To prevent cars from ping-ponging - empty - in and out of the same track/region there must be car-orders/waybills for all possible car-kinds that can get routed to that staging track/region.

This Update adds a button that checks the car-kind for car-orders/waybills assigned for OV traffic.   Clicking this button looks at all cars either in, or being routed towards, the selected staging track.   Those routed car-kinds are compared to the car-kinds for the assigned waybills/car-order.

If the car-orders/waybills already assigned cover a car-kind then nothing happens.

If the car-orders/waybills do not cover a car-kind, all available waybills (in the list of waybills) are compared, and if a match is found, and the waybill originates in that staging, that waybill is assigned as OV traffic for that staging.

When the analysis is complete (~ 10 to 60 seconds) a pane appears listing a) the number of car-orders/waybills assigned, and b) the  number of new waybills that you ~may need to create.   Close the pane by clicking the "Close" button.  

New car-orders/waybills will be be those at the bottom of the list of assigned car-orders/waybills.  You may either delete the car-order (delete radio button at bottom of window) or increase the number of cars ordered, up from 1.

There is a simple list that can be printed of car-kinds that ~may be required.   "May" because you may have cars that should depart empty from that staging.  Note the "Print" button in this new pane.

Note that you may need to create more than one waybill for a car-kind.... depending on capacity, volume or length of possible cars or any pool restrictions....such as any assigned commodity.   The car-distributor will check these items and may not assign a car that does not meet these requirements.

OK?
