Brs mail
You're referring to the BR Standard Mail (BRSM) system!
BR Standard Mail, also known as BR Mail, was a postal system used in the United Kingdom from 1965 to 1990. It was introduced by the British Railways (BR) to provide a standardized system for sorting and delivering mail.
The BRSM system used a combination of letters and numbers to identify mail routes, sorting offices, and delivery points. The system was designed to be more efficient and cost-effective than the previous system, which relied on a complex network of railway lines and sorting offices.
The BRSM system consisted of several key components:
- Mail routes: Mail was sorted and dispatched along specific routes, identified by a combination of letters and numbers.
- Sorting offices: Mail was sorted and processed at designated sorting offices, which were located along the mail routes.
- Delivery points: Mail was delivered to specific points, such as post offices, railway stations, or other designated locations.
The BRSM system was used until 1990, when it was replaced by the Royal Mail's (formerly Post Office) modernized sorting and delivery system.
