  • Streaming event recorder data –  With Violet, your locomotive information populates on your computer or mobile device in real time. Eliminate the need to go to locomotive to download data. By having streaming event recorder data without retrieving a download, you avoid on-site hazards and save time and money.
  • Your data when you need it most -- Violet software displays PTC data, train location, thumbnail snapshots, speed, and event recorder information in streaming, second-by-second format.
  • Data security -- Onboard system data is secured up to the moment of power loss. This assists in accident situations where event recorder may be inaccessible (fire, water, etc.).
  • Single agnostic software that displays data from Violet and other inputs, regardless of the other devices' model or age. Streamline your data review process by compiling information in one place for ease of use. It's your data, so you should be able to access it and utilize it.
  • No files, no downloads, no headaches -- Your information is secure in the Violet cloud-based software. Information can be shared through the Violet software without traditional files or downloads. This mitigates the risk of your sensitive DVR images and videos ending up in the wrong hands. Overall, your locomotive data security more secure than ever before.
  • Backwards compatibility for easy installation -- Installation utlizes existing materials to ease installation and reduce cost.
  • Sustainable technology for future expandability – over-the-air software updates mean you keep your locomotive in service and don’t impact your velocity. There is no need to shop locomotives to implement new software.
