The TRIMET LIVE SCANNER and the TRIMET SCANNER TWITTER are maintained and operated by 3 Transit Bloggers, HERE HERE and HERE
All information posted to the twitter is based on actual dispatch communications. We do not investigate any of this information, use at your own risk.
Neither the live scanner or the twitter account has any association with the Trimet Transit District who in reality does not appreciate our services and would be more than happy if we disappeared.
THIS IS THE NEW FEED
No recordings however
The TriMet Scanner is provided to the general public free of charge. The twitter account @trimetscanner is used by volunteers who donate their time to listen to the radio channels of TriMet, the public transportation agency in the Portland Metro Area.
800 mhz (Most MAX Light Rail communication, Bus Dispatch, Fare inspectors)
TuneIn Radio also has the 800 mhz scanner available within their android, iphone, and web app.
700 mhz (TriMet Bus to dispatch communication)
22xx - G4S Security
91xx - Bus Supervisor
94xx - TriMet Fare Inspectors
95xx - Max Light Rail Supervisor
97xx - Portland Streetcar Supervisor
99xx - TriMet Lead Supervisor (Above Light Rail and Bus Supervisors)
01-33: Center Garage
34-66: Powell Garage
67-99: Merlo Garage
Extra Service buses follow the same train pattern, but are assigned the Line number of 7, as there is no line 7 in the system at the current moment.
Some buses will run other lines than what they are designated, which is referred to in TriMet's world as "running an offline route."
TriMet Mapper - Interactive Version (Map mode, best used for desktops, or if you want a full overview of the system). Block ID List - Helpful to see what block (line/train) is running on a daily basis.

Understanding the chatter
Buses
How to Identify
Each bus in TriMet's system is identified by either the bus number or by the block (or line/train) they are running. The first two numbers identifies the line they are running, while the last two numbers identify the order (train) the bus came out of the garage. Each garage is assigned a set of trains to ease confusion, broken down as follows:01-33: Center Garage
34-66: Powell Garage
67-99: Merlo Garage
Extra Service buses follow the same train pattern, but are assigned the Line number of 7, as there is no line 7 in the system at the current moment.
Some buses will run other lines than what they are designated, which is referred to in TriMet's world as "running an offline route."
