Overhead AC-supplied electric locomotive manufacture

1. Scope and Applicability

Manufacture of new complete steel-bodied electric locomotives powered by overhead AC supply with traction transformer, power converter and asynchronous traction motors, from declared stock or bought-in bodies/modules to configuration-specific manufacturing acceptance. This is a narrower route within CPC 49511. Required running-gear/traction/outfit integration and acceptance are distinguished from optional in-house body fabrication, coating and packing. No transport service is supplied by the reference flow.

Exclude DC-only/third-rail supply, multisystem DC-capable variants, diesel-electric/dual-mode/off-wire traction-battery configurations, self-propelled passenger coaches or EMUs, incomplete bodies/bogies, retrofits, repair, resale, operation, maintenance and end of life. Auxiliary control batteries do not expand the boundary to traction batteries. Mass alone does not establish equivalent power, haulage capacity or train-service performance.

Akiem lists an AC-only configuration and asynchronous traction motors. Siemens distinguishes AC, DC and multisystem variants; its historical 2013 brochure identifies optional converter water-cooling and transformer ester. Alstom 2019 provides a DC locomotive multi-site assembly example only. Neither source supplies a universal recipe, actual current mass, lifetime or manufacturing intensity. Foreground alone is receipt-to-release manufacture; complete cradle-to-gate requires disclosed, compatible supplier upstream linkage. Scientific review remains pending.

Required qualifiers	builder/model/serial and drawing revision; overhead AC voltage/frequency and pantograph configuration; transformer/converter/motor type, rating, cooling and supplier completeness; body steel grade/route; bogie/wheelset/gear/brake configuration; cab/control/auxiliary battery chemistry; actual first-filled fluids and fixed ballast; accepted complete net M in kg from traceable actual weighing records; packaging, persons, loose consumables, sand and temporary test/transport fixture exclusions; physically measured detached integral delivered fittings; acceptance test/gate/site/period; supplier upstream and shared-resource scope

Declare every qualifier. Public broad finished-locomotive identity is used only for the narrower actual configuration. M includes installed body, running gear, traction/control/auxiliary assemblies, declared service-fluid fills and fixed design ballast. Exclude persons, loose sand/consumables, spares, removable protection and temporary test/transport loads. Separate physically measured integral detached delivery parts from separately sold spares. Catalogue mass, nominal axle load multiplied by axle count or hauled train weight cannot establish M.

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_provenance	cp_mass	Mass	kg	Retain original current calibrated actual complete-vehicle weighing or documented wheel/axle-load weighing covering all wheels of the same vehicle on the stated level method, with calibration, zero/tare, repeatability, serial/date/operator and uncertainty. Sum actual simultaneously applicable wheel/axle measurements, reconcile accepted configuration, measured fluid fills/fixed ballast and itemized temporary loads. Convert a working-order measurement to declared net scope only using traceable separately measured additions/deductions. No catalogue weight, design axle-load limit, gross/train weight or unexplained acceptance figure substitutes.
unit_conversion	utilities and chemicals	original measured property	actual row unit	Keep Mass, Volume, energy and count distinct. Meter electricity in kWh; 1 kWh = 3.6 MJ from the verified energy unit group. Convert volume or purchased item count to mass only with actual same-formulation density/temperature or measured same-configuration item mass; retain original data. No assumed fluid density or component mass.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Received specified steel stock, bought-in complete bodies, bogies and traction/auxiliary modules with declared supplier scope
starting_condition_role	Foreground receipt-to-accepted manufacturing-gate release
product_classification_scope	Complete overhead AC-only electric locomotive, not train service
recursive_input_rule	Do not generate the finished locomotive as its own input. Bought-in bodies/modules bypass included operations; actual in-house parts require their own measured component inventories
upstream_dataset_requirement	Match actual material/formulation, electrical configuration, module completeness/property, site/period and supplier production; disclose unlinked upstream
disclosure	builder/model/serial and drawing revision; overhead AC voltage/frequency and pantograph configuration; transformer/converter/motor type, rating, cooling and supplier completeness; body steel grade/route; bogie/wheelset/gear/brake configuration; cab/control/auxiliary battery chemistry; actual first-filled fluids and fixed ballast; accepted complete net M in kg from traceable actual weighing records; packaging, persons, loose consumables, sand and temporary test/transport fixture exclusions; physically measured detached integral delivered fittings; acceptance test/gate/site/period; supplier upstream and shared-resource scope

rule_id	Applies to	Rule	source_ids
boundary_foreground	all stages	Include actual manufacture, attributable rework and pre-gate factory acceptance runs. Treat test electricity, sand, support heat and waste separately when present. Exclude commercial hauling, post-gate delivery, fleet maintenance and lifetime regeneration. Include outsourced fabrication/support service only with explicit supplier scope, service unit and attribution; add each service separately.
boundary_completeness	purchased assemblies	Count each received physical assembly with its included constituent parts and fluids once. A complete bogie containing traction motors replaces duplicate motor/wheel/brake inputs. A received complete body replaces its included stock and processing, requiring a separately documented body input. Finish all actual BOM, fluid, gas, solvent, refrigerant, tooling and waste/emission identities before a completed dataset; these candidate cards are not a universal exhaustive bill.

Body fabrication feeds optional finish and running-gear/traction/outfit integration, followed by complete-configuration acceptance and conditional protection. Stages may overlap; resources are assigned once. All exchange cards are conditional on actual composition/configuration, even within required stages. Each is one physical or chemical exchange; no emission or welding/coating recipe is compulsory.

Process: Carbody stock preparation and joining (body_fabrication)

Cut/form actual certified plate and profiles, assemble underframe/body and roof, join to documented weld procedures and inspect dimensions/joints. A bought-in complete body replaces its contained stock/fabrication. Solid-wire and shielding-gas cards apply only to the actual route; other cutting/welding consumables must be separate.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_orders	shared manufacture	Separate serial/configuration orders; directly attribute measured issues/returns, meters, work hours, tests and rework first. For inseparable shared utilities use demonstrated measured causal operating time/load or coating area/layer requirement: share = order driver / sum of drivers over all covered orders. Keep period, denominator and causality. Equal vehicle count, nominal traction power or axle load is not an automatic allocation rule.
allocation_recovery	reuse and exported exchanges	Internal stock/water reuse is a transfer, not fresh input or automatic credit. Exported waste retains recipient and measured transfer, without presumed avoided production. Measure actual test electricity imports and exports separately; subtract export only under an explicit matching meter/system-boundary accounting rule with provider and timing, without a lifetime regeneration factor. Reconcile rejected/reworked units and work in progress to accepted output. Separate saleable co-products before reviewed residual allocation.

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

For each compatible configuration, net issues minus recorded returns/inventory change and justified shared allocation give attributable totals; divide by accepted unit count for q_item, then by the same measured net M for q_ref. Keep mass exchanges kg/kg and electricity MJ/kg. For mass-varying compatible serial units use attributable totals divided by summed measured accepted net masses with all serial records retained. Separate different supply voltages, traction/cooling, bogie layout, body/finish and supplier completeness. Unknown amount is a gap, never zero; no traction-power, nominal axle-load or catalogue-mass conversion is inferred.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_mass	cp_mass	Implement mass_record_provenance using actual current traceable physical weighing and itemized net-configuration reconciliation. Every included wheel/axle belongs to the same unit and state; reconcile measured detachable fittings/fills and ensure no omitted/double-counted weight. Missing original method, calibration, state correction or positive M blocks a complete quantitative dataset and requires review/new measurement.	original weighing and configuration correction ledger
quality_bom	complete configuration	Reconcile all actual body, bogie/wheelset, traction, brake, auxiliary/cab/control and service-fluid masses to accepted net M. Record purchased assembly inclusions; no duplicated motors in bogies or transformer/cooling prefills. Add actual omitted parts and exchanges before completion.	complete drawings/BOM/receipts/weighing/SDS
quality_balance	amounts and species	Retain calibration, energy meters, issues/returns/reuse, measured fluid composition/density, waste manifests and actual emission method/species/medium. Define empirical QA limits from applicable measured records or verified comparable sources. No universal manufacturing intensity, vehicle mass or burner emission factor is supplied.	actual meter/stock/mass balances and uncertainty
quality_coverage	dataset	Disclose period/site/configurations, conditional absence, subcontracting, identity/quantity uncertainty, range gaps and missing supplier upstream. Historical product/production examples do not establish present product certification or this locomotive M. This PCR specifies future record requirements; no actual locomotive weighing or plant inventory has been certified.	coverage and evidence limitations register

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference	reference product	Require covered complete overhead AC configuration and positive actual net M from cp_mass with mass_record_provenance. Reject nominal axle load, catalogue mass, train weight, operating-service equivalents and missing configuration corrections. Missing actual record evidence requires scientific/data review before a completed quantitative dataset.
validate_atomic	all exchanges	Verify atomic physical/chemical identity, public reference property/unit group, route/composition/state and supplier boundary. Pantograph is not battery foil, traction transformer is not a rated distribution transformer, motor inside bogie is not a second input, ester is not mineral oil, process water is not environmental withdrawal/effluent. Keep unsupported UUID blank.
validate_measurement	all amounts	Verify amount, original unit, collection and q_item/M conversion, same serial/configuration/site/period, accepted count, calibration and justified allocation denominator. Energy, volume and item count never become mass by renaming the property. Unknown is not zero.
validate_species	conditional elementary releases	Require actual attributable factory-support species and medium. Selected fossil CO2, NO and NO2 are immediate air-unspecified releases; verify fossil provenance for CO2. Do not substitute total NOx, N2O, nitrogen/nitrite, biogenic CO2, water/soil or long-term flows. Captured filter dust is a waste; no exhaust is mandatory for this electric traction route.
validate_release	vehicle acceptance	Trace actual structural/electrical/brake test procedures, results, rework and release authorization for the same configuration and applicable jurisdiction when claimed. Historical brochure or other manufacturer/model certificate does not certify this vehicle. No universal voltage, brake threshold or test-energy saving is imposed.
