Reliable models of passengers, seats and carbody are essential in order to predict ride comfort of rail vehicles. This paper extends previously presented models of passenger-carbody interaction to include vertical seating dynamics. The proposed basic model is based on experimental modal analysis of a rail vehicle with and without passengers. The notions of "human-body normalized apparent mass" and "seat transmissibility" are fundamental in the modelling. The possibility of using reduced and approximate models is also discussed in the paper. The proposed models are easy to use and implemented in commercial rail vehicle software.
