Case studies
We never left the root cause.
Traila began at the wheel-rail contact and stayed there. The origin is active steering; the work continues in the vehicles of tomorrow.
Operator work
Rail-profile wear versus simulation, Weinberg-Leonhardstrasse
VBZ shared years of rail-profile wear data for a tight Zurich curve. Traila's own simulation reproduced the same pattern, curve section by curve section.
Top-of-rail friction, measured across three Zurich sections
One August day, three sections, one portable tribometer: what the friction coefficient actually does, lubricated and not.
Test-vehicle programme
TX4: active steering in the real world
The TX4, a modified Tram 2000 tram, is how Traila proved it.

Research and data
Network Curve Atlas
The Network Curve Atlas models curve-squeal risk from track geometry and market data. It is modelled, not measured, and not a claim about any named network. It reads the shape of a network to show where curves are most likely to squeal.
Next-generation vehicles
The work continues in a next-generation vehicle programme with academic and industry partners, taking the root cause into the vehicles of tomorrow. More to be announced.
Our scientific papers
Traila is at the forefront of scientific innovation. Our achievements include groundbreaking proprietary algorithms that significantly improve the precision and efficiency of rail vehicle manoeuvrability, advances in control system theory, new approaches to rail simulation, tribology, machine learning, and artificial intelligence, as well as several patents for mechanical solutions in the rail industry.
