Class 221 Super Voyager

• Car lengths: Voith gives a 78 ft 3 in (23.85 m) vehicle; the intermediate cars' 75 ft 6 in (23.0 m) is worked out from Bombardier's 383 ft (116.7 m) five-car unit. Avanti gives a five-car unit as 388 ft (118.35 m), and Wikipedia gives the intermediate cars as 77 ft 8 in (23.67 m); drawn at 78 ft 3 in (23.85 m) and 75 ft 6 in (23.0 m), which add up to Bombardier's 383 ft (116.7 m)
• Car height: taken as the Class 220's (12 ft 4 in (3,770 mm) on Bombardier's drawing); Wikipedia gives 12 ft 4 in (3.75 m)
• Doors: one single-leaf plug door at each end of each side of a car, as on Bombardier's drawing of the driving car and SREMG's description
• Tilt: Bombardier described CrossCountry's original sets as 'tilt decommissioned' and Wikipedia says CrossCountry locked the tilt out in 2008; whether the 12 former Avanti units, which tilted on the West Coast, are run the same way isn't stated in a source read
• Fleet: 36 is CrossCountry's 70 Voyagers less its 34 Class 220s; RAIL lists the 12 ex-Avanti units as 221107 to 221118, and the 2023 contract's table lists only seven of them
• Grand Central's two (221142 and 221143): RAIL, December 2024; EMR was negotiating for them in September 2026
• Seats: the contract, Beacon Rail, Avanti and SREMG all differ (see capacity)
• Grand Central's 221 seats: 276 (Grand Central) or 256 (RailAdvent)
• Drawing: the driving cars are the Class 222's measured DMS, which Bombardier's Class 221 GA matches within a pixel; coach A is drawn like coach F, as Wikimedia Commons's diagram shows it, not from a drawing of its own
• Drawing: Bombardier drew no intermediate car; the MS cars take the Class 222 MS's body, doors and underframe, with seven windows and a small one placed after a Commons diagram (layout only) on the GA's window width and pitch
• Drawing: the underframe equipment and door-button lights are the Class 222's, not checked on a Voyager
• Drawing: CrossCountry's colours are sampled from one overcast photograph (220003, 2010); the roof grey is the 222's, and the orange and yellow cantrail lines are from the Commons diagram only
• Drawing: the livery is the one carried before refurbishment; refurbished units (from 220033, February 2026) carry a new livery (RAIL), not drawn
• Drawing: the HVP bogie is laid out from one near side-on photograph of 221139's front bogie (layout only; the frame stencilled 8 ft 10 in (2.70 m), as Voith's 8 ft 10 in (2,700 mm)); the frame's ends are drawn 1.33 half-wheelbases out (about 1.36 in the photograph) with their top corners cut back, to stay inside the end fairings taken from the 222; the step on the photographed bogie's frame and the pipework aren't drawn, and every bogie is drawn alike; the wheels (drawn 2 ft 7 in (780 mm), as the 222's) aren't published
• Drawing: Grand Central's livery is from 2023 photographs; in October 2023 two of 221142's middle cars were still in Avanti silver, drawn black here
• Drawing: 12 of CrossCountry's 221s (the ex-Avanti units) carry an interim livery (Commons category), not drawn
• Drawing: the cab dome is read off four photographs (220031 and 221140 at Plymouth, 220018 at Durham, the EMT 222 at Leicester), registered by the rail, the roof and the coupler joint, not measured; they agree within about 40 mm; the stretch hidden by the parked wiper's top (10 ft 10 in to 11 ft 8 in (3.30-3.55 m)) is joined, not read; the coupler pocket is placed from the same photographs
• 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.
