In the area of passenger railway transport, the concept of train units with drive distributed along the entire train has prevailed during recent decades over the former train concept of locomotive and connected wagons. Therefore a typical Bonatrans delivery for a passenger transport project includes power driving and non-driving wheelsets and parts.
Driving wheelsets - Standard wheelsets - Wheels, axles
Wheelsets and their parts for locomotives require high strength and fatigue resistance, since these wheelsets transmit large forces from the locomotive driving unit at high speeds, and are also exposed to high axle loading. Bonatrans designs and manufactures wheelsets meeting these requirements while keeping optimized weight and high production accuracy. Bonatrans supplies these wheelsets to the majority of the worldâ€™s leading manufacturers of locomotives on several continents.

Bonatrans products for urban mass transport are characterized by their driving comfort, safety and reduced environmental impact, especially in the area of noise reduction. Bonatrans produces applications both tramways, for suburban transport and for subways.

Railway freight transport is given great attention in Europe due to its lower environmental impact compared with road transport, and its significance should grow in the future.
Wheelsets for freight transport represent a significant segment of products developed and supplied by Bonatrans which is the biggest manufacturer of freight wheelsets in Europe.
Bonatrans has developed and supplies a number of wheelsets optimized for the demanding needs of existing and future railway transport, i.e. wheelsets for high axle loading, with increased safety â€“ resistance to deformation and reduced stress and longer service life, i.e. with low life cycle costs.
Bonatrans wheelsets and wheels are certified by a number of European railways and are gradually replacing obsolete wheelset types.
Besides new wheelsets, Bonatrans also supplies a complete range of parts for repairs and servicing wheelsets.

Railway transport is known to have lower environmental impact compared with road transport. Nevertheless, there are also effects on the environment that have to be solved. This includes especially the issue of noise, which is paid great attention.
One of four primary rolling stock noise sources is the noise that is generated during rolling of wheel on the rail. And this is exactly the noise source the Bonatrans research department focuses on. These activities lead to implementation of several wheel noise and vibration (generated by the wheel rolling) absorbing systems.
