How the TVR Worked

Ten of our own technical diagrams explaining how the TVR worked: the guide roller and central rail, one axle from above, guided and road modes, a working day’s mode changes, the millimetre tolerances, the 10 km/h braking rule, the two cities’ power supplies and a numbered wear map, finishing with a label-the-drawing test.

Pages: 13 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink.

Every fact is checked against named sources from the French government’s 2003 (CGPC) and 2010 (CGEDD) reports, Railway Gazette International, CBW magazine, Caen la mer, Métropole du Grand Nancy and HESS (checked 9 Nov 2026), and the sources are listed on the pack’s credits page. Things that can change, such as which vehicles run on Nancy’s Line 1, are printed with that date. Where sources give different figures, each is shown with its source.
