Bogies Y25
Y25Lssi(f)-D
Connecting dimensions and properties of the headstock-free bogie are identical with the standard Y25Ls1-K bogie. Removal of the headstock preserved similar strength and running characteristics, but it also caused lower weight of the frame and the bogie dimensions are minimized. Installation of the disc brake into the bogie causes reduction of wheel wear and noise.
