分数是本图鉴内的相对0–100分。用于浏览，不是工程规格。
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.
货运列车的推进、结构、控制与安全在同一运行包线内耦合。先分清各系统名称与职责，便于故障模式与合规审查。
下方仪表为设计裕度、可维护性与人因的相对评分，用于同级平台比较。
系统
车体·转向架
就货运列车而言，Lead loco and mid-train/remote units synchronize traction via radio-linked throttle/制动 commands.
受流·牵引
就货运列车而言，Prime mover drives alternator; rectifier-inverter feeds axle-hung AC traction 电机s.
悬挂·轨面
就货运列车而言，制动 pipe pressure propagates service and emergency reductions to every car relay valve.
信号·ATP/CBTC
就货运列车而言，Positive train control enforces speed and authority limits on many North American lines.
旅客·疏散
就货运列车而言，Knuckle couplers and elastomer draft gear manage buff/draft forces in long consists.
空气动力
就货运列车而言，Tank cars, intermodal wells, and bulk hoppers follow AAR/FRA-style inspection and placarding.
相对量表
热点
就货运列车而言，Hot box detectors
就货运列车而言，Overheated bearings precede journal failures and derailments—wayside IR monitors trend rise.
