Alerts NRSDB will alert users by email when an ESR is Imposed, Amended or Withdrawn. Email Alerts NRSDB will soon cover the entire network and we average about 5 events (Impose, Amend or Withdraw) each day. Most users do not need to receive every single alert. Some are only interested in a route or a particular line. For example C2C exclusively run on the Southend line and definitely do not want to hear about restrictions in Wales! To facilitate this every user can control which alerts they receive by "subscribing" to Lines of Route (LOR). We have 843 LORs available. This is controlled from the User Profile via the top-right menu     PLEASE NOTE: the Route Subscriptions only applies to Blanket Speed restrictions. You MUST set your ESR Alert Subscriptions to receive alerts.
