Diesel-hydraulic locomotive manufacture

1. Scope and Applicability

This candidate PCR governs new complete diesel-hydraulic rail locomotives with diesel engine power transferred through hydrodynamic torque-converter transmission and mechanical final drive to wheelsets. It is narrower than CPC49519. Exclude tenders, steam, electric, diesel-electric and battery/hybrid traction locomotives, pure hydrostatic traction, railcars/multiple units, incomplete frames or engines sold separately, reconstruction/repair and transport/maintenance services. One accepted finished unit is one complete locomotive.

Manufacturing foreground starts at actual received stock and supplier modules and ends at documented complete-vehicle acceptance/delivery. Producer fabrication, assembly, conditional coating, drivetrain/outfitting, attributable construction tests and actual protection are included once; operation and lifetime hauling fuel are excluded. Public manufacturer examples support architecture and possible process stages, not a universal BOM, test cycle or mass. Scientific review is pending.

Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	producer/model and serial; drawing/BOM revision; gauge, axle arrangement, wheelsets/bogies, axle gears and installed ballast; diesel engine number/type/serial and supplier inclusions; hydrodynamic converter/transmission, cardan shafts, final drive, cooling, brakes and controls; cab/coupler/safety/aftertreatment configuration and actual coatings; net delivery fluid state; accepted positive measured M kg and cp_mass, calibrated weighing evidence and signed corrections; exclude fuel, operational sand, persons, temporary test loads, packaging and loose spares; actual factory/site/period and gate, supplier completion and test coverage

Record actual same-configuration net accepted mass: a catalogue total weight, axle-load rating, installed power or nominal fill capacity is not M. [Source: gmeinder-model]

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass.
mass_record_origin	cp_mass	Mass	kg	Require actual calibrated rail weighing or wheel-load measurements, original serial/configuration-linked instrument and calibration records, all wheels/supports and tare, measured fuel/sand/temporary-load corrections, installed ballast and retained service fluids. Sum independently measured wheel loads only with all supports covered and declared static condition, simultaneous/sequential procedure, calibration and repeatability checks. Signed mass reconciliation establishes net delivery scope. Never infer M from catalogue or an invented per-unit weight.
engine_count	engine	Number of items	Item(s)	Retain public item-count reference for complete supplied diesel engines. Collect accepted installed engine serial count per locomotive; normalize q_item counts by the same measured M. Record independent actual engine/module mass for configuration and total mass reconciliation, not to rewrite the engine flow property as Mass.
energy_conversion	electricity	Net calorific value	MJ	Meter attributable intake electricity; actual kWh converts with verified unit identity3.6 MJ/kWh. Record voltage/geography and provider route; nameplate kW is not energy.
fluid_scope	first fill and trial fuel	Mass	kg	Measure actual net fills and supplier-prefilled contents once, retained versus consumed/discharged. For a volume record require measured same-composition/state density and temperature; nominal tank/oil capacity and generic calorific value are not conversion evidence.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Received specified stock, fabricated frame/bogies and engine/transmission/outfitting modules with actual supplier inclusions
starting_condition_role	Foreground receipt-to-accepted-complete-locomotive manufacture
product_classification_scope	Complete hydrodynamic diesel-hydraulic locomotive, not tenders or diesel-electric/hydrostatic traction
recursive_input_rule	Do not recursively manufacture a complete locomotive as its own input. A bought complete intermediate/module replaces included operations and constituents once.
upstream_dataset_requirement	Link actual provider/grade/module completeness, property, route, period/geography; disclose missing upstream and outsourcing
disclosure	producer/model and serial; drawing/BOM revision; gauge, axle arrangement, wheelsets/bogies, axle gears and installed ballast; diesel engine number/type/serial and supplier inclusions; hydrodynamic converter/transmission, cardan shafts, final drive, cooling, brakes and controls; cab/coupler/safety/aftertreatment configuration and actual coatings; net delivery fluid state; accepted positive measured M kg and cp_mass, calibrated weighing evidence and signed corrections; exclude fuel, operational sand, persons, temporary test loads, packaging and loose spares; actual factory/site/period and gate, supplier completion and test coverage

rule_id	applies_to	rule	source_ids
boundary_foreground	all stages	Include actual producer operations and attributable rework/test and first-fill resources once through the declared gate. Supplier-completed fabrication/assembly is represented by its bought intermediate, not duplicated local resources. Report missing stages and conditional absences explicitly.	zagro-production
boundary_operations	trials and downstream	Construction-acceptance testing belongs to manufacture only for demonstrated represented units and actual protocol. Exclude revenue shunting/hauling, maintenance, spare replacement, operation fuel/sand, infrastructure and lifetime transport service. A supplier development endurance run is not automatically a per-locomotive factory burden.	voith-gears
boundary_upstream	bought inputs	Expose each actual received exchange and supplier manufacturing scope; missing upstream datasets prevent a complete cradle-to-gate claim. Declare outsourcing and actual transport/service links separately with physical measured basis; no unspecified service collection is an inventory flow.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
frame	Frame and cab fabrication	conditional	Actual stock fabrication occurs inside the reporting manufacturer boundary.	foreground	one accepted configured locomotive, normalized with M
running_gear	Bogie, wheelset and brake integration	required	Every complete declared locomotive configuration.	foreground	one accepted configured locomotive, normalized with M
powertrain	Diesel hydrodynamic drivetrain installation	required	Complete diesel engine and hydrodynamic transmission with mechanical axle drive.	foreground	one accepted configured locomotive, normalized with M
coating	Conditional surface preparation and painting	conditional	Actual preparation/painting occurs in the manufacturer foreground.	foreground	one accepted configured locomotive, normalized with M
outfit	Controls and auxiliary outfitting	required	Each complete configuration released by the producer.	foreground	one accepted configured locomotive, normalized with M
acceptance	Construction commissioning and locomotive acceptance	required	Each accepted complete locomotive and any attributable sampled factory tests.	foreground	one accepted configured locomotive, normalized with M
packing	Conditional delivery protection	conditional	Actual removable protection supplied at the declared gate.	foreground	one accepted configured locomotive, normalized with M

Frame fabrication feeds running-gear and drivetrain integration with conditional coating, controls/outfitting and construction acceptance, then conditional protection. Actual station sequence and supplier modules govern attribution. Required assembly stages do not make every listed exchange mandatory: each card requires actual matching composition/state and independent supplier scope. Add every omitted actual component/formulation/species separately before completing a quantitative dataset. Unknown is a gap.

Process: Frame and cab fabrication (frame)

Cut/form/machine specified steel stock, assemble and weld frame/cab and inspect actual joints. Record drawings, actual plate grade, filler/shielding composition, rework and machining fluid. A bought finished frame/cab bypasses its included fabrication; casting, forging or heat treatment are not presumed in-house.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_orders	shared manufacturing resources	Separate locomotive orders/configurations and subdivide directly metered stages first. Assign actual stock/module receipts, job/test resources and rework by measured records. An inseparable shared resource uses demonstrated causal operation time/load or layer-area driver: share = order driver / sum of drivers for all covered orders. Retain evidence, period, all orders and denominator. Nominal weight, horsepower or equal-unit shares are not automatically causal.	ghg-allocation
allocation_recovery	scrap and internal transfers	Internal stock/fluid/fuel reuse is a transfer, not repeated fresh input or a credit. Exported scrap/waste retains actual mass and recipient; no assumed avoided-steel/oil benefit. Separate genuine co-products; any residual allocation requires justified consistent driver and documented review. Reconcile rejected/reworked units and work-in-progress to accepted period output.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_mass	all inventory rows	q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow.	q_item; M; cp_mass	q_ref

Collect each net exchange for the actual order, subtract recorded returns and stock change, apply any justified shared allocation and divide by accepted locomotive count to obtain q_item. Normalize to the same measured complete configuration M. Mass rows remain kg/kg, engine count Item(s)/kg and electricity MJ/kg. Directly counted supplied complete engines retain Count; independent engine weight only reconciles net configuration. Compatible serial units with observed mass variation may use attributable totals divided by summed measured accepted masses, retaining every serial record. Separate incompatible gauge/drive, bogie, ballast, coating and acceptance configurations. Unknown inputs or untested extrapolations require review.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_mass	cp_mass	Acceptance records must implement mass_record_origin; original calibrated physical wheel/rail measurements, serial and all mass-state corrections are required. Missing actual method or unexplained catalogue/axle rating blocks a completed quantitative dataset.	original weight report/calibration/correction balance
quality_bom	all stages	Reconcile frame/cab, all bogies/wheelsets, engine/transmission/cardans/axle gears, ballast, brakes/control and actual auxiliary/aftertreatment/fluid masses to accepted scope. Retain supplier inclusions and add each omitted actual BOM constituent without double counting.	drawings/BOM/supplier inclusions/measurements
quality_trial	acceptance	Retain actual test protocol/track/stand, load/duration, sampled-unit coverage and net fuel/fluid returns. Exhaust species require integrated calibrated measurements with detection limits and actual medium; unsplit NOx is not NO/NO2 and biological fraction is not fossil CO2.	test, fuel and species originals
quality_coverage	dataset	Declare actual site/period, configuration/supplier scope, conditional absence, outsourcing, allocation, identity/quantity gaps, uncertainty, empirical QA limits and missing upstream. Establish actual QA ranges from calibrated records or verified compatible evidence, never invented yields/weights/lifetimes. This PCR check verifies declared relationships, not actual records or scientific approval.	coverage and original-record register

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	reference	Require complete hydrodynamic diesel-hydraulic locomotive and positive measured net M implementing cp_mass and mass_record_origin. Match gauge/axles/bogies, drivetrain, ballast and fluid state; reject catalogue total, rated axle load or nominal fill as weight evidence. Reference output name must match the reference product exactly.
validate_identity	all rows	Verify atomic substance/component, public state100 name, actual reference property/unit group, route/scope and completeness. Preserve engine Count; electricity Energy is not Mass. Hydrodynamic transmission is not hydrostatic hydraulic unit. Unsupported identity stays blank with exact row registration.
validate_boundary	supplier and test scope	Count complete supplier modules and prefills once; do not duplicate engine/bogie constituents. Verify represented acceptance-test coverage and consumed versus retained fuel/sand. Separate manufacturing trials from revenue hauling and supplier development tests. Missing actual quantity or underlying weighing method remains review.
validate_species	elementary rows	Use only demonstrated attributable construction-trial releases to exact medium/submedium. CO2 fossil, NO and NO2 identities here are immediate air-unspecified; not biogenic CO2, N2O, nitrogen/nitrite, soil/water or long-term release. Captured waste is not emitted species.
validate_profile	claimed completeness	Link actual upstream and supplier/period/geography before a cradle-to-gate claim; record original acceptance documentation and applicable actual regime for any certificate claim. Generic manufacturer capability does not approve this locomotive methodology or its specific vehicle.

10. Published Dataset Profile

Field	Value
dataset_role	Configured complete diesel-hydraulic locomotive foreground manufacture dataset
downstream_use	secondary_dataset; background_dataset after qualified review and linked upstream scope
allowed_use	Manufacturing supply-chain models matching gauge, hydrodynamic drive, bogies/ballast/outfitting/fluid state, accepted net-M scope and gate/site/period
excluded_use	Train/shunting transport service, lifetime hauling fuel, equal-mass traction equivalence, other traction architectures or unsupported complete cradle-to-gate claims
required_metadata	producer/model and serial; drawing/BOM revision; gauge, axle arrangement, wheelsets/bogies, axle gears and installed ballast; diesel engine number/type/serial and supplier inclusions; hydrodynamic converter/transmission, cardan shafts, final drive, cooling, brakes and controls; cab/coupler/safety/aftertreatment configuration and actual coatings; net delivery fluid state; accepted positive measured M kg and cp_mass, calibrated weighing evidence and signed corrections; exclude fuel, operational sand, persons, temporary test loads, packaging and loose spares; actual factory/site/period and gate, supplier completion and test coverage
required_quality_disclosure	Identity/quantity and physical weight-record gaps, conditional stages, full BOM/supplier inclusions, test coverage/allocation, uncertainty, empirical limits and missing upstream
update_trigger	Gauge/axles/bogies, drivetrain/supplier modules, ballast/fluid state, coating, actual weight-record correction or acceptance regime, plant/period change
