Engineers from EC Engineering in Krakow have designed powered and rolling bogies for high-speed trains

EC Engineering is one of the world’s leading providers of design services for the railway sector.

In addition to its design activities, the company also engages in the production of tools and components for rail vehicles in its two manufacturing plants. The first is located in Podłęże near Krakow, and the second is in Mielec.

Recently, the company completed a project for the design of powered and rolling bogies for one of the Asian high-speed train manufacturers. Due to the client’s policy, the specific details of the recipient cannot be disclosed.

Engineers from Krakow were tasked with developing the construction and conducting simulation analyses of the powered and rolling bogies designed for passenger trains that will operate at speeds of up to 400 km/h.

The company expected the designers to incorporate technological solutions and materials that would allow achieving a low weight of the bogies and ensuring excellent passenger comfort. An essential aspect of the project was also to reduce the noise level during travel at speeds exceeding 200 km/h.

Materials and components had to be adapted to work in low temperatures (down to -40°C) and in snowy conditions, which often lead to the icing of the undercarriage and bogie elements.

This required the use of active de-icing systems, unconventional design solutions, and the implementation of additional sensor systems responsible for continuous monitoring of signals in case of damage.

Currently, the bogie project is complete, and the production of a prototype is planned for the next year.
