This Part applies to standard gauge rolling stock. 2 Normative references The following documents are indispensable for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest edition (including all amendments) applies to this document. GB 146.2-2020, Gauge for standard gauge railways - Part 2: Structure gauge 3 Terms and definitions The following terms and definitions are applicable to this document. 3.1 Rolling stock gauge The limit cross-sectional contour that is perpendicular to the center line of the track and restricts the outer dimensions of the rolling stock. 3.2 Basic car The nominal car, with a given car body length and bogie center distance, that is used when determining the maximum width reduction of a rolling stock. 4 General 4.1 The center line of the rolling stock gauge is the vertical line that passes through the center of the straight line. The horizontal dimension of the rolling stock is calculated from its centerline and expressed in half-width of the gauge. The vertical dimension is calculated from the rail surface. 4.2 The rolling stock gauge is divided into upper gauge and lower gauge. The part above the height of 350 mm from the rail surface is the upper gauge; the vehicle gauge-1A is the basic contour of the upper gauge of the railway rolling stock, as shown in Figure 1. The part of a height of 350 mm and below from the rail surface is the lower gauge; the vehicle gauge-1B and vehicle gauge-1C are the basic contours of the lower gauge of the railway rolling stock. The vehicle gauge-1B is shown in Figure 2; the vehicle gauge-1C is shown in Figure 3. 4.3 The rolling stock, whether it is empty or loaded, whether it is a new vehicle with the largest standard tolerance, or an old vehicle with the largest standard tolerance and wear limit, is parked on a horizontal straight line, without lateral tilt and offset; the part that needs to be protruded only when parking shall be retracted; except for the raised pantograph, all other parts shall be contained within the rolling stock gauge. 4.4 When the rolling stock is designed and manufactured, neither the basic size nor the tolerance size shall exceed the limit cross-sectional contour line that is specified by the gauge. 5 Vertical contour dimensions of rolling stock 5.1 The maximum dimension in the vertical plane of the upper part of a newly- built (not used after production) rolling stock under light condition can be designed and manufactured according to the maximum dimension of the vehicle gauge-1A. 5.2 The designed and manufactured vertical dimensions of the lower part of the newly-built rolling stock, after taking into account the spring static deflection and maximum wear under static load (or under heavy condition), shall not be less than the vertical dimension that is specified by the vehicle gauge-1B or the vehicle gauge-1C. 5.3 For trucks that pass automated and mechanized hump vehicle reducers, the designed and manufactured vertical dimension of the lower part, after taking into account the spring static deflection and maximum wear under static load, shall not be less than the vertical dimension the is specified by the vehicle gauge-2 of the lower gauge of the truck when the vehicle reducer is in the braking or working position. 5.4 For shunting engines that pass automated and mechanized hump vehicle reducers, the designed and manufactured vertical dimension of the lower part, after taking into account the spring static deflection and maximum wear under heavy condition, shall not be less than the vertical dimension that is specified by the vehicle gauge-3 of the lower gauge of the shunting engine when the vehicle reducer is in the relief position. ......
