OAR 741-320-0070: Slope

(1) Except as provided in sections (2) and (3) of this rule, walkways shall not have a slope in excess of 1 to 8 in any direction. (2) Excess slope is permissible where the proximity of adjacent tracks so dictates so long as the slope between tracks is constant. When frequent switching occurs, or railroad employees inspect and repair cars, terracing may be required between adjacent tracks to provide a level surface for a walkway. (3) Excess slope is permissible at locations where a vehicle or pedestrian way intersects a standard walkway unless the Department, after investigation, upon its own motion or upon the petition of any aggrieved person determines that the safety of railroad employees requires the slope prescribed by section (1) of this rule.
