Thanks for a good movie, but it made me wander about a few details.

Map in snowpiercer:
I measured the length on an online map. I got a result of 92 000 km.
Since the train never stops and it does go around it's entire trajectory in a year, the average speed of train is.....
10,6km/h

But, In movie, they said, the track is 438 000 km...
Well, in that case, the train is speeding throughout the world at: 50km/h...

SPEED IS KEY!!!
