Walkway Standard No. 4: Derails


Walkway Standard No. 4 shall be a walkway constructed and maintained to conform, in width and elevation, to OAR 741-320-0100 (Walkway Standard No. 3: Switches) (Standard No. 3). As measured from the derail mechanism, the walkway shall extend for 20 feet toward the switch and 10 feet away from the switch. At derails operated by a switch stand, an additional 3 feet of walkway width shall extend for a minimum distance of 4 feet in each direction from the switchstand, and only on the switchstand side of the track. This additional 3 feet of width shall be gradually tapered back to the 6 feet minimum width in a distance of not less than 20 feet in the direction toward the switch and not less than 10 feet in the direction away from the switch.


Derails located within 200 feet of a switch throwing mechanism shall have a continuous Standard No. 3 walkway between the two on the same side of the track as the derail or derail switch stand.


See Figure 320-4 for a diagram of the minimum measurements for Walkway Standard No. 4.
