It makes some sense to use electric or biofuel trucks to move goods for short distances as well as the distance between a facility and an distribution yard, but for long distance I fully agree that we called them multi modal containers for a reason. You can move a container from truck to electric train in seconds, and indeed we already do that for anything that has to travel by ship anyway.
Moving goods vast distances over land extremely cheaply and with zero carbon emissions is a problem that was solved long ago with overhead electrified rail, and it’s amazing to see the lengths we here in North America will go to avoid investing in it.
