The Blue Triangle DP191 that Docklands Buses was operating which i mentioned above, was used for an extra bus for the 167 while the Gants Hill roadworks were happening, it mainly just operated between Gants Hill and Loughton instead of Ilford to Debden. It was (and still might be, not sure) on hire to Docklands Buses from Blue Triangle (although these are basically the same companies under Go-Ahead London).
Blue Triangle DP206 (EU04BVD) is now the main allocation for route 804 (Loughton to Debden, with 1 return journey to Buckhurst Hill), as the usual TPL925 (W81 TJU) has been transferred to London General at Sutton for a school route (which is a shame as i really liked this bus!

). The other half of route 804 (Chigwell West Hatch School to Debden) is still operated by the Northern Counties Olympian NV116 (P916RJO).
