Stratram would need to overcome a lot of challenges, particularly if squishy humans were among the things being transported into space: the track would need to be around 1, 000 miles long to avoid the kind of instant acceleration that could crush a human, and the train would need a low-pressure vacuum tube to travel through.

The only way to alleviate the pressure is to insert a tube or shunt to drain it.
