LATA
In some TRUST messages, the Line And Terminal Address (LATA) of the inputting terminal is shown, usually when the event (movement or cancellation) is manually reported, or is reported through TOPS.
LATAs are in the format AANNNNN:
- AA is a two-character string which indicates the type of terminal and its sequence number
- NNNNN is the TOPS Responsibility Area (TRA) that the user is within

When TOPS was introduced, a TRA covered a geographical area. Since privatisation of the rail industry, TRAs are now operator-centric, rather than geography-centric.
