32、eaded at its ends withfeatures at its end that attach to opposing rails for the purposeof maintaining the gauge distance between those rails (See Fig.1).5.7.2 ApplicationIf used, gauge rods shall be installed atright angles to the rail with the jaws firmly gripping the base ofthe rail.5.8 RailRail s

33、hall meet the requirements of the Designer/Engineer.5.8.1 Short RailShort rails and joint gap fillers shallprovide wheel guidance to mitigate a derailment at the maxi-mum speed stipulated by the Operator.5.9 Track GeometryOne rail shall be designated as theline rail. The alignment of the track is es

34、tablished by this rail.Either rail may be used as the line rail on tangent track so longas the same rail is used for the entire length of the tangent.5.9.1 In curves, the inside rail is designated as the grade rail.The grade rail is the reference from which super-elevation isapplied to the outside r

35、ail of the curve.5.9.2 The following figures define track geometry for allgauges that shall be used by the Designer/Engineer to establishthe requirements for the track. These figures will be referencedin subsequent sections.5.9.3 GaugeGauge is the distance between a point one-half the depth of the r

36、ail head below the top surface of the tworails measured at right angles to the rail or, for standard gauge,58 in. (15.9 mm) below the railhead as shown in Fig. 9. Theminimum and maximum gauges shall be determined using Fig.3 and Fig. 4 respectively.5.9.3.1 Gauge less than standard or if the rails ar

37、e cantedGauge is the minimum distance between the rail heads,measured at right angles to the rails at the rail head. Canted railis the inclination of both rails towards the center line of thetrack, typically by the use of inclined tie plates, usually at anincline of 1 in 20. See Fig. 10.5.9.3.2 In c

38、urves the gauge, as defined in 5.9.3, shall beadjusted for the degree of curvature, the tread width and wheelbase of the rolling stock but shall not exceed the values of Fig.4. (See X5.9.3.2 for definition of degree of curvature.)5.10 Cross Level:5.10.1 DefinitionCross level is the difference in ele

39、vationbetween the top surfaces of the two rails measured at rightangles to the track, as shown in Fig. 115.10.2 Designated Cross LevelOn tangent track, the crosslevel shall be zero 6 tolerance specified by the Designer/Engineer. On curved track, the designated cross level is equalto the designated s

40、uper elevation (see 5.11). Between thetangent and curved track is the transition track. Super elevationin the transition varies from level at the tangent to full superelevation at the curve.5.11 Super ElevationSuper elevation is the banking oftrack by raising of the outside rail or lowering of the i

41、nside railin a curve. The amount of super elevation is a function of thedegree of curvature, proposed speed of the train and thelocation of the center of gravity of the train vehicles. The superelevation shall be designed so that the combined force vectorsfrom the weight of the train and the centrip

42、etal forces due to thetrains speed in a curve shall act as a combined force vectorintersecting the tie surface between the rails (stable) versusoutside the rails (unstable). The design shall use a train speedfrom zero to the maximum speed, including over speedconditions, to ensure overturning stabil

43、ity is provided.5.12 Turnouts:5.12.1 TurnoutThe section of rail from the tip of switchpoints (point of switch) to the heel of the frog shall beconsidered the turnout.5.12.2 General requirements for turnouts.5.12.3 MaterialsAll materials used within the limits of aturnout shall be specified by an Des

46、 fastenedand provide for proper alignment at the approach track endwhen the moveable approach track is thrown in either direc-tion. The rail ends of both the approach track and the stock andclosure rails shall bear on a common tie or contiguous bearingplate, or both. Means shall be provided to preve

47、nt misalign-ment between the approach and turnout tracks in all operatingpositions to the extent that a derailment potential is created atthe speed allowed for the turnout.5.12.6.2 Means shall be provided to prevent longitudinalmovement of the approach, stock, and closure rails to theextent that the

48、y no longer bear on a common tie or bearingplate.5.12.6.3 End gap between approach rails and closure/stockrails shall be sufficient to allow throwing the switch withoutbinding.FIG. 1 Gauge Rods (installed on rails, ties and tie plates not shown)F2960 1435.12.6.4 End gap between approach rails and cl
