I can sense something is wrong… As the train entered the dark tunnel, no-one could hear anything except the constant clattering from the train. We were going faster and faster as the train seemed like it was travelling out of control. Passengers were panicking, screaming with fear and holding on to the bars in the carriage so they don’t lose their balance. The carriage is shaking like a massive earthquake as I feel the train suddenly derail and darkness overtakes. I hold my breath and hope for the best as I hear the train begin to crash into the side of the tunnel.
