Platform 1 at St. James is currently out of use due to the escalator renewal work, so only platform 2 can be used by passenger services. On most days during December, some of the trains that would normally return to the depot after working Regent Centre/Monkseaton - Pelaw services are being kept out for the Christmas shoppers. Some of these trains are extended to St. James, and in previous years they would wait in the other platform for the regular service train to depart, then follow it around the Coast. However, with only one platform being in use, the extra train will terminate at Monument platform 4, shunt out of service to St. James platform 1, out of service to Monument platform 3 then in service around the Coast.
This is the reason why on Sundays trains are often held in the tunnel between Monument platform 4 and St. James. Under normal timetabled running on a Sunday, there will be one train in the platform at St. James and the train behind normally arrives into the opposite platform. The first train then departs for Monument while the second has a 15 minute wait at St. James. However, with only one platform in use the train terminating at St. James has to wait for the train in front to clear platform 2, which can cause delays.
