# New mainline AC-traction diesel-electric locomotive manufacturing

## 1. Scope and Applicability

Manufacturing one complete new diesel-only mainline heavy-haul diesel-electric locomotive with AC induction traction: actual underframe/carbody fabrication, surface finishing, supplied railway diesel prime mover/main alternator and rectifier/DC-link/inverter chain installation, bogie/wheelset/traction motor and brake assembly, cab/cooling/electrical outfit, bounded factory/static and acceptance testing and corrected net-mass release. Select one actual released locomotive number, gauge, axle/powered-axle arrangement and installed configuration. This scope is narrower than CPC49512.

Exclude DC-traction locomotives, externally powered electric locomotives, battery/hybrid traction, gas/diesel dual-fuel, diesel-hydraulic/mechanical drive, shunters, multiple units, separately sold parts, overhaul and remanufacture. Auxiliary starting batteries are included when fitted and do not imply hybrid traction. Exclude commercial train haulage, tonne-km, operational fuel/maintenance, tracks/depots and end of life. Actual manufacturing-support transfers and acceptance runs require explicit measured endpoints, loads/time and coverage; service fuel or sand stores are not manufacturing consumption or net output mass.

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Actual released structural steel and supplied engine/AC traction, bogie and outfit parts received at declared sites. Steelmaking/rolling, engine/motor/electronics/part manufacture upstream unless explicit site measured fabrication; supplier-ready state stated. |

| product_classification_scope | Manufacturing one complete new diesel-only mainline heavy-haul diesel-electric locomotive with AC induction traction: actual underframe/carbody fabrication, surface finishing, supplied railway diesel prime mover/main alternator and rectifier/DC-link/inverter chain installation, bogie/wheelset/traction motor and brake assembly, cab/cooling/electrical outfit, bounded factory/static and acceptance testing and corrected net-mass release. Select one actual released locomotive number, gauge, axle/powered-axle arrangement and installed configuration. This scope is narrower than CPC49512. |
| recursive_input_rule | No recursive purchased complete locomotive as body/engine stock. Purchased shells, bogies/power/cab packages replace contained stocks/work; internal transfers counted once with exact handover/supplier scope. |
| upstream_dataset_requirement | Expanded assessment requires compatible actual steel/chemical/engine/bogie/electrical/part manufacture, utilities, outsourced finishing, inbound/support transport and waste treatment datasets with provider/version/coverage. This measured foreground alone is not complete cradle-to-gate. |

Moving versus stationary assembly is not a mandatory technology choice or numeric allocation rule. | wabtec-moving-2024 |
| boundary_tests | acceptance | Only bounded manufacturing acceptance/test runs and support transfers included, with actual track/endpoints/load/time and test-fuel consumed separated from retained delivery fuel. External test-track/tow services need measured provider scope, fuel/utility coverage and no duplicate service-contained consumption; tracks are not automatically included infrastructure. |  |
| boundary_packages | traction; running | Exact engine/alternator and powered-bogie supplier containment controls duplicate removal. If a complete powered bogie is purchased, omit its contained frame/wheelset/motor/gear/brake from separate supply cards and add the exact measured complete bogie instead; internal finished bogie transfer not a second output reference. |  |

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| allocation_causal | shared_operations | Subdivide work orders by accepted locomotive configuration and stage first. Shared cutting/welding/coating, lifting, mixed-model assembly and test rigs use actual exchange-specific metered causal demand/load/time from cp_allocation. Reconcile all served work to supplied totals; no universal installed mass, rated power, line speed or production-count share. | wabtec-moving-2024 |
| allocation_rework | configurations | Attribute actual rejected-part/rework burden to accepted construction. Each configuration retains independently measured M and matched numerator before pooling by disclosed measured accepted mass. Any residual physical/economic fallback requires actual driver/cost/market records, sensitivity and review; no invented percentages. |  |
| allocation_recovery | outputs | Recovered internal steel/abrasive/flux/water is transfer, not automatic co-product or avoided production. Outgoing wastes keep condition, treatment and responsibility. Saleable co-product needs actual quality/market and reviewed allocation; no future locomotive-recycling credit. |  |

q_item is measured attributable same-configuration exchange after issue/return, stock and rework reconciliation divided by matched accepted units. Keep kg, MJ, supplied pane m2 or actual engine Item(s) numerator; independently measured engine kg closes installed mass rather than numerically adding items to kg. Volume/density, part count/mass or supplied formulation/concentration conversions need actual same-product/state evidence with uncertainty. No rated-power-to-mass or assumed catalogue weight.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| quality_weighing | finished_machine | cp_mass requires actual current accepted complete-locomotive weighing with a calibrated railway scale/traceable wheel- or axle-load measuring system appropriate to the method used. Keep original serial/configuration, date, instrument/calibration/tare, all wheel/axle identifiers/readings, repeated checks and actual static/dynamic method conditions. The signed result must account for every axle once, support total mass without duplicated wheel/axle sums, and correct documented actual fuel/sand/test fixtures and other excluded stocks. Independently reconcile supplied installed engine, body, bogie, traction equipment, outfit and retained technical fluids against complete fit-list, actual measured corrections and uncertainty. Missing actual weighing or corrected delivery-state evidence blocks dataset use. Catalogue operating/adhesion weight, axle limit times count, rated power, fuel-full weight and guessed residual cannot replace M. | calibration and original locomotive-specific axle/wheel weighing; independent installed BOM |
| quality_delivery | finished_machine | Reference output includes complete declared fitted body/bogies/traction/cab/cooling/braking/safety and auxiliary starter battery with retained technical oil/coolant/electrolyte once. Exclude fuel/sand service stores, persons/cargo, packaging, detached spares, temporary test rigs/load banks and transport attachments outside released product. Identify any permanent designed ballast in installed configuration; actual measured mass only. Document dry versus wet equipment and each measured tank/net correction; no assumed empty/full tank. | released fit-list; supplier containment; measured tank/correction and acceptance state |
| quality_engine | diesel_engine | Keep actual supplied engine count under public Number of items and independently measured received dry/installed kg, model and serial. Railway prime mover class43110 differs from road-propulsion class43123 which excludes railway/tram rolling stock. Supplier contained alternator, starter, cooling or fluids must be reconciled to independently supplied items and whole M, with no second alternator/engine counted inside package. Taxonomy source supports distinction only, not engine weight or railway performance approval. | un-engine-scope; supplier model/serial and independent engine weighing |
| quality_identity | flows | Require actual grade, chemical/formulation, route/state, voltage and supplied configuration; preserve public properties. Traction motor public expert mass-share example is not this locomotive inventory. Cable/battery energy property cannot be rewritten kg; same-product conversion evidence required or identity gap retained. Mineral oil not PAO, formulated coolant not pure glycol, dry traction sand not unqualified silica. PM/xylene/fossilCO2/NO need species/CAS/source and immediate-air medium evidence; no totalNOx as NO or totalVOC as xylene. | supplier certificates/SDS; outlet samples and physical identity records |
| quality_tests | acceptance | Retain actual current released factory plan/results for weld/dimensional inspection, electrical insulation/controls, prime mover/traction chain, brake/air leak, cooling and static/load/acceptance running tests where applicable, plus exact loads/duration/endpoints and rework. Current authority/operator approvals only when actually established. Progress brochure case emission class, maintenance interval, power, fuel capacity and operating mass are not generic acceptance thresholds or lifetime rules. Separate test fuel consumed from retained delivery fuel and technical fills; no assumed emission factor. | released configuration-specific test records; progress-sd70ace |
| quality_coverage | dataset | Every actual fit-list/route exchange needs measured/calculated/estimated/missing/excluded/not-applicable disclosure. Add specific cards for actual additional couplers/draft gear, air reservoirs/pipes/hoses, exhaust/silencer/aftertreatment when fitted, resistor grid/fans, controls/safety cab parts, joining chemistry, separate coolant waste, packaging and contracted support/treatment. No mixture/collection row. Foreground records and compatible upstream modules required before complete-data or cradle-to-gate claims. | complete fit-list/work orders; coverage and stock/meter closure; uncertainty |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validation_reference | finished_machine | Require 1kg accepted complete configured output and same-unit cp_mass actual weighing/net corrections with independent fit-list mass balance. The finite declared q_item/M check is not a physical weighing or scientific approval. |  |
| validation_basis | inventory | Match configuration, accepted count, reporting cycle, numerator units and linked collection to normalize_mass. Engine Item(s) must retain separate actual kg evidence; no count/property rewriting. |  |
| validation_packages | manufacturing | Audit engine/alternator/powered-bogie/cab supplier scope and prefill against independent installed BOM. Reject duplicates and missing supplied interfaces. Check AC induction versus DC, hybrid/dual-fuel and excluded service-route differences before use. | progress-sd70ace |
| validation_release | elementary | Verify actual post-control species/CAS, fossil provenance, medium/submedium/time and test boundary. NO is not NO2/N2O/totalNOx; captured dust not air release, wastewater not freshwater resource. Expand actual additional emissions when measured, never make all conditional releases mandatory. |  |
| validation_completeness | dataset | Keep unresolved identities and missing physical records explicit. Complete actual weighing/corrections, route/acceptance records, fit-list and supplier/utility/transport/treatment coverage before use; structural pass cannot confer methodology approval or complete cradle-to-gate coverage. |  |
