the morning of 28 March 2011. A new control centre has been built on the down side opposite the earlier signal box which has since been demolished.
