broad leeway to ignore for the duration of hard times?

The FRA waivers of regulations also allow for:

Verbal quick tie-ups
Lengthened time intervals for required locomotive maintenance and inspections
The movement of defective equipment to the nearest available repair location
only 95% operative brakes for trains leaving their initial terminal
Trains can travel 1,200 miles without an intermediate Class IA brake inspection
Extended haul trains can travel 2,000 miles without an intermediate Class IA brake test
The four-hour off-air time is extended to 24 hours, and to 48 hours with FRA permission
Transfer test requirements are relaxed
The ability to combine two operating trains without additional inspections other than a Class III brake test
Relaxation of yard air source testing and calibration requirements, and of requirements for single-car air brake tests
Relaxation of required testing and calibration of telemetry equipment
