A railroad carrier and its officers and agents
(1) may provide sleeping quarters (including crew quarters, camp or bunk cars, and trailers) for employees, and any individuals employed to maintain the right of way of a railroad carrier, only if the sleeping quarters are clean, safe, and sanitary and give those employees and individuals an opportunity for rest free from the interruptions caused by noise under the control of the carrier; and

49 USC 21107 - Maximum duty hours and subjects of collective bargaining

The number of hours established by this chapter that an employee may be required or allowed to be on duty is the maximum number of hours consistent with safety. Shorter hours of service and time on duty of an employee are proper subjects for collective bargaining between a railroad carrier and its employees.

49 USC 21108 - Pilot projects

(a) Waiver.— 
A railroad carrier or railroad carriers and all labor organizations representing any class or craft of directly affected covered service employees of the railroad carrier or railroad carriers, may jointly petition the Secretary of Transportation for approval of a waiver, in whole or in part, of compliance with this chapter, to enable the establishment of one or more pilot projects to demonstrate the possible benefits of implementing alternatives to the strict application of the requirements of this chapter to such class or craft of employees, including requirements concerning maximum on-duty and minimum off-duty periods. Based on such a joint petition, the Secretary may, after notice and opportunity for comment, waive in whole or in part compliance with this chapter for a period of no more than two years, if the Secretary determines that such waiver of compliance is in the public interest and is consistent with railroad safety. Any such waiver may, based on a new petition, be extended for additional periods of up to two years, after notice and opportunity for comment. An explanation of any waiver granted under this section shall be published in the Federal Register.
(b) Report.— 
The Secretary of Transportation shall submit to Congress, no later than January 1, 1997, a report that
(1) explains and analyzes the effectiveness of all pilot projects established pursuant to a waiver granted under subsection (a);
(2) describes the status of all other waivers granted under subsection (a) and their related pilot projects, if any; and
(3) recommends appropriate legislative changes to this chapter.
(c) Definition.— 
For purposes of this section, the term directly affected covered service employees means covered service employees to whose hours of service the terms of the waiver petitioned for specifically apply.
