Railway Operating Centre, or R.O.C. (pronounced: [ɑː(ɹ) əʊ ˈsiː] or [ɹɒk]) is a web application used during the On Our Lines SimSig Sessions. It simulates a combination of a GSM-R and Connect Radio terminal, as well as a telephone concentrator. ROC allows easy communication between Signallers, Controllers and other 'non-playable characters' by automatically placing and routing phone calls between different users. It interfaces with Discord which provides the voice channel functionality.

ROC is an open source project released under the MIT license, and the repository is available to view on GitHub. It is maintained by the On Our Lines Community, and new contributors are always welcome! The code base is predominantly written in javascript, using the Vue and Nuxt frameworks.

ROC can be used outside of our 'official' SimSig Sessions, however no support is provided and it will not be configured to your requirements. You will also not be able to access the Control roles or admin functionality. You are, however, more than welcome to set up your own instance of ROC.

Getting Started

The splash screen for ROC users are presented with before logging in.

To use the Railway Operations Centre (ROC) you must first join the On Our Lines Discord server and claim the SimSig role. This will provide access to the SimSig voice channels which are used for ROC. You should then join the #on-our-simsig-lobby voice channel, before navigating to ROC in your web browser of choice.

Authentication is via Discord - when you click log in, you will be asked to login to Discord (if you are not already) and then give ROC permission to use your account - this is just to let us move you around voice channels, and does not change anything else on your account.
