Amazingly not accurately checking the loading gauge is exactly what led to a number of news reports today. Here are some quotes from the Reuters article:
France's national rail company SNCF said on Tuesday it had ordered 2,000 trains for an expanded regional network that are too wide for many station platforms, entailing costly repairs.
The RFF only gave the dimensions of platforms built less than 30 years ago, but most of France's 1,200 platforms were built more than 50 years ago. Repair work has already cost 80 million euros.
