简短问答

这类交通工具要看哪些本地机构或走廊规则?

先看本地视角中的型式认定、营运许可与枢纽——不要假定一份全球清单。

Is this a buying guide?

No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.

Are the scores official?

No. The six scores are relative editorial 0–100 marks across the 48 types on this site.

Where do the photos come from?

Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.

Why metric units?

Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.

How is this different from a wiki article?

Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.

安全运行地铁需要按相同顺序追踪能量、信息与机械流。

CBTC、ERS等通用缩写保留,并在上下文中解释。

原理

就地铁而言,Station dwell dominance

就地铁而言,Passenger flow limits throughput more than train max speed on urban lines.

就地铁而言,Adhesion on leaf film

就地铁而言,Autumn contamination reduces acceleration and extends 制动 distance.

就地铁而言,Moving block spacing

就地铁而言,CBTC safe separation shrinks with accurate odometry and low latency radio.

就地铁而言,Third-rail gap

就地铁而言,Shoes must bridge gaps without losing propulsion on short third-rail sections.

就地铁而言,Piston ventilation

就地铁而言,Train motion pushes air through stations affecting platform comfort.

图解

就地铁而言,CBTC position loop

就地铁而言,Trains report position to zone controller.

就地铁而言,Station stop sequence

就地铁而言,Dwell gated by doors and PSDs.

运行步骤

01 就地铁而言,Line open & shunt

就地铁而言,Verify CBTC zone healthy and PSDs aligned before entering mainline.

02 就地铁而言,Board & close

就地铁而言,Monitor platform CCTV; close doors on interlock clearance.

03 就地铁而言,Notch acceleration

就地铁而言,Apply traction map to next speed cap respecting jerk limits.

04 就地铁而言,Cruise interstations

就地铁而言,Coast into stations where grades allow to save 制动 wear.

05 就地铁而言,Precision stop

就地铁而言,Berth within ±0.3 m for PSD and gap management.

06 就地铁而言,Turnback & sweep

就地铁而言,Cab swap or walk-through inspection at terminal loops.

硬性极限

就地铁而言,Headway & block limits

就地铁而言,CBTC still enforces minimum separation and station occupancy rules.

就地铁而言,Platform gap standards

就地铁而言,Horizontal and vertical gaps define accessible boarding aids.

就地铁而言,Tunnel evacuation routes

就地铁而言,Walkways and cross-passages govern emergency egress plans.
