Plasser & Theurer is headquartered in Austria, and is the only manufacturer in the world that offers a complete range of machines for the laying and maintenance of railway tracks. The company also has a location in Chesapeake, VA, operating under Plasser American, which manufactures and services railroad equipment.  Back in 2016 a company that was assisting Plasser with building a truck during product development, reached out to Cotta for a custom transfer case that would be used in a new mobile rail welding truck.  Cotta’s engineering team worked closely with the customer, and offered a solution that met the weight limitations and all other requirements.

David White, contracting/service rep for Plasser American, stated “The Cotta gearbox has been working solid.  The past 2-3 months we have been running the unit even harder 6-7 days a week, sometimes double shifts with 16-20 hours/day.”  David expressed how happy they have been with the Cotta transfer case, and that they have had no issues with the unit.  He further stated, “Whenever we’ve had regular maintenance on the unit and needed parts, Cotta’s service was always great and we never had any issues getting parts in a timely manner.”

Plasser succeeded in integrating their top technology for rail welding into a truck vehicle that doesn’t exceed Federal Bridge Law weight limits. Plasser is breaking through an old market with this product line.
