In either direction all day Saturday 12 and Sunday 13 May, to allow for renewal of overhead power lines and modernisation of the Byker viaduct.  A replacement bus service, number 900 will be calling at or close to all stations from Monument to Monkseaton, some late night services from Monument will continue to Longbenton (alighting only after Monkseaton to allow people to complete their journeys without changing to a Metro train).  Metro tickets and passes will be valid on the bus service and the driver will sell tickets. Your journey will take longer so please leave extra travelling time especially if transferring between two modes of transport or heading to the football match at St James.
