2. Cité du Train
If the Cité de l’Automobile may be the best car museum in the world, the same honour applies to Cité du Train, which is certainly the biggest in the world.
From the earliest locomotives in the 1840s to the cutting-edge TGV, you will lose count of the number of trains lined up.
What’s also cool is the way the Cité du Train manages to make the exhibits modern and interactive, without skirting around the sort of technical information that the real enthusiasts and engineers will come for.
In the newly renovated building displays go into depth explaining how steam, diesel and then electric locomotives function.
You can also look inside a steam locomotive to fully appreciate its mechanisms.
