Atcs Monitor

ATCS is a radio control protocol used by US railroads to control wayside systems and train signals. ATCSmon is a program used to decode and display the information. Using a scanner set to a ATCS channel, the audio is plugged into a computer running ATCSmon. ATCSmon will then decode the audio and can display the status of occupied track, switch positions and signal aspects.

ATCS Monitor: Download and Installation. To use this program click on the link below to download the Zip file onto your computer. This file includes the layout files for the Ft Wayne Metro Area that includes the CSX (former B&O) from Ripley to Sherwood because of it's close proximity to Ft Wayne, and the MCP information to be added. Able software called “ATCS Monitor” it is possible to decode this information and display it. Monitoring these signals is equivalent to monitoring the railroad personnel’s voice communications on a scanner. As with voice, we can only hear as far as our antenna locations will allow. When the stations is blue, con-trol messages sent from.

ATCS operates in the 900mzh range and consist 8 defined channels with a uplink and downlink frequency. The BCP (Base Control Point) is centrally located and sends radio commands out to the MCP (Mobile Control Points). The MCPs are the track wayside devices and send status messages and block occupancy back to the BCP.

Install ATCSmon on Linux (or Mac) using Wine

ATCSmon can be installed on linux and runs flawlessly with the help from Wine. Wine is an open-source compatibility layer that enables Windows programs to run Linux operating systems. Visit winehq.org for more info on Wine.

Instructions from Ubuntu 18.04

Downlown ATCSMonitor from groups.io/ATCSMonitor file section

You will need Wine and winetricks installed for ATCSmon to work

Use winetricks to install MDAC 2.8 and Jet 4.0 ddls which are both required for ATCSmon.

To install winetricks, run in terminal
sudo apt-get install winetricks

To install MDAC 2.8 and Jet 4.0 run:
winetricks mdac28 jet40

You should now be able to execute the ATCSMon installer .exe
wine ./atcsinstall.exe

I'm one of those guys who has used a VPN to connect my Droid 2 to my home computer. There's a variety of programs out there - many of them free. Personally, I use a program called 'TightVNC' on my PC and a similar VNC program on my Droid 2. This allows me to see (and even manipulate) whatever is on my home computer's screen. I'll simply load up ATCSmon before I leave to go railfanning, and connect via my phone once I'm out 'in the field.' Luckily, the area I usually railfan has a pretty good collection of servers, so I have a very clear picture of what is coming my way.
I'm here to tell you... You get the ATCS monitor screen picking up while you're out railfanning, so you're watching from the field, and about the only thing you need a scanner for is to know what train symbol is going by. I can sit there, and listen to railfans talk about going home because it's so slow, and then I laugh because there's a flood of 3 or 4 trains headed my way - and I know right where they are, thanks to ATCS.
