Reponses courtes
Quelle autorité ou quel corridor local compte pour ce type ?
Commencez par la lentille locale : homologation, licences et hubs — pas une checklist mondiale.
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.
Sur Tram-train / LRT, propulsion, structure, commande et sécurité partagent la même enveloppe d'exploitation.
Les jauges résument marge structurelle, maintenabilité et facteurs humains en score relatif.
Systèmes
Structure
Tram-train / LRT: Multi-section cars with low floors serve suburban corridors with mixed street and private right-of-way.
Propulsion
Tram-train / LRT: Pantographs feed inverters driving bogie-mounted motors; substations spaced for peak demand.
Énergie
Tram-train / LRT: Transponders request green extension at intersections; ABS-style block protection on ROW segments.
Commande
Tram-train / LRT: Raised platforms and ramp-free doors shorten dwell on commuter-style stops.
Interface
Tram-train / LRT: Corner posts and energy absorbers meet grade-crossing impact scenarios.
Sécurité
Tram-train / LRT: Validators and inspectors replace turnstiles; AVL supports headway management.
Indicateurs relatifs
Points chauds
Tram-train / LRT: Overhead splice failures
Tram-train / LRT: Bad splices arc in rain causing traction loss mid-sprint.
Tram-train / LRT: Curve rail lubrication
Tram-train / LRT: Dry flange contact squeals and wears gauge face prematurely.
Tram-train / LRT: Door obstacle detection
Tram-train / LRT: Nipped bags cause reopen cycles that break schedule.
Tram-train / LRT: Grade crossing predictors
Tram-train / LRT: False occupancy holds green for road traffic, delaying LRV.
Tram-train / LRT: Traction motor bearings
Tram-train / LRT: Whine precedes seizure on cars with high annual mileage.
Matériaux
Tram-train / LRT: Head-hardened rail
Tram-train / LRT: Extends life on mixed street and ballasted track.
Tram-train / LRT: Aluminum alloy carbody
Tram-train / LRT: Weight savings improve acceleration for suburban stop spacing.
Tram-train / LRT: Low-smoke cable compounds
Tram-train / LRT: Saloon wiring meets fire performance in enclosed sections.
Tram-train / LRT: CuAg contact wire
Tram-train / LRT: Conductivity reduces voltage drop on long feeders.
