Trans-Multiversal Express

You’re a passenger on an inter-dimensional train running across space and time. While usually fairly smooth running and home to many high end passengers, the train has suddenly broken down while in the radius of an accumulating supernova that the train was scheduled to pass well within time, but now it seems otherwise. The conductor of the train has also been murdered while attempting to fix the problem. Who murdered the conductor? And how do you fix the train before the supernova implodes and kills everyone on the train? -Hey so this one I let my friend create.
