Schematic side elevations from each train's recorded dimensions, standing on the same rail. Choose 1× to see them at the stated 10 px per metre, or 2× or 4× to look closer, and scroll or drag sideways; Full screen shows the line-up alone. Drawings labelled indicative are estimates, from photographs and published figures, where no dimensioned drawing has been published. Lengths are over couplers where published; “about” marks one added up from the cars and the couplers between them, as drawn. People are seats plus standing at five per square metre, where both are published; otherwise seats are shown where published, so sorting by capacity puts a seats-only figure among the people figures, and trains with neither come last.
