Where the facts come from
Every factual claim on this site links to its source. This is the full list.
How we checked
Each fact was written in our own words alongside its source. Our build script stores the text of every source and, for each fact, checks that the key words and figures really appear in it. 58 of 58 checks passed when this site was last built (9 November 2026). Where we couldn’t find a named source saying something, we left it out. Where good sources disagree, we say so and give both.
Where sources differ
- Caen’s opening: the 2003 report says Caen’s TVR had been running since 18 November 2002. We say “November 2002”.
- Caen’s last day: Caen la mer says the TVR stopped “at the start of 2018”, so that is what we say.
- Railway Gazette calls Nancy’s line a “guided rubber-tyred trolleybus route”; the French reports call the TVR a tram on tyres. Both are fair: it took power like a trolleybus in Nancy and ran guided like a tram.
