- British Rail Class 67 Wikipedia, read 13 October 2026the livery's name, who ran it and its years (no colours taken)
- The drawing's bogies: the Mark 4s' and DVT's are the InterCity 225 record's SIG BT41 style; the Class 67's Alstom H-frame bogies are laid out from oblique photographs of 67025 and 67014 (no side-on view or drawing of the bogie was found), so their details are indicative
- Coach order: TfW's carriage layout (January 2026) shows an open standard, the open first, the restaurant car, an open standard with an accessible toilet and an open standard, but not which end the locomotive is at; the drawing puts the locomotive at the first open standard. A 2023 photograph shows set HD01's open first (11323) next to the driving van trailer, so the order has varied
- Doors: one single-leaf door at each end of each coach side, as on LNER's Mark 4s. TfW's carriage layout marks an exit at both ends of every coach, the restaurant car included, where LNER's drawing shows its second doorway as the catering door (drawn so); no source read says whether TfW changed the doors
- Five coaches in every set: TfW's guide says 'seven trains of five coaches'. The first three sets, from 2021, had four coaches and a DVT (RailAdvent, January 2021); no source read says when they were lengthened
- Class 67 length: DB Cargo gives 64 ft 8 in (19.71 m); the 225 Group gives 64 ft 7 in (19.68 m), with 12 ft 9 in (3.88 m) high and 8 ft 9 in (2.66 m) wide
- Mark 4 dimensions: 76 ft 9 in (23.4 m) coaches and 61 ft 0 in (18.6 m) DVT are Eversholt's figures for LNER's Mark 4s, the same type; height and width not given (the site's InterCity 225 drawing measures 12 ft 4 in (3.768 m) high from LNER's artwork)
- The Class 67s: twelve modified for push-pull with TfW's Mark 4s (the 225 Group, an InterCity 225 heritage group, February 2026). Wikipedia, citing Railways Illustrated (June 2024), says TfW bought two of them; the 225 Group's table is unclear on which
- Five cycle spaces 'within separate engine carriage' (TfW's guide): presumably the DVT's van space; not confirmed
- Built: the Mark 4s in 1989-1992 (TfW) and the Class 67s in 1999-2000 (225 Group); left null because the set has two build dates
- Service speed: line speeds on TfW's routes, not 125 mph (201 km/h), limit them; no source gives their timetabled top speed
- The drawing: the Class 67's body, 62 ft 6 in (19.05 m) between the cab fronts at the waist with the buffers 1 ft 1 in (330 mm) ahead of each, is estimated from a near-broadside photograph; its bogies are placed symmetrically from Colin Marsden's 38 ft 2 in (11.63 m) pivot centres (as The 67 Depot, a fan site, reproduces them, with the 9 ft 2 in (2.80 m) bogie wheelbase and 3 ft 2 in (965 mm) wheels); it is drawn 12 ft 9 in (3.88 m) high (the 225 Group; Marsden gives 12 ft 11 in (3.93 m))
- The drawing: the Class 67's cab, doors, ribbed panels, grilles, bands and underframe are measured off a photograph of 67014 through a perspective correction, to about 0.3 m; its other side is laid out differently
- Liveries: photographs from 2022 to 2026 show sets all in black (DVTs 82201 and 82230) and sets in LNER's red and white with a grey and red DVT (82226, 82229); how many sets carry each in October 2026 isn't published, and TfW planned to respray three sets from October 2025 (Find a Tender, May 2025). The black sets are drawn as the default because the January 2026 photograph shows one
- Liveries: the 225 Group (February 2026) lists TfW's 67s in two TfW liveries, two-tone grey, red and black, and all over black with a red roof; others in DB red work the sets too. Which locomotive carries which isn't stated here
- The underframe: shared with the InterCity 225 record's Mark 4s; TfW's TSOD 12315 shows grilles on its skirt that the side drawn doesn't have (the other side, or a different fit; not settled)
- The years of the former liveries come from Wikipedia's class article and the other sources listed, and haven't been checked against a second source.
