Plot Holes ( S P O I L E R S )
So many plot holes:
Where did little TImmy suddenly get his custom-made parka and matching boots?
Why didn't the madman-fighter (white guy) die with two swords in him, but the Korean guy (Nam?) could snap his neck?
Why blow up the train and kill everyone, possibly even yourself, rather than take the offered Leadership and stop it someplace where everyone would have a chance at building something... even if they stay in the train for a year or more and let the engine warm it?
In a world (remember that announcer?) where all life has died out, but polar bears may be coming back, how does a lone bear get all the way inland to an Austrian mountain range, where there are no fish not only there, but along the way to fuel his long climbing trek?
Who taught Andy and Timmy how to run the train & how do they eat, sleep and poop when trapped in those work stations? I repeat the latter question for the prisoners locked in drawers?
Why haven't people learned a common language in 18 years of living together?
Who maintains the track and how? In fact, why a train and not just a redesigned building? Someone said "ship," but I assume the oceans are also frozen.
How was this the first avalanche to threaten the train in all these (18?) years?
