Apart from two early morning journeys on weekdays (the 0610 from Coxhoe to Durham and the 0620 from Middlesbrough to Durham) and a single round trip on a Saturday afternoon (1750 from Durham to Middlesbrough and the 1910 return - working off a 22 board), the entire X12 output is now operated by Stockton as of Monday to assist with Belmont’s staff shortages.
Likewise, Belmont’s 7 boards are presently being covered by Darlington for the foreseeable future for the same reason - hence the transfer of 1518 in June when Stockton took on the X66.
