Car Types in FYM …..
Cars with a Primary Index can be set explicitly on any un/load siding using FYMMap. This means that such cars can be created on map (on that siding) or created via Local Delivery. Cars can only be created on maps where their primary index is explicitly defined.
So the car ‘Flat, Garbage can un/load on any siding where the car Flat, 60’ can un/load – but it cannot be created there.
Mechanical/Physical variation cars cannot be set explicitly using FYMMap. They can be created on sidings/maps where their ‘Primary Link’ is defined. They will also un/load on any siding/map where their ‘Secondary Link’ is defined.
All Secondary Indices and Links have been changed to ‘1’ (No Secondary).
