Structure gauge for standard gauge railways
1 Scope
This Gauge is applicable to 1435 mm standard gauge railways.
2 Definition
Structure gauge is the limit cross-sectional contour that is perpendicular to the
center line. Within this contour, in addition to railway vehicle and the device
(vehicle reducer, tablet exchanger, contact wire, etc.) that interact with the
railway vehicle, other equipment or building must not invade.
3 Instructions
3.1 Whether it uses new rail or old rail (including long-term replacement of thick
heavy rail track bed), the size of structure gauge, counting from the rail surface,
shall comply with the provisions.
3.2 The size of structure gauge figure is specified for horizontal straight-line.
3.3 The expanded distance of center distance between adjacent lines in the
curved part as well as the one from the line’s midline to the building shall be
calculated according to the specified equation.
3.4 In the curved part, due to the ultra-height of outer rail, the vertical height of
structure gauge shall be counted from the straight-line that is formed by the
highest points of the inner rail and the outer rail. The horizontal size shall be
counted from the widened line center.
3.5 The distance of adjacent line’s centerline of railway station and interval AND
the size of other secondary gauge are specified in technical design
specifications or standards of Ministry of Railways.
4 Basic size
4.1 Basic structure gauge
4.1.1 Structure gauge-1
4.1.1.1.2 Technical reformation of business railway.
a. During the construction of complex line, at least one line must comply with
structure gauge-1.
b. Railway that is designated for technical reformation by Ministry of Railways.
4.1.1.1.3 Loading gauge is 4450×5300 freight train. Cargo loading size can
refer to Appendix B. When each level of out-of-gauge freight train is running on
the single line or complex line, it shall be handled according to the transport
method for out-of-gauge cargo.
4.1.1.2 Widening method for structure gauge on curve.
Inward curve widening, mm,
Outward curve widening, mm,
Total widening of inward curve and outward curves, mm,
Where,
Ri - curve radius, m;
H – height counting from rail surface, mm;
h - ultra-height of outer rail, mm.
ଵହ଴଴·h value can be obtained by using inward rail top as axis, rotating the
relevant gauge at θ angle.
Reference table for the minimum size of catenary to rail surface at the
maximum laxity
Sequence ① Catenary installation location
Loading height of freight
train mm
4800 ③ 5300
2 Interval 5500 5750
3 Over bridge in-station or near-station, under overpass 5500 5700
4 Within bridge structure gauge and tunnel structure gauge 5200 5700
Note.
① Catenary voltage is 25~35 KV.
② The maximum hanging height from rail surface of catenary is 6500 mm. For operators
without shunting in small station, the hanging height of intracontinental catenary is same
with the one of interval’s.
③ The basic loading height of freight train when this railway gauge is not applicable, for
Additional information.
This Standard was proposed by Ministry of Railways of PRC and shall be under
the jurisdiction of Standard Metrological Institute of Ministry of Railways.
This Standard was drafted by Standard Metrological Institute of Ministry of
Railways.
Drafter of this Standard. Yu Jianjun.
