Rolling stock gauge for standard gauge railways
1 Scope of application
This gauge applies to newly-made and transformed railway steam, electricity, diesel
locomotives, and all kinds of vehicles for 1435 mm standard gauge railways.
Note. “Newly-made” refers to the rolling stock designed and manufactured after
implementation of this Standard.
“Transformed” refers to the rolling stock that are designed and manufactured before
implementation of this Standard but are transformed according to this Standard.
2 Definitions
Rolling stock gauge is a limit cross-sectional contour perpendicular to the center line of
track. Regardless of empty or heavy vehicles, new vehicle with the maximum standard
tolerance, or old vehicles with the maximum standard tolerance and abrasion limit, when
the rolling stock parks on horizontal straight line, it shall not have lateral inclination and
offset. Except the pantograph arising from electric locomotives, all other parts shall be
accommodated in the limit-contour, and must not exceed the contour.
3 Usage
3.1 Rolling stock is designed based on gauge; gauge center line is the vertical line that
passes through the midpoint of two rails that are in straight line. Horizontal dimension of
rolling stock is counted from its centerline and expressed through its gauge’s half-width.
Vertical dimension is counted from rail surface.
3.2 For rolling stock’s design and manufacturing, both of the basic dimensions or tolerance
dimensions shall not exceed the limit cross-section contour line as prescribed by the gauge.
3.3 Rolling stock gauge-1A and rolling stock gauge-1B refer to the basic contour of rolling
stock gauge. The part that is 350 mm above rail surface is the upper gauge (rolling stock
gauge-1A). The part that is less than 350 mm above rail surface is the lower gauge (rolling
stock gauge-1B).
3.4 For the upper part of newly-made vehicles (vehicles that have not been operated since
production), the maximum dimension in the vertical plane, in unloaded state, may be
designed and manufactured according to the maximum dimension of rolling stock gauge-
1 A.
3.5 After spring subsidence and maximum abrasion in static-loaded state (or preparedness
state) has been taken into account, the design and manufacturing vertical dimension of the
lower part of newly-made vehicle must not be less than the vertical dimension prescribed
in rolling stock gauge-1B.
3.6 For the truck that passes through automation and mechanized hump locomotive
reducer, after spring subsidence and maximum abrasion in static loaded state has been
taken into account, the design and manufacturing vertical dimensions of its lower part must
not be less than the vertical dimensions prescribed for rolling stock gauge-2 of truck lower
gauge when vehicle reducer is at a braking or working position.
3.7 For shunting locomotive that passes through automation and mechanized hump
locomotive reducer, after spring subsidence and maximum abrasion in preparedness state
has been taken into account, the design and manufacturing vertical dimensions of its lower
part must not be less than the vertical dimensions prescribed for rolling stock gauge-3 of
shunting locomotive lower gauge when vehicle reducer is at a remission position.
3.8 For above clause 3.5 to clause 3.7, during determination on design and manufacturing
vertical dimensions of the lower part of newly-made vehicles, its spring vibration
subsidence (dynamic deflection) under dynamic load is not necessarily included.
4 Calculation method of maximum allowable width of
rolling stock
4.1 During determination of maximum allowable manufacturing width of rolling stock, it
shall not consider the lateral offset (limit value) when the travelling part of rolling stock with
maximum abrasion enters inti curve. For the rolling stock that participates in international
transport, or its limit value is required to be taken into account upon special requirements,
then it shall be specified in design specification.
4.2 Length of vehicle body is 13.22 m (26 m); bogie center distance is 9.35 m (18 m);
maximum allowable manufacturing width is 3400 mm. Vehicles with such dimensions are
defined as calculation vehicles (used for the calculation of vehicle width). When calculation
vehicle is on a calculation-curve of which the curve radius is 300 m, its maximum deviation
offset at the middle and end is 36 mm (135 mm for the middle; 147 mm for the end).
Note. The values listed outside the parentheses apply to the calculation of rolling stock for all-road
operation. The values listed inside the parentheses apply to the calculation of rolling stock that operates
on lines the comply with this construction gauge (the lines of which the curve-line is widened based on
this construction gauge).
4.3 For rolling stock design, when the length of vehicle body or bogie center distance does
