Class 807 Evero

• First-class driving car: Avanti's side view draws its three window positions nearest the cab as outlines without glass (blanking panels, as on the LNER and GWR first-class driving cars); in photographs all six read as dark panes, so all six are drawn alike
• Seats: Hitachi's 2019 order announcement gave 453; Avanti gives 451, shown here
• Drawing: the cars are the Class 800's measured layout, which Avanti's own side view matches to a mean of 40 mm; the driving-car length and wheel size carry the 800's doubts, and Avanti's side view ends the driving car about 0.2 m shorter than the 800's drawings do
• Colours: sampled from photographs; no paint references have been published. The blue shades from the cab back; it's drawn flat
• Livery: traced off Avanti's small side view (about 56 mm per px); edges to about 150 mm. The black window band is as Avanti draws it
• Car height: the Class 800's drawn height
• Car types: which of the 807's intermediate cars are motored, and which is the trailer, isn't in a cited source; the composite next to the first-class driving car follows from its 49 first-class seats
• Avanti's side view draws the sixth car 1 ft 8 in (0.5 m) longer than the others, an artwork slip; drawn as 82 ft (25 m)
• The pantographs: placed from photographs (scaled by the driving car's doors and windows, to about 0.3 m); no drawing of this class's roof has been published; drawn with no roof well, as photographs show the roof line level over it from the side (set C800F, 13 October 2026), the folded pantograph standing about 240 mm above the roof edge, read off a close platform photograph of 811011 at Paddington scaled by its door: a lower bound, the camera being below the roof; a level, long-lens photograph would measure it
• The cab front: laid on ADPL's sheet 1 outline (side B), within 6 mm; compared with 802304 at Welton (three-quarter) for its shape only
• The driving cars' cab-end bogie: placed at 14 ft 7 in (4,455 mm) from the nose from three side-on photographs (801226, 800017, 801107; they agree within about 50 mm), not from a dimensioned drawing; the wheelbase is drawn 2,600, Beacon's figure for the 803 (set C800B3)
• The bogies: the wheelbase is drawn 8 ft 6 in (2,600 mm), Beacon's figure for the 803 (the photographs read 2,574-2,670); the driving cars' inner bogie centre is drawn at 70 ft 4 in (21,450 mm) from the nose, against about 21,510 (±30) on two long-lens photographs of 802111 and about 21,590 on Beacon's diagram fitted to the doors: not settled, so left as drawn
• The underframes (set UFAT300): from photographs only, no drawing of the AT300's underframe having been published; positions to about 150 mm on the level photographs and 1 ft 0 in to 2 ft 0 in (300-600 mm) on the three-quarter ones; intermediate cars without a side-on photograph of their own drawn with plain panels, or the 805's generator-unit group, as the record's underframe_checked says
• The inner gangway (set JN807): from photographs of 802 and 800 joins, and the 807's seen three-quarter; no drawing of the gangway has been published. The bellows' top is drawn 11 ft 1 in (3,390 mm; the photographs read 3,358 and 3,425), their foot 1,220 (839111; 800020, closer, reads about 1,330); the cables' loops and the brackets are placed from the photographs to about 100 mm
