Product Overview
The SF 500 bogies represent a significant advancement over the SGP 400 series, with 950 units already in operation on the Deutsche Bahn AG's ICE2 trains. These bogies are engineered for electric railcar trains and modern high-speed rail applications, delivering superior ride quality.

Siemens Mobility has received substantial orders for the SF 500, totaling over 6500 units from operators including Deutsche Bahn AG, Netherlands Railways, and RENFE, among others.
Design and Modularity
The SF 500 bogie features a modular design, allowing it to be configured as either a motor bogie or a trailer bogie. It can be fitted beneath carbodies with or without a bolster, offering flexibility in application. The use of lightweight components results in a significantly lower bogie weight compared to similar models.
Extensive analysis of running characteristics has informed the design, ensuring optimal stability, ride quality, and excellent axle guidance. The bogie utilizes a proven link system for axle guidance, with laminated guides available as an alternative. The bogie frame is constructed as a flexible, open H-Frame.
Suspension and Traction Systems
Exceptional ride quality is achieved through the secondary suspension system, which incorporates a high-tech air suspension system and a large air volume. Key components like the pivot, yoke, and traction rods are based on proven designs, similar to those used in the ICE2 concept.
Torque transmission from the lateral traction motor is managed by a partially suspended, low-noise gear system per axle, coupled with a spiral-toothed coupling. The bogie traction motors are flexibly suspended within the bogie structure via a dedicated motor support and an innovative laminated spring damper system.
Suspension design prioritizes running stability and acoustic performance. Redundant-type hydraulic yaw dampers are integrated to stabilize running behavior at high speeds.
Braking Systems
Trailer bogies are equipped with a mechanical disc brake system, featuring 2, 3, or 4 discs per axle, along with a non-wear eddy-current brake. Motor bogies utilize wheel disc brakes.
