Not only is train much better at handling large amount of capacity, it do so with a lower carbon footprint. Looking at the transportation sector in EU-27:

"Within the transport sector, aviation was responsible for 13.2 % of GHG emissions(144.3 megatonnes CO2 equivalent (Mt CO2e) and rail for 0.4 % (4.3 Mt CO2e). The latter refers to the emissions by diesel trains only. This compares with a share of 71.8 % for road transport and a share of 14.1 % for navigation (EC, 2020b)" (EEA Report No 19/2020)

There is a good reason why trains are commonly used between mines and ports. A single train can have around 70-100 of cars, each loaded with 100 tons of Ore. To do the same with planes would be impossible expensive and the emissions would be insane.

The only thing that can get near in terms of capacity and emissions are boats, although that sector is in large need of modernization. They discussed this in an other article about France, since they got several large rivers that could see increased utilization by the transportation sector.

Obviously in both cases, transportation will take longer. I would assume that some delivery services will be exempted when a slower transportation is not suitable.
