Tasmanian Railway – selcall monitoring

The Problem

Train Controllers at Tasrail received incoming radio notifications (selcalls) from various infrastructure on the rail network. This infrastructure includes locomotives, track vehicles and track temperature sensors. The software that logged these notifications was outdated and not compatible with modern hardware or operating systems. This made maintaining and updating the system more and more difficult as replacement hardware becoame obsolete.

The Solution

We developed a new piece of software to replace the old one. The new software receives selcalls from the radio device through a serial port and inserts them into a central database. These selcalls can then be viewed from any workstation on the network via the Selcall Monitor. The software can differentiate between standard and emergency calls and can be configured to send out alerts via email or SMS when specified call types are received.

The Outcome

The Selcall Receiver, receives selcalls through a serial interface and inserts them into the database.

The Selcall Monitor, displays selcalls as they are received. Selcalls are colour coded and displayed on the left or right monitor depending on the type and status of the selcall.

The Selcall Data History interface displays all calls that have been removed from the monitor. Users can search the selcall’s and export them to CSV for further ananlysis.
