Question: What happened to the real Sean Fentress?
Question: Why does the train where the action takes place have the locomotive as the last car? When two trains pass each other at one moment, the others locomotive is at the beginning.
BillcowChosen answer: Trains that shuttle back and forth on shorter stretches don't usually turn around at the terminus. They simply go "backwards". So, in one direction the loco is in the front, on the way back it's at the end of the train.
Ioreth
Answer: He died in the train bombing along with all the other passengers. If you're asking what happened to the real Sean Fentress in the alternate time line created at the end of the movie, Colter took over his body and continued to live the life that Fentress had been living.
