- Build years and numbers of each batch: B90 22–44 (1991–92) and B2K 01–16 and 91–99 (2001) from British Trams Online alone; B92 45–90 (1992–95) also given by Rail (October 2025)
- Seats today: the 2001 drawing gives 68 a car (64 fixed, 4 tip-up); British Trams Online gives 52 for all three batches and railway-technology 70; no source says whether later changes cut them
- The B90 is drawn as the B92: no B90 drawing has been published; DLR's maintenance schedule treats the B90, B92 and B2000 as comparable, and photographs of B90s 24 (2009) and 26 (2023) show the same layout and front
- The bogies: drawn as the B92 sheet outlines them below the body (the motor and articulation bogies alike, as it draws them); no photograph found shows them side on
- All-over adverts (e.g. a B92 in 2003): no source found for the all-over adverts or their years: the one cited before, British Trams Online's p=6094, is about Edinburgh Trams' early liveries (set TF, 20 October 2026)
- 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.
