Class 373 (Eurostar e300)

• The crew door (crew-150 job): the window and joints are measured on one square-on photograph (3212, 2018) scaled by the drawing's own light band and yellow line (good to about 4%) and checked on 3216 (2018) by proportion; which panel opens is not known: no photograph shows a closed door outline (none shows the door open), so the door itself isn't drawn, only the visible joints and the window
• The machine-room door (pods-door job): measured on one square-on photograph (3212, 2018) scaled by the drawing's own light band and yellow line, whose heights are good to about 60 mm, so the door's figures are good to about 4% (about 25 mm across it) and placed from the drawn grille's front edge; 3216 (2018) agrees in proportion; no dimensioned drawing shows it
• The power car's grille: positions to about 0.1 m at the front and 0.3 m at the back (the back from oblique photographs), heights to about 50 mm; drawn on the side seen with the cab on the left (3212, 3216, 3007 and a set at Chambery); the other side is laid out differently (3015 at Rainham, 2022: matt dark grey panels with no flutes made out; 3308 at York, 2018, original livery: grey grilles of a finer texture) and is not drawn, so the drawing's turned-round rear power car shows the drawn side too
• Derived from the TGV (general description)
• Sets in service: 8 (Eurostar, ORR, IPEX) against 11 (Wikipedia)
• The drawing: measured from a small 1:300 scanned drawing; windows, heights and the bar car's windows are approximate
• Colours: sampled from photographs (navy and silver vary a lot with the light); no paint specification has been published
• The skirts' depth and panel joints: from the fiche's small 1:300 drawing (to about 100 mm), the grilles' size and the skirts' colour from one photograph (3212 at Albertville, 2018, at an angle); TF drawn as TS; the grilles' presence on the bar and first-class cars not checked car by car
• The drawing's bogies: laid out from photographs (layout only); the passenger cars' Jacobs bogies from a TGV 2N2's of the same Alstom family, since no side-on photograph of a 373's own was found; R9's end bogie (Y 241 P) drawn as a Jacobs bogie; the bogie types (Y 238, Y 240 P, Y 239 P, Y 241 P) from French Wikipedia only
• The drawing's pantographs: only the 25 kV pantograph on each power car is drawn (placed off Allenbach's 1:300 fiche, schematic, and checked on a photograph from HS1); the DC pantographs are left out; its make from French Wikipedia
• The cab's livery and details (set C373C): from one square-on photograph (3212, 2018, about 29 ft 6 in (9 m) away), to about 40 mm on the bodyside and about 70 mm near the nose; the windscreen's extent from 3308's other side (original livery); the nose's length is as Allenbach's fiche (both photographs foreshorten the tip, so neither can test it)
• The joins between cars (set JN373): the seal's width is read on four photographs, none level and square on (10 in to 1 ft 2 in (0.25-0.35 m) at Sevington, 11 in to 1 ft 1 in (0.29-0.32 m) at Rainham, 1 ft 1 in to 1 ft 5 in (0.33-0.42 m) at Saint-Denis; up to 1 ft 8 in (0.5 m) on the oblique Reading slide, which may include an end face; Allenbach's fiche draws the trailers' end lines about 0.25 m apart): drawn 1 ft 1 in (320 mm); the seal's S-shaped jog low down and the car ends' cut-back over each Jacobs bogie are not drawn; the centre coupling (2 ft 4 in (712 mm)) and the power cars' joins (1 ft 1 in (320 mm); about 1 ft 2 in to 1 ft 4 in (0.35-0.41 m) on the Saint-Denis photograph and the fiche) are not re-measured; the corners' 100 mm is an estimate
• The seals' shape (set JN373 round 2): the seal's top is drawn at the lower roof at each join from photographs taken from above and at an angle (Sevington 2012, Saint-Denis 2013) and the Science Museum Group's view of the power car alone, uncoupled; how far it stands proud of the roof is not drawn (no level view of a coupled join's top); the dark diagonal below the waist at the power car joins on both photographs is taken as perspective (both are taken from ahead of the join, where a deeper or tumbled-home surface shifts towards the power car; 3308's square-on view shows the power car's lower end upright), and the car ends' cut-back round each Jacobs bogie's air springs (3214 at Saint-Denis, Reading 1994) is not drawn
• Original Eurostar: the cab's yellow band (round 2): traced on 3216 and mapped by a homography fitted on the number panel, grab plate, nose-cap joint and lamp (within about 60 mm); its foot drawn on the drawn panel's top edge
• Original Eurostar: the yellow band's heights differ between the references: 2 ft 11 in to 3 ft 10 in (890-1,180 mm) on 3308's power car, about 960-1,300 on the 1994 trailers (calibrated on a door) and in the diagram, so the drawing steps 120 mm at the first join; whether the real band steps, ramps or runs level there isn't settled by any photograph found
• Original Eurostar: the rake band's width: about 180 mm on 3308, narrower (60-130) on 3216 taken close; drawn at 3308's
• Original Eurostar: where the orange line starts along the cab's yellow band (drawn from about 12 ft 2 in (3.7 m) back) and whether the trailers carry it (not seen on the 1994 photographs)
• Original Eurostar: the surround margins (95 mm above and below the glass, 60 mm past the outer windows) from one 1994 photograph
• Original Eurostar: R1's and R9's groups from the Commons diagram only (layout only); the bar car's band from the diagram and one 1994 photograph, which also shows its windows about 150-200 mm higher than the other cars', not the 1 ft 4 in (405 mm) the drawing gives them (not changed here)
• 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.
