2.2.5 MAINTAINING CWR TRACKA. It is a requirement of the FRA (49CFR 213.119) that each railroad managethe maintenance of CWR as to maintain thermal forces within safe limits.This Section 2, Rail, and Section 8, Prevention of Track Buckling, are apart of the SCRRA program to maintain CWR.B. In welded rail track, frequently inspect the joints and bolts. Replace bentand/or distorted bolts and checked or cracked joint bars. In order toprevent excessively wide openings at rail ends in extremely cold weather,replaced defective bolts one at a time. Maintain proper rail end, anchorpattern at joints in accordance with E.S. 1102. If a pull-apart occurs incontinuous welded rail or for any other reason it becomes necessary to sawin a short length of rail to restore service, use lengths between 19’6” and39’. The length of the inserted rail should be the same length as theremoved rail. Do not add rail, since this causes excessive stress and thus,kinks in hot weather. Field weld all rail cuts as soon as possible.C. Rail installation shall be in accordance with the Section 2.2.2.3 entitled“General Gang Operation”.D. At joints in welded rail where numerous contraction openings occur, makeadjustment of rail anchors when rail temperature is above the PRLT. Ifrail expander/puller cannot correct a contraction opening, saw in a sectionof jointed rail only as a last resort and only after notifying and consultingwith Manager, Track and Structures Maintenance.E. Do not lay continuous welded rail using expansion shims. Do not bump ordrive rail position in order to fill openings or in order to get rail intoposition to lay in track. (DO NOT ADD RAIL).F. When it is necessary to move continuous welded rail, do it by pulling;however, a rail expander may be used to secure proper openings forinsulated joint end-posts.G. Ballast shall be maintained per E.S. 1801, including both shoulders andcribs.2.2.6 DISTURBED TRACK2.2.6.1 SLOW ORDER CHART REGARDING DISTURBED TRACKA.
