unverified
- The gaps between cars: not drawn, except the cab-end coupler; the Class 378's printed couplers are used for the rest
- Door and cantrail-line colours from a 2024 photograph (the doorway painting drawing wasn't released)
- The underframe: indicative, from one near side-on photograph per car (the DMOS cross-checked on two more); the side photographed is the one seen with the cab to the right, laid out by distance from the cab end; the PTOS drawn as the MOS (no photograph of a PTOS's underframe found); the front cars show the other side, mirrored, taken as alike from one very oblique view of the side drawn (376029, 2007)
- Built 2004-2005: Eversholt gives only the years of entry into service; no build dates found (Bombardier's painting diagrams are dated 2003)
- How many units are refreshed so far: no 2026 count found (Southeastern, November 2025: the rest 'throughout 2026 and 2027')
