*****No. When the weight data on a car "timed out," it not supposed to be
accepted in interchange - and therefore, in effect, couldn't be
loaded - until it was reweighed. This was often carried out offline
by another railroad, not by the owner (though most car owners seem to
have been relatively conscientious about reweighing cars whose dates
were close to expiring whenever they came back onto home rails).
When empty, cars with expired reweigh dates were routed to the
nearest track scales to be reweighed and restenciled. No doubt there
were times when this practice was overlooked, but not often and not
for long. A sure way to get shippers upset was to have the car
containing their shipment refused in interchange because its light
weight was out of date.
