Deployment of The CRM 3000


Dual Inventive was approached by Translink in early 2022. They were interested in the CRM 3000 as they were looking for a remote digital solution to monitor rail temperature across their network in Northern Ireland – from Londonderry in the Northwest to the border with the Republic of Ireland just south of Newry.

Translink wanted a digital solution:

  • That was easy to deploy
  • That would monitor the temperature of the rail to help safely manage high-rising rail temperatures
  • To provide real-time data to help make informed choices
  • To receive notifications and alerts when the temperature reaches a set threshold
  • To reduce the need to deploy staff trackside

The Solution

Dual Inventive’s CRM 3000 is a compact remote temperature sensor that attaches to the web of the rail with a quick-fit magnet. Its robust construction is fully weatherproof and will last up to 5 years in track without the need for any servicing or recalibration.

The CRM 3000 takes a temperature reading every 5 minutes and transmits these readings every hour to Dual Inventive’s secure online platform, via the Vodafone Business Narrowband Internet of Things technology (NB-IoT) network. This enables the end user to set alarm thresholds and create graphics-based dashboards to remotely monitor the network, reducing the requirement for staff to be trackside in a high-risk environment.

The device is a low-cost alternative to other solutions on the market and is offered on a lease contract with a minimum term of 2 years. The price includes the device and access for up to 25 users on the online platform and via the App which is available from Google Play and Apple store.

The CRM 3000 is already in use across multiple networks in the UK and Europe and has full Network Rail Product Approval.
