Class 345

• The aerials and the pantograph car's roof box (roof3 job, 11 October 2026): sized off TfL's data sheet (the aerials on p. 3, about 25 mm; the box on p. 2's nine-car diagram, about 72 mm, both pantograph cars agreeing to 50 mm, its height sized against the pods); the aerials' fin shape and which way they face from the photographs (345068 at Paddington and 345065 at Westbourne Park, 2024; 345002 at Ilford, 2016), whose angles and height:length agree with TfL's widths; fin 1's TfL widths narrow faster than the photographed edges allow (drawn within 9 mm of them); the 2024 photographs show more aerials than TfL draws (a pair ahead of the cab pod, another just behind it), not drawn; the pantograph and the box are placed off TfL's p. 2 (about 72 mm a pixel, their ends to about 50 mm; p345 job, 11 October 2026), the photographs from above too oblique to check them along the car; a shallow pantograph well TfL p. 2 may show isn't drawn
• The roof pods (pods-door job, 11 October 2026): lengths, positions and their 105 mm height measured off TfL's rendered car views (about 25 mm a pixel; the PMS's off the nine-car diagram, about 72 mm); the photographs (345065 at Westbourne Park and 345068 at Paddington, 2024; 345007 at Stratford, 2017; a centre car at Stratford, 2024) agree on where they stand but are too oblique to measure; the ends' 80 mm rounding is read off 345065; the pods' foot line on the roof's curved side and their hatches aren't drawn
• The underframe (job c345): cases measured off TfL's rendered views (about 25 mm; the PMS 70 mm, off the nine-car diagram) and checked against photographs only for the DMS; their pale or black tone is the sheet's
• The cab (job c345): the photographs are rectified on the bodyside's plane, so parts on the cab's curved sides (the side window, the front corner's panel edge) are good to about 50 mm along; the cab door is 2 ft 0 in to 2 ft 1 in (620-640 mm) in the photographs; TfL's side view draws about 870 between lines at the panel joints either side of it (2 ft 7 in (790 mm) on 345007); the cab roof's rise behind the visor is TfL's (about 90 mm over the saloon roof, 5 ft 3 in to 9 ft 6 in (1.6-2.9 m) from the nose, measured to about 25 mm); 345065 at Westbourne Park (2024) confirms the step but, being slightly oblique, can't size it
• Tare weights: TfL's car weights add to 316.5 t (2 x 37 + 2 x 31.5 + 30 + 39 + 2 x 37 + 36.5), not its printed 318.5 t for the nine-car train (data sheet, pp. 1 and 3); MS1's 30 t may be a misprint, being lighter than the trailer TSW's 36.5 t though it has four motored axles
• The gaps between cars (2 ft 4 in (716 mm), measured on Bombardier's drawing of the 720) agree with TfL's 345 sheet, whose side views draw the gangway 2 ft 3 in to 2 ft 4 in (690-707 mm) proud of each No. 2 body end (±25 mm); with them the drawn train is longer than its cars' printed lengths add up to, by 2 ft 4 in (716 mm) a join
• Wheels 2 ft 8 in (825 mm) new: Wikipedia's Class 345 page, citing Bombardier's 2018 bogie portfolio presentation (not seen), taken for every FLEXX Eco Aventra
