Innovation from Inside the Industry

Having extensive experience working with locomotive builders, operators and rail customers, Railspire’s innovative team appreciates real world operational challenges: the safety imperative the nights and weekends the hot and cold the rain and snow the impacts of tonnage the long asset lifetimes

Our Approach

The Railspire team collaborates with customers to utilize technology and bridge the gap between traditional operations and emerging technologies.


We provide operator-assisted and mission-based solutions for:

  • Small to large scale fleets
  • Locomotives new or old
  • Locations remote or urban
  • Road and yard operations


Whether starting with simply one locomotive in one location or equipping your entire fleet, Railspire technologies scale and improve as customers’ requirements grow and change. We design with the mindset of adopting and adapting to technologies and use-cases that have yet to be imagined.


We recognize that some technologies are created in search of a problem, but at Railspire we apply technologies to tangible applications that address existing challenges. We enable you to operate how you want, not constrained by existing operating procedures and paradigms.
