That brake in the photo is the typical set up that they sell here for people who want to take a track bike on the road. The aluminum plates press against the seat stays and the brake attaches through the hole in the center of the plates. The lever is quickly removable as well. As John states, you will never see a bike with brakes at the track. Before every professional race, the bikes must all pass a thorough inspection.
