铁路护栏网闻其名而知雅意就是用在铁路上的一种护栏网，渐渐被人们认可后才得此名号。它经常被用在铁路的两侧，起到封闭道路、铁路机车无障碍高速行驶作用的一种安全措施。它与铁路永远保持一定的距离，逢山开路遇水搭桥不离不弃，是铁路真正的保护伞。随着我国高速铁路、城际铁路的大力兴建，铁路护栏网的需求量也在日益增加，在护栏网中的地位也逐渐在升高。此外，铁路护栏网虽然有如此称呼，也并不代表它只应用在铁路上。
Railway fence is known by its name. Yayi is a kind of fence used on the railway. It won the name only after it is gradually recognized by people. It is often used on both sides of the railway. It is a safety measure to close the road and the barrier free high-speed running of railway locomotives. It always keeps a certain distance from the railway. It never gives up when crossing mountains and rivers. It is the real umbrella of the railway. With the vigorous construction of China's high-speed railway and intercity railway, the demand for railway guardrail is also increasing, and its position in the guardrail is also gradually increasing. In addition, although the railway guardrail is so called, it does not mean that it is only used on the railway.
