Eastern & Atlantic Numbering System

The Eastern & Atlantic numbering system was developed by Howard White, similar to the classification system.

The first 1150 numbers were reserved for express passenger locomotives, while 1151-2500 were reserved for slower passenger locomotives. 2501-5300 were reserved for dual purpose locomotives. 5301-8000 were reserved for freight-only locomotives. 8001-8300 were reserved for bankers, 8301-8700 were reserved for Transfer locomotives, and 8701-9700 were reserved for switchers.
