The Eastern Region (ER) Technical Attachment (TA) series began in 1969. Publication numbers were not assigned to TAs until 1971. For consistency across this webpage and associated file naming conventions, the publication year and number are based on the published date. From 1971 through mid-1976, TA numbers were derived from the publication date. When multiple TAs were published on the same date, they were differentiated using letter suffixes (e.g., A, B, C). However, in practice, numbering was not always sequential and sometimes diverged from this format. Beginning in 1998, a new numbering system was introduced in which TAs were assigned sequential numbers starting at 1 for each calendar year. This revised webpage includes publications from 1969 to 1998. The following notes document known discrepancies, caveats, and clarifying information to promote transparency and historical accuracy.
