Thank you for your thoughts.
was there a particular reason for the restriction to which A. Carlotti refers?
It is based on the carload transport system. The shipper will request that the freight be transported by freight car. Occupy one freight car so that the passengers occupy the seat.
And I think it can be used for shunting in yard in future re-combination system.
For example, current systems may load in this way.
wagon #1 | 10t of coal to A |
wagon #2 | 5t coal to A, 5t coal to B |
wagon #3 | 10t of coal to B |
This is not realistic and will cause problems with the re-combination system. One freight car can not be divided in half.
it should be possible to pick up (say) a full load of oil from one location, and then deliver half of it to one customer and half to another.
Certainly I did not think about this. This indicates that the transportation method differs depending on the form of the vehicle.
Some railway wagons are made to unload all cargo at the destination. For example, coal hopper wagon loads coal from the upper side and drops all coal from the bottom.
On the other hand, as A.Carlotti says, tank lorry that transport gasoline may go around several gas stations and unload little by little.
I do not know how the railway tanker unloads but I suppose that all the contents will be transported to the same destination because it is necessary to move to a special facility.
From the above, I think it would be better to divide the configuration into two stages.
mixed_load_prohibition=0 | default. It can mix multiple goods |
mixed_load_prohibition=1 | It can only load the same goods |
mixed_load_prohibition=2 | It can only load the same goods and the same destination |
Note that the destination is the destination of the vehicle.
EDIT: Supplemental addition to mixed_load_prohibition=0
