§ 33.81. Track alignment.

 (a)  All track shall be constructed with curvature so limited or with tangent track so placed between reverse curvature that lateral displacement of the car couplers with the center axis of any car does not exceed 13°. Crossovers between tracks and turnouts shall be similarly constructed. Tracks designed to accommodate two coupled cars, each with trucks spaced 70 feet between truck centers and with couplers 29 inches from the center of the pivot to the pulling face of the knuckle, shall be deemed in compliance with this regulation.

 (b)  If, in any particular case, exemption from any of the requirements in this section is deemed necessary by the carrier concerned, the Commission may grant application of such carrier for such exemption, provided the application is accompanied by a full statement of existing conditions and the reason why such exemption is sought. Any exemption so granted shall be limited to the particular case covered by application.

 (c)  Subsections (a) and (b) do not apply to repairs, renewals, or maintenance of track, but nothing in this section shall be construed as restricting the rights of carriers to decrease track curvature.

   The provisions of this §  33.81 were formerly designated Rule 19 by the Commission.
