Locomotive Conspicuity; Minimum Standards for Auxiliary External Lights

Interim rule with request for comments.

This interim rule (referred to as ``IR-2'') amends FRA's interim rule (referred to as ``IR-1'') published on February 3, 1993, by relaxing the standards IR-1 contained concerning auxiliary external lights on locomotives. IR-2 contains detailed and specific performance standards regarding color, intensity, operation, mounting location and flash rate for ditch lights, crossing lights, strobe lights and oscillating lights. This action is intended to increase the visibility of locomotives to motorists and thereby reduce the incidence of accidental collisions between motor vehicles and locomotives at highway-rail grade crossings.
