                    Subpart B_Use of Locomotive Horns
 
Sec.  222.25  How does this rule affect private highway-rail grade crossings?

    This rule does not require the routine sounding of locomotive horns 
at private highway-rail grade crossings. However, where State law 
requires the sounding of a locomotive horn at private highway-rail grade 
crossings, the locomotive horn shall be sounded in accordance with Sec.  
222.21 of this part. Where State law requires the sounding of a 
locomotive audible warning device other than the locomotive horn at 
private highway-rail grade crossings, that locomotive audible warning 
device shall be sounded in accordance with Sec. Sec.  222.21(b) and (d) 
of this part.
    (a) Private highway-rail grade crossings located within the 
boundaries of a quiet zone must be included in the quiet zone.
    (b)(1) Private highway-rail grade crossings that are located in New 
Quiet Zones or New Partial Quiet Zones and allow access to the public, 
or which provide access to active industrial or commercial sites, must 
be evaluated by a diagnostic team and equipped or treated in accordance 
with the recommendations of such diagnostic team.
    (2) The public authority shall provide the State agency responsible 
for grade crossing safety and all affected railroads an opportunity to 
participate in the diagnostic team review of private highway-rail grade 
crossings.
    (c)(1) At a minimum, each approach to every private highway-rail 
grade crossing within a New Quiet Zone or New Partial Quiet Zone shall 
be marked by a crossbuck and a ``STOP'' sign, which are compliant with 
MUTCD standards unless otherwise prescribed by State law, and shall be 
equipped with advance warning signs in compliance with Sec.  222.35(c) 
of this part.
    (2) At a minimum, each approach to every private highway-rail grade 
crossing within a Pre-Rule Quiet Zone or Pre-Rule Partial Quiet Zone 
shall, by June 24, 2008, be marked by a crossbuck and a ``STOP'' sign, 
which are compliant with MUTCD standards unless otherwise prescribed by 
State law, and shall be equipped with advance warning signs in 
compliance with Sec.  222.35(c) of this part.
