The bogie Y33Lsi-Fsp-265 kW is designed, based on the UIC-standard bogie Y33, using the experiences with the compact frame of the
ELH-bogie Y25Lsi-C for the use in high-powered on-track machines. With the application of water-cooled asynchronous traction motors
and the single-sided push brake with composite brake blocks a very compact design was found. The suspension is optimized for the used
load range. The bogie design is modular, so it can be fitted with different additional devices such as train control systems, sanding devices,
suspension blocking systems and so on as well as with different drive and brake components.
