Who we are

Swiss specialists in one physical system.

Traila are wheel-rail interface specialists. The founders' research into the wheel-rail contact and vehicle dynamics reaches back to the mid-1990s, across rotating-flange wheels, adaptive conicity and active-steering methods, all aimed at the same root cause: what happens where the wheel meets the rail.

Founded 2018, Regensdorf, Zurich.

Interested in joining Traila's mission?

Prof. Oldrich Polach with a Traila engineer in front of a wheel-rail contact poster. — Visit by Prof. Polach.

Professor Oldrich Polach is a world-renowned expert in railway vehicle design, testing and vehicle dynamics simulation, and a pioneer in wheel-rail contact modelling. Building on an extensive body of experimental and numerical work on wheel-rail adhesion, he developed the Polach formulation (or Polach method): the algorithm widely used for the fast calculation of the tangential creep forces and adhesion generated at the wheel-rail interface.

Partners

One provider answers for the quiet. Two specialists earn it.

Silencing the interface takes accurate sensing, proven chemistry, and the intelligence to aim both: Traila Tuner, the onboard monitoring and friction-control unit, senses the contact, and Traila SoundTrack, the fleet platform, reads it across the fleet. The sensing hardware and the conditioning pedigree come from specialists with decades on exactly those parts. The operator deals with one provider, accountable for the quiet.
