According to an article,
https://www.linkedin.com/pulse/faster-c ... -notteboom which mentioned about how the adaption of slow steaming method (as in driving cargo ship slower to save money) have widened the gap in speed and price from ship transportation to air and rail transportation.
It said, between Europe and Asia, the slow steaming method mean it take 5 or 6 days more for cargo to finish the route, while faster transportation method are more expensive and doesn't offer the capacity that ship would offer, and thus the author of the article think there is a gap in the transportation industry that could be filled to match the need of high-volume time-sensitive cargos.
What kind of technology would be a more voluminous alternative to air and rail transport while faster than ships?
The article used Eurasia cargo movement as an example which there are Eurasia rail line that can provide rail transportation service, but what are the alternatives for markets like TPAC or TATL that does not have rail connections other than air?
