# Steel high-sided open railway freight wagon manufacture

## 1. Scope and Applicability

This candidate PCR governs manufacture of a new complete non-self-propelled steel high-sided open railway freight wagon with integral flat floor, fixed end walls, high side walls and side doors, with declared unpowered bogies, brakes and couplings. The Eanoss manufacturer original establishes this substantive body boundary. It is narrower than CPC49533 and does not cover that entire classification leaf. Exclude boxcars, flatcars, hopper wagons and discharge-gate designs, tank/refrigerated wagons, other body architectures, locomotives, passenger vehicles, bare bodies/bogies, rebuilding, repair and freight transport services.

Foreground starts at actual received specified stock and completed supplier modules and ends at accepted configured empty wagon at the declared plant gate. Manufacturing acceptance belongs here only for attributable actual tests; operational loading/unloading/haulage, cargo yield, track infrastructure and life-cycle service are outside. No empirical mass, recipe, process intensity or life is prescribed. Scientific review remains pending. Sources: `tatra-model`, `tatra-factory`, `greenbrier-2022`.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Manufacture a specification-conforming complete high-sided open freight wagon |
| How much | 1 kg accepted net empty wagon output; divide per-unit manufacturing records by actual M |
| How well | Meet actual drawing, body/door, running-gear, brake/coupling and release acceptance criteria. Equal mass does not imply equal payload, strength, loading volume or transport service. Manufacturer model capacities and compliance claims are not imposed. |
| How long or cycle | One manufacture/acceptance cycle; no operational lifetime |
| reference_flow_link | finished_machine |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Accepted complete unpowered steel high-sided open railway freight wagon |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | producer/model, serial and drawing/BOM revision; high-sided open body, integral flat floor, fixed ends, side doors and locking/access fittings; steel grades and supplier completion; gauge, bogie/axle/wheelset arrangement, suspension, bearings, brakes and couplings; coating chemistry and actual heater/blasting route; complete empty net M kg and cp_mass, calibrated rail/wheel weighing and signed configuration corrections; retained bearing lubricant; exclude cargo, test loads, personnel, fixtures, packaging and loose spares; actual site/period and gate, supplier inclusions, conditional absence and outsourcing |

M includes the actual integral underframe, floor, high sides/fixed ends, side doors/locks, bogies/wheelsets, suspension/brake/coupling/access fittings, coating and retained bearing lubricant. Cargo/payload, temporary test weights, people, fixtures, removable wrap and loose spares are excluded. The manufacturer separately reports tare, loaded weight and capacity: catalogue tare is a configuration example, never the measured accepted M. Source: `tatra-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 original serial-linked actual empty-wagon calibrated rail weighing or wheel-load measurement, calibration/instrument, all wheels/supports, tare and static procedure. Sequential wheel measurements require checked support coverage and repeatability. Reconcile actual detached integral parts and temporary loads with measured corrections and signed BOM/weight balance. Catalogue tare, payload, gross laden weight, axle rating or sums of nominal component masses do not establish M. |
| `energy_conversion` | electricity | Net calorific value | MJ | Meter attributable electricity intake; verified kWh unit conversion is3.6 MJ/kWh. Nameplate kW is not energy; site/voltage/mix matching is required. |
| `gas_air_volume` | gas; air | Volume | m3 | Retain actual metered reference-temperature/pressure/compressibility volume. Gas supply and compressed-air test media are separate routes; use measured gas composition and physical state for any conversion to mass/energy, never generic density or nominal tank volume. |
| `coating_species` | finish | Mass | kg | Separate actual coating base/hardener/solvent/grit, retained dry coating and waste. Emitted mixed xylenes require actual CAS-specific emission evidence and immediate air medium; total VOC or HAP is not that species. Fossil CO2 requires actual heater fossil-carbon basis, not upstream inventory. |


## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Received steel plate/sections and supplier-completed body, running gear and fittings with inclusions declared |
| starting_condition_role | Actual receipt-to-empty-wagon manufacture |
| product_classification_scope | Steel high-sided open railway freight wagon only |
| recursive_input_rule | Bought body/bogie replaces its included fabrication; never recursively manufacture a complete wagon as its own input |
| upstream_dataset_requirement | Link actual provider, stock grade/route and module scope; disclose upstream and outsourced gaps |
| disclosure | producer/model, serial and drawing/BOM revision; high-sided open body, integral flat floor, fixed ends, side doors and locking/access fittings; steel grades and supplier completion; gauge, bogie/axle/wheelset arrangement, suspension, bearings, brakes and couplings; coating chemistry and actual heater/blasting route; complete empty net M kg and cp_mass, calibrated rail/wheel weighing and signed configuration corrections; retained bearing lubricant; exclude cargo, test loads, personnel, fixtures, packaging and loose spares; actual site/period and gate, supplier inclusions, conditional absence and outsourcing |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `boundary_stages` | all processes | Include actual producer fabrication/assembly and attributable acceptance resources once. Purchased complete bogies/body replace included stock/parts/processes; report conditional absences and omitted actual BOM items before quantitative completion. | `tatra-factory`; `tatra-model` |
| `boundary_use` | acceptance/downstream | Construction-only documented acceptance is inside; revenue haulage, loading/unloading, track works, operation maintenance/rebuild and end-of-life outside. External locomotive trial service, if used, is a separate measured service link, never wagon engine fuel. | `tatra-model` |
| `boundary_upstream` | dataset | This foreground is not automatically complete cradle-to-gate. Declare actual outsourcing and physical transport/service links and require suitable upstream datasets; record gaps without substituting generic exchanges or zeros. |  |


## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| `body` | Underframe and dry-freight body fabrication | conditional | Actual fabrication inside the declared manufacturing boundary. | foreground | one accepted complete unit normalized with M |
| `running_gear` | Running gear, brake and coupling integration | required | Each accepted unpowered high-sided open wagon with the declared bogie and brake configuration. | foreground | one accepted complete unit normalized with M |
| `finish` | Conditional surface preparation and coating | conditional | Actual shot blasting/coating/heating at the reporting plant. | foreground | one accepted complete unit normalized with M |
| `outfit` | Freight fittings and final assembly | required | Each declared complete dry-freight configuration. | foreground | one accepted complete unit normalized with M |
| `acceptance` | Empty-wagon inspection and acceptance | required | Each finished accepted complete empty wagon. | foreground | one accepted complete unit normalized with M |
| `packing` | Conditional delivery protection | conditional | Actual removable protection shipped at the declared gate. | foreground | one accepted complete unit normalized with M |

Actual body fabrication feeds running-gear integration, conditional preparation/coating and side-door fitting, then empty acceptance and conditional protection. Declare actual station order and supplier completion. Required process stages do not require every example chemical/component: each row applies only to an exact actual independent supply or species; add every omitted actual component, heat, chemical, waste and measured emission separately.

### Process: Underframe and dry-freight body fabrication (`body`)

Cut/form/machine specified steel stock and weld underframe and declared integral flat floor, fixed end walls, high side walls and side doors. Bought complete underframe/body replaces included fabrication. Record actual steel grade, filler and shielding recipe and welding quality; no casting/forging/heat treatment assumed in-house.

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `allocation_orders` | shared resources | Avoid allocation by subdivision and actual order/serial stage metering first. Allocate remaining shared resources by demonstrated causal metered machine time, coated area for an identical coating/operation or measured test use, with original numerator/denominator and sensitivity. Do not assign mixed wagon bodies equally per unit or nominal tare. | `ghg-allocation` |
| `allocation_scrap` | steel offcuts | Measure generated steel offcuts/returns, separate internal recirculation and transferred waste once, preserve recipient/legal treatment state and actual coproduct status. No automatic avoided-virgin-steel or recycling credit. A demonstrated sold coproduct needs independently reviewed allocation with actual causal evidence and consistent upstream boundary. | `ghg-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 |  |

Collect attributable net exchanges by actual serial configuration, subtract returns and inventory changes, justify shared allocation and divide by accepted unit count for q_item, then by the same actual empty net M. Preserve kg/kg, gas/air m3/kg and electricity MJ/kg. For compatible serial wagons with real M variation use total attributable exchanges divided by summed measured accepted net masses, retaining every serial. Separate incompatible body/gauge/bogie/brake/coating and acceptance routes. Unknowns remain gaps.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `quality_mass` | cp_mass | Implement mass_record_origin with actual calibrated complete empty-unit measurement and signed corrections. Missing original measurement method or unbalanced configuration blocks quantitative completion. | original serial/calibration/weight/BOM balance |
| `quality_bom` | all processes | Reconcile underframe/floor/end/side walls/doors, bogies/wheelsets/brakes/couplings/access, coating and retained lubricants. Supplier complete assemblies include constituents once; add omitted actual constituents and resources before completeness claims. | drawings, supplier inclusions, actual records |
| `quality_species` | finish | No compulsory VOC/NOx/species or heater combustion is inferred. Actual formulation, direct outlet, detection limits, operating coverage and measured conversion basis are required; distinguish indoor/soil/long-term/isomer from specified immediate-air species. | SDS/speciated outlet/gas records |
| `quality_evidence` | dataset | Declare site/period/gate, original lineage, empirical QA limits, conditional absence, allocation, uncertainty, identity/quantity/upstream gaps. Establish empirical ranges from actual calibrated records or independently verified compatible evidence, never invented mass/yield/life. PCR check establishes declared relations only, not scientific approval or actual factory records. | source and coverage register |


## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `validate_reference` | finished_machine; cp_mass | Confirm complete steel high-sided open wagon, empty positive actual net M, physical calibrated mass_record_origin, exact configuration and fixed1kg output normalization. Reject cargo/gross laden/catalogue tare as M and other body types. | `tatra-model` |
| `validate_rows` | all inventory rows | Each exchange has one identity/property/unit and exact direction/type, shared denominator and linked protocol/rule. Respect actual public reference property, compartment and route, official Chinese names; blank identities remain review gaps. No generic category row. |  |
| `validate_balance` | all processes | Reconcile stocks, supplier inclusions, assembled accepted mass, retentions and waste, shared driver and actual test scope. No double-counted bought bogie and constituents or recycled steel credit. All unmeasured quantities/conditional routes and missing upstream prevent unqualified completed cradle-to-gate claim. | `ghg-allocation` |
