The only way I see a new “Red Star” is an Amazon sized budget to do it.
I’m going to try to paint a rosy picture here..
Having a 319 doing an all stations up a line at night, stopping for 20 minutes each to unload a cage, then unpack a cage and reload the empty cage…
Alternatively you could offload a cage with a body and depart leaving them to it.. then return to pick them up later (starts getting resource intensive).
So maybe alternative is to no take the cage at all..
take a pre-loaded Amazon locker, filled at the warehouse, off load the whole thing and take back the empty ?
I actually dont think people will object to the 1930’s days of walking down to the goods depot to pick it up, and a local enterprise of local delivery might kick off.
However…
its still cheaper to load up at a hub drive it to a smaller hub, and off load it to a bunch of white van mans to do the last mile.
Unless the government taxes HGVs for carbon emissions, It wont change.
One way that transport is going to be empty, and empty trains cost more than empty lorries.
