Zh-hans:Tag:railway=light_rail

一种高规格的电车系统。通常与其他交通系统分离，其定位介于有轨电车（railway=tram）与传统铁路（railway=rail）之间。

为轨道添加这个标签，以标注一条轻轨轨道。

定义

Definition according to Transportation Research Board: "A mode of urban transportation utilizing predominantly reserved but not necessarily grade-separated rights-of-way. Electrically propelled rail vehicles operate singly or in trains. LRT provides a wide range of passenger capabilities and performance characteristics at moderate costs.

There is no clear definition of light rail on OSM, the distinctions between conventional rail (rail), tram (tram) and subway (subway) are fuzzy. A light rail system should be mapped consistently, as long as there are no serious differences. Further below are some recommendations from railway mappers which should support the selection. In order to avoid conflict, please seek consensus on the forum or mailing lists before retagging.

The community of OpenRailwayMap has compiled a set of recommendations at their Aktiventreffen 2014 nr. 2.

railway=light_rail的特征：

• 既不是有轨电车，也不是火车
• 仅载客
• 连接城市中心地区与周边地区
• 通常与其他交通系统分离，平交路口有保护措施
• 建设比传统铁路简单，比有轨电车复杂
• 信号系统不太复杂
• 相比轻轨，地铁主要在地下运行，而且地上部分也极少有平交路口。
• connections to conventional rail are not a factor

Strong criteria for light rail against tram:

• Trams are driving on sight, while light rail has signals.
• Light rails are driving faster than trams because of own right of way and more complex signaling and protection.

Soft criteria for light rail against tram:

• own right of way
• high-floor
• underground railway
• elevated railway
• workrules like conventional rail
• drives overland to the surroundings
• constructed stops rather than simple bus-like stops at the road level.
• stops are separating the passengers from the tracks
• presence of so-called third rails

标签

• electrified=contact_line/rail 电气化铁路：接触网供电/普通铁路
• gauge=* 轨距（mm）
• frequency=* 交流电频率（0为直流）
• voltage=* 电压（V）
• maxspeed=* 最高速度
• service=yard/siding/crossover 类型：站场/侧线/渡线
• workrules=*

运营线路

欲标注铁路运营线路，请使用route relation

例子

• 

  港区轻轨

• 

  斯图加特轻轨

• 

  吉隆坡格拉那再也轻快铁

就运行在柏林与汉堡之间的“S-Bahn”（由Deutsche Bahn运营）城际运输系统究竟是轻轨还是火车，目前尚无定论。

不要在城市交通外的轨道交通系统中使用这个标签。

railway=narrow_gauge 适用于使用窄轨的国家或州
