Why cant a train go up hill?
I fail to understand this "logic"
I never said a train
can't go uphill.....but using logic, why would it be a bad idea if a train (some weighing over 5,000 tonnes) was rolling down a decline with failed breaks?
On a level surface, a train has the ability to come to a complete stop.
Conventional freight trains in the US can average nearly 2,000 metres (6,600 ft) long.

On a globe earth, it would be impossible for a freight train to freely stop if part of the train is being pulled down over the curvature (because on a sphere is always moving down and away from you right?)
It would be POSSIBLE for a freight train to stop freely on a flat earth though...
