The Y25Lsi(f) is a modified version of the Y25 standard freight wagon bogie equipped with an integrated pneumatic brake system. All the
components required to generate the necessary braking force (i.e. the brake cylinder, brake linkage and slack adjuster) are installed inside
the bogie. The Y25Lsi(f) can be fitted with a ground-operated parking brake. Alternatively, the screw spindle of the handbrake mounted on
the bogie can be operated from the platform via an articulated shaft. The bogie is extremely reliable and TSI-WAG certified.
