Since 2015, it has been prohibited to build level crossings that are too accident-prone. But why not delete the existing ones? Not that easy. Mainly due to significant road obstacles and expensive work costs. “This is a very complex project,” SNCF Réseau underlined. On average, such projects cost a minimum of 25 million euros and can reach 50 million euros.
In total, Île-de-France still has 524 level crossings. Nationally, the figure is closer to 15,000. “Eliminating them requires upstream studies that could take up to two years,” SNCF Réseau reported.
