Providing valuable solutions for a diverse group of customers has always been our mission. This commitment to your success dates back to 1975 with the launch of Central States Thermo King (CSTK). From the beginnings of CSTK we founded Central States Special Products in 1985 to service the rail industry. It was not long before our geographical service area had grown far beyond the central states. 1995 brought a name change to better reflect our core competencies and areas we serve. The Velociti name was chosen to represent our commitment to superior service and international support.


Whether you manage a class one railroad or short line operator, our products and experts will help make your job easier and improve comfort for your crews.

HVAC Fleet Evaluations

Repairs and maintenance programs can reduce downtime and improve operating efficiency. At Velociti Rail, we understand the need to ensure prompt, quality repairs on your locomotive HVAC fleet.

Utilizing the Velociti Rail scorecard system, HVAC units are graded on condition upon arrival. Use of this tool provides insight into future demands of overhauls, fleet upgrades and unit lifespan.

The score card points system is flexible, the points assessed can be manipulated to achieve your fleet goals. Using this system provides a process for qualifying the components based on age, failures, obsolescence and lifespan enabling your to make decisions based on current unit conditions.

Velociti can assist you in developing a strategy that fits your requirements.

Overhauls and Upgrades

Keeping up with a changing world is a challenge we embrace. Laws regarding the use of refrigerants continues to evolve, that should be our concern, not yours. Upgrading to environmentally friendly refrigerants is only small part of what we do to improve your bottom line while protecting the environment.
