What changed
Fetched wikitext for List of reporting marks: A through Z from the English Wikipedia MediaWiki API. Read only the reporting-mark tables on those pages. Removed wiki markup, reference tags, and editor comments. Kept the displayed mark, including ampersands such as A&GW, rather than the hidden sort key. Normalized marks to uppercase and dropped rows that are not 1–4 letter reporting marks. Split each company cell into an owner string and a notes string. Year ranges in parentheses stay with the owner. Other parenthetical clarifications move to notes. Preserved Wikipedia's arrow (→) as a name succession and semicolon as more than one listed company. Classified each row from its section heading: operating railroad or private owner. Assigned a suffix class from the final letter: X private equipment, U container, Z trailer, otherwise railroad. Merged duplicate marks into one record. Did not add equipment-register fields, build dates, dimensions, capacities, or any Railinc data.
Columns
- mark — the reporting mark, uppercase, ampersands kept.
- owner — company names as the Wikipedia page listed them. An arrow is a succession. A semicolon is more than one company.
- notes — parenthetical clarifications that are not a year range.
- category — railroad or private, from the Wikipedia section when the page has one, otherwise from the suffix.
- suffix_class — private_x, container_u, trailer_z, or railroad.
- source_page and source_title — the Wikipedia list page.

Left out on purpose
This pipeline does not use Railinc, UMLER, the Official Railway Equipment Register, or the P&WRR reporting-mark list. There is no build date, dimension, capacity, or pool column, because those fields are not in the Wikipedia tables and they are not going to be filled from a proprietary system.
