A number of strip, map and record areas were identified by the earlier desk-based assessment and geophysical survey (AD Archaeology 2013) and the site divided into zones to investigate potential archaeological features. Initially eight strip, map and record areas were sited within the overall development site, however, two areas (Areas B1 it may also represent a branch line of the Western Way/Derwent Way III or could be an earlier incarnation of the route of the later 19th-century mineral tramline which crossed the site. The line of this single track NNW-SSE mineral tramline and tunnel first appears on the Second Edition Ordnance Survey map of 1896 and by the time of the Third Edition Ordnance Survey map of 1919 was disused. The excavated portion of the tunnel demonstrated that the stone walls survived to a height of c. 3.40m. The results of the investigations are of regional significance as key research objectives as set out in Shared Visions: The North East Regional Research Framework for the Historic Environment (NERRF) (Petts PM2. Early Railways; and PMviii. Industrial intensification 1790-1830. It is noted in the NERRF that ongoing research needs to recognise the role of the North East in the development of the early railways, with several key areas of investigation having been identified. Investigations should focus on the early waggonways and pre-locomotive hauled lines. Existing landscape features along the course of known early waggonways require survey, which if possible, should include railway formations, track beds and gradients. The routes of early railways should be plotted on the HERs of the region, through archival research on early documentary and cartographic sources.
