 During the COVID-19 pandemic, several TGV trains were transformed into mobile hospitals, in order to transport critically ill patients from overwhelmed hospitals in the East of France to hospitals in the west.Every coach allows for up to 6 patients, allowing for the transport of several dozen patients, attended by a staff of 50 medical workers.Although the train moves at high speed, it accelerates and decelerates smoothly, allowing for medical procedures to be performed during transport.
