  Subpart D--On-Track Roadway Maintenance Machines and Hi-Rail Vehicles
 
Sec. 214.511  Required audible warning devices for new on-track roadway maintenance machines.

    Each new on-track roadway maintenance machine shall be equipped 
with:
    (a) A horn or other audible warning device that produces a sound 
loud enough to be heard by roadway workers and other machine operators 
within the immediate work area. The triggering mechanism for the device 
shall be clearly identifiable and within easy reach of the machine 
operator; and
    (b) An automatic change-of-direction alarm which provides an audible 
signal that is at least three seconds long and is distinguishable from 
the surrounding noise. Change of direction alarms may be interrupted by 
the machine operator when operating the machine in the work mode if the 
function of the machine would result in a constant, or almost constant, 
sounding of the device. In any action brought by FRA to enforce the 
change-of-direction alarm requirement, the employer shall have the 
burden of proving that use of the change-of-direction alarm in a 
particular work function would cause a constant, or almost constant, 
sounding of the device.
