The carriages may do well in a vacuum. The passengers, not so much. If the coveyance in which the passengers are transported are airtight, and filled with life-sustaining air, the contraption could work....much like the capsules that transport cash and papers from the drive-thru lanes at the bank back and forth to the tellers in the bank. I think I’ll pass. My schedule’s not that tight.
That’s written like someone in the late 1800’s would write.
