Gauge for standard gauge railways - Part 1: Rolling
stock gauge
1 Scope
This Part of GB 146 specifies the rolling stock gauge of 1 435 mm standard
gauge railways.
This Part applies to standard gauge rolling stock.

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.
