适用范围

The GA gauge may be implemented in the more or less long term on all railway lines. The GB qauge, which incorporates the GA gauge, is relevant for short or medium-term projects involving a maximum number of lines in order to develop a cohestve network over a relatively extensive area. The GC gauge, which incorporates the GA and GB gauges, is relevant for new lines and major rebuilding projects (for example: tunnels) on specially-targeted existing lines. For the GA and GB gauges, a transitional phase may be allowed during which the standard loads defined in Appendix see page 39 may be routed under the responsibility of the railway concerned, which should then ascertain, through appropriate calculations, that there exists maximum structure clearance. NB: Lines accepting such loads may be called GAO and GBO. The Gl3 gauge may be used on existing or future lines. It can be achieved at a lower cost than the gauges for lower parts defined in UIC Leaflet 505-4 since it primarily encounters occasional obstructions without consequence for larger obstacles such as platforms and structures. The GB1 and GB2 gauges shown in Appendix C - page 47 are options that involve the upgrading of specific lines when the GB gauge is not appropriate. The GB2 gauge incorporates the GB1 gauge, which in turn incorporates the GB gauge.
