unverified the drawing's wheels and wheelbase: the diagrams draw them inconsistently (wheels 830-925 mm, wheelbase 2,570-2,720 mm); drawn at their means, the drawing's livery: the arrows and vignettes follow the guidelines' rules and their Class 314 sheet, and the cantrail line's height (about 3.18 m) and the grey roof's edge (about 3.35 m) are estimated from a photograph, the drawing's windows: from diagrams of 1986 and 1988; the accessible toilets fitted in the 2018-2020 upgrades may have changed the windows of one driving car, the drawing's front: the diagrams show the 1986 front with its gangway, removed in 2005-2007; drawn as the body's front without it, the drawing's cab side window: drawn as the 1986 diagrams draw it (2.04-2.83 m above rail); photographs of 318257 (2026) show it deeper since the cab was rebuilt, to about 1.7 m, the drawing's bogie frames and underframe equipment: a plain schematic, not drawn from a source (the diagrams draw only the wheels)
