unverified
- The drawing: Creactive's livery sheet calls itself indicative and several of its dimensions are marked 'TBD'; its scale is good to about 0.5%
- Car 4, the (P)TOS, isn't on the sheet: it is drawn with the TOS's doors and windows, and its roof provision for a pantograph isn't drawn
- Car 3, the TOS(L)W, was built with provision for a universal-access toilet (Siemens, 2016); the toilets announced in 2025 aren't drawn, and which end of car 3 the toilet will be at isn't known
- Door-leaf windows: 1 ft 7 in (470 mm) wide as on this sheet (a photograph of car 421011 gives about 1 ft 6 in (445 mm)); GTR's Class 700 drawing shows about 1 ft 0 in (314 mm)
- Colours: converted from the sheet's printed references; the roof and underframe ('unchanged') and the orange cant line have none
- Wheelbases and wheels: Siemens' Desiro City figures, not printed for the 707
