At first widely used and then strongly neglected in the 2010s, night trains have been making a comeback in environmental debates for a few years. A comeback that echoes the rise of Flygskam, the shame of taking the plane. A phenomenon that appeared in 2018 in Sweden, that is gradually spreading in the West. The idea is to reduce the use of airplanes (especially for domestic flights) in favour of more ecological modes of transport, such as the train, which is proving to be a very good alternative for long journeys. This comeback is illustrated by the great mobilization of the “Yes to the night train” collective and its petition which has already collected nearly 201,500 signatures.
