34、tance between those rails (See Fig. 1).5.7.2 ApplicationIf used, gauge rods shall be installed at right angles to the rail with the jaws firmly gripping the base of therail.5.8 RailRail shall meet the requirements of the Designer/Engineer.5.8.1 Short RailShort rails and joint gap fillers shall provi

35、de wheel guidance to mitigate a derailment at the maximum speedstipulated by the Operator.5.9 Track GeometryOne rail shall be designated as the line rail. The alignment of the track is established by this rail. Eitherrail may be used as the line rail on tangent track so long as the same rail is used

36、 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 rail of the curve.5.9.2 The following figures define track geometry for all gauges that shall be used by the Des

37、igner/Engineer to establish therequirements for the track. These figures will be referenced in subsequent sections.5.9.3 GaugeGauge is the distance between a point one-half the depth of the rail head below the top surface of the two railsmeasured at right angles to the rail or, for standard gauge, 5

38、8 in. (15.9 mm) below the railhead as shown in Fig. 9. The minimumand maximum gauges shall be determined using Fig. 3 and Fig. 4 respectively.5.9.3.1 Gauge less than standard or if the rails are cantedGauge is the minimum distance between the rail heads, measuredat right angles to the rails at the r

39、ail head. Canted rail is the inclination of both rails towards the center line of the track, typicallyby the use of inclined tie plates, usually at an incline of 1 in 20. See Fig. 10.5.9.3.2 In curves the gauge, as defined in 5.9.3, shall be adjusted for the degree of curvature, the tread width and

Between the tangent and curvedtrack is the transition track. Super elevati

42、on in the transition varies from level at the tangent to full super elevation at the curve.5.11 Super ElevationSuper elevation is the banking of track by raising of the outside rail or lowering of the inside rail in acurve. The amount of super elevation is a function of the degree of curvature, prop

43、osed speed of the train and the location of thecenter of gravity of the train vehicles. The super elevation shall be designed so that the combined force vectors from the weightof the train and the centripetal forces due to the trains speed in a curve shall act as a combined force vector intersecting

44、 the tiesurface between the rails (stable) versus outside the rails (unstable). The design shall use a train speed from zero to the maximumspeed, including over speed conditions, to ensure overturning stability is provided.5.12 Turnouts:FIG. 1 Gauge Rods (installed on rails, ties and tie plates not
