I randomly came across the following video showing a Texas train carrying truck trailers (pantech, sem-trailers). I wondered why we don’t use a system like this in Australia.
Perhaps it’s due to height restrictions.
Seems like a good way to reduce heavy road traffic, increase fuel efficiency and reduce environmental impact. With such a vast land and just a few major centers, this would make a lot of sense.
I think that rail is way under utilised in Australia.
