The second part of the paper continues a discussion on the topic of parallel computations in railway dynamics. The algorithms described in the first part of the paper are applied to parallel simulation on computers with multicore processors of six different models of rail vehicles and trains with the number of degrees of freedom from about one hundred to more than 20 thousands. A considerable simulation speedup is reported. In addition, an example of evaluation of wheel profile wear on multicore processors and comparison of different approaches to multi-variant computations are considered.
