According to my watch, we've been riding the train through this tunnel in the Alps for 7 days and 13 hours. Impossible; no train tunnel on earth is that long. Yet it’s no collective hallucination or VR trick—we’re running out of food, water, and soda. A few days ago, some passengers insisted on stopping the train, then trudged back the way we’d come. Soon, they reported through the walkies that there was “no back of the tunnel anymore”(?), then screamed for a long time. We started the train again. Some family trip—guess our only option is to keep moving.
