Y25 freight car bogie models properties analysis by means of computer simulations
MATEC Web of Conferences, 2018 The article deals with the results of the simulation analysis of a railway wagon bogie model. We analysed four freight wagon bogie variants for its dynamics properties research. The bogie models correspond in general to the Y25 bogie concept.

Dynamic Responses of the Metro Train’s Bogie Frames: Field Tests and Data Analysis
Shock and Vibration, 2020 This paper focuses on the dynamic characteristics of the metro train’s bogie frames based on the field test data. The acceleration signals of both motor bogie frame and trailer bogie frame of a standard B-type metro train were measured.

International Journal for Research in Applied Science and Engineering Technology, 2022 Abstract: The Rocker-Bogie Mobility System was design to be used at slow speeds. It is capable of overcoming obstacles that are on the order of the size of the wheels. However, when surmounting a sizable obstacle, the vehicle motion effectively stops while the front wheel climbs the obstacle.

Twin disc assessment of wheel/rail adhesion [PDF]
, 2008 Loss of adhesion between a railway wheel and the track has implications for both braking and traction. Poor adhesion in braking is a safety issue as it leads to extended stopping distances. In traction, it is a performance issue as it may lead to reduced
