Narrative:

Atx X was cleared to land on runway 27. Snow removal was in progress about the airport. Tractor 12 called ground frequency (121.9) and requested to cross runway 27 at east (for himself and truck 13). Ground controller instructed truck 12 and 13 to cross runway 27 at east. Ground controller was also working local control and upon checking the runway discovered that truck 12 and 13 were both on runway 27. 1 was eastbound, 1 was wbound. Tower instructed trucks 12 and 13 to exit the runway and report when out. They were also told they had only been given permission to cross the runway as traffic was now on a 3 mi final. Airport vehicles are not properly instructed on the workings of the airport and are very seldom notified when they are in error. For instance, taking an active runway without clearance.
