Purpose and description
Enable an agent to recognise TGV high-speed passenger rolling stock, assess its configuration and readiness, and identify the evidence required for a proposed operation.
TGV (Train à grande vitesse) denotes the French family of high-speed passenger trainsets developed for SNCF, principally using electric traction and articulated passenger coaches, and also names the associated high-speed rail service.
It can be Identify the applicable TGV generation and flag uncertain or contradictory identification.; Compare a documented configuration with a proposed route and platform sequence.; Assess a proposed coupled formation against documented compatibility and operating limits.; Determine which inspections, restrictions and release evidence must be checked before service.; Locate configuration-specific procedures for degraded operation, evacuation and recovery..
Distinguishing features
Require documented TGV family membership; high speed, French operation or a TGV-branded journey alone does not establish the rolling-stock identity.
Distinguish the physical train family from a particular generation, manufacturer designation, commercial service and numbered trainset.
Use documented formation, power-vehicle arrangement and bogie layout to test family and variant identification rather than relying on livery.
Establish capabilities from the identified configuration; do not transfer voltage, signalling, seating or speed specifications between TGV generations.
Scope
+ Evidence identifying rolling stock as belonging to the TGV family
+ Trainset formation, vehicle arrangement and passenger accommodation
+ Electric traction, current collection and braking capabilities
+ Compatibility with routes, electrification, signalling and platforms
+ Operational readiness, maintenance restrictions and emergency provisions
- TGV commercial branding, fares, reservations and timetables
- High-speed railway infrastructure as an independently managed asset
- Other high-speed train families merely operating on the same routes
- Railway operators, infrastructure managers and their organisational models
- A complete asset record for an individual trainset or a catalogue of every TGV variant
Characteristics
- Family and generation identification
- Documented TGV family designation, generation or series; unresolved Determines which technical evidence applies and prevents confusion with service branding.
- Trainset formation
- Vehicle count, vehicle roles, deck arrangement and bogie arrangement Affects capacity, inspection, platform fit and recovery arrangements.
- Compatible electrical supplies
- Documented combinations of voltage in kV, AC or DC, and frequency in Hz where applicable Constrains routes and the procedures needed at electrical-system transitions.
- Installed train protection
- System names, versions and enabled configurations A train cannot be assumed compatible with a route merely because its electrical supply matches.
- Authorised maximum speed
- km/h, qualified by train configuration, route and operating conditions Separates permitted operation from design capability and record-setting demonstrations.
- Formation length
- m, for a single trainset and any proposed coupled formation Supports platform, siding and depot compatibility checks.
- Passenger capacity
- Passenger places by seating configuration and designated accessible spaces Capacity depends on the actual interior layout rather than the family name.
- Coupling compatibility
- Compatible trainset configurations and permitted operational or rescue coupling modes Mechanical connection does not by itself establish control, braking or passenger-service compatibility.
- Service readiness
- Released for service; restricted; awaiting inspection; withdrawn; unknown Connects defects and maintenance evidence to permissible operation.
- Applicable authorisation
- Configuration-specific authorisation and route-compatibility evidence with issuing authority and validity Identifies the evidence governing where and under what conditions the train may operate.

TGV identity and boundary Establishes which physical rolling-stock family and configuration the entry represents.
TGV can identify a train family or a commercial service, and those senses support different decisions.
Family membership
Tests the evidence connecting a train designation to the TGV physical family.
Documented TGV membership
Record family membership with an attributable designation rather than inferring it from speed or branding.
- Which manufacturer, operator or technical authority identifies this rolling-stock designation as TGV? provenance
- Does this designation refer to physical rolling stock, a commercial service or both? boundary
Generation and configuration
Locates generation-specific capabilities beneath the shared family identity.
Configuration applicability
Associate capability statements with the series, modifications and formation to which they apply.
- Which generation, series and modification state must be known before applying technical specifications? definition
- Which apparent TGV relatives require links to neighbouring rolling-stock models rather than inclusion here? boundary
Formation and passenger fit Describes how the train's vehicle arrangement affects accommodation and physical compatibility.
TGV configurations must be distinguished by formation and deck arrangement before capacity or platform suitability can be judged.
Vehicle and bogie arrangement
Captures the arrangement of powered vehicles, passenger vehicles and their running gear.
Formation geometry
Record the documented formation and geometry without assuming every TGV generation has an identical arrangement.
- What are the vehicle roles, deck arrangement and shared or independent bogie positions for this configuration? definition
- What are the formation length, loading-gauge envelope and relevant axle loads, with units and configuration qualifiers? measurement
Boarding and accommodation
Connects the passenger layout to boarding, accessibility and evacuation constraints.
Passenger layout fit
Assess passenger places and access against the actual interior and door configuration.
- How many passenger places and designated accessible spaces does this interior configuration provide? measurement
- Which platform heights, boarding aids and internal level changes affect access to those spaces? action
Traction, braking and control Identifies the electrical, braking and control capabilities needed for a proposed journey.
TGV family identity does not establish compatibility with every supply system, signalling installation or operating speed.
Electrical operation
Relates current collection and traction configuration to the route's electrical systems.
Supply and transition compatibility
Record supported supplies and the documented operating requirements for transitions between them.
- Which supply voltages, frequencies and pantograph configurations are supported by this TGV variant? measurement
- Which procedures and restrictions govern neutral sections or changes of electrical system? action
Speed protection and stopping
Connects signalling compatibility and available braking to permitted operation.
Protected operating envelope
Evaluate speed permission using the installed protection systems, available brakes and configuration-specific restrictions.
- Which train-protection systems and versions are installed, enabled and accepted for the proposed route? provenance
- What speed and operating restrictions follow from the available braking modes or an isolated brake subsystem? action
Route and formation permission Determines whether a particular TGV configuration and formation may undertake a proposed movement.
Technical capability, infrastructure fit and authorisation must all apply to the same configuration.
Route acceptance
Links the train configuration to authoritative route and operating constraints.
Authorised route fit
Keep authorisation evidence distinct from an inferred match of technical specifications.
- Which authorisations, governing standards and issuing bodies apply to this configuration and intended area of use? provenance
- Which route-specific limits remain after checking gauge, axle load, electrification, signalling and platform fit? boundary
Coupled operation
Distinguishes passenger-service multiple working from a connection made solely for rescue.
Coupling mode permission
Record compatible partners and coupling modes, including control and braking limitations.
- Which TGV series or configurations are documented as compatible for multiple working? provenance
- What checks and restrictions distinguish a passenger-service coupled formation from rescue towing? action
Readiness and recovery Connects inspection, defects and emergency provisions to service decisions.
A correctly identified and route-compatible TGV may still be unavailable because of maintenance status or failed safety functions.
Maintenance and release
Identifies configuration-specific evidence needed to establish service readiness.
Defect-dependent release
Relate inspection results and isolated equipment to documented release criteria.
- Which inspections and limits apply to the running gear, pantographs, brakes and passenger-door interlocks on this configuration? provenance
- Which recorded defects, overdue tasks or consumable conditions prohibit service or require restrictions? action
Degraded operation and evacuation
Locates the approved response to immobilisation, loss of power and passenger emergencies.
Configuration-specific recovery
Assess recovery using the train's formation, emergency equipment and documented procedures.
- Which approved procedures govern isolation, rescue coupling and movement of an immobilised trainset? action
- How do deck arrangement, emergency exits and loss of auxiliary power affect evacuation provisions? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
