A heavy haul train and car dumper model was created to analyse train longitudinal dynamics during dumping. Influence of such factors as performance curve of draft gears, total free slack in couplers, operating mode of train positioner and braking of last two cars of train on the in-train forces was considered.

Algorithms for simulation of trains as coupled detailed spatial and simplified one-dimensional models of rail vehicles are considered. Such an approach to train dynamics allows evaluation of in-train forces and their influence on dynamic characteristics related, e.g. to the safety problems or ride comfort. Initially, the method has been developed for the analysis of derailment accidents and further it has been implemented as a mechanical solver in six-degrees-of-freedom train simulator TRENSIM, which features are discussed in the paper. An algorithm for parallelisation on multi-core processors for the simulation of rail vehicles and trains is presented.

Longitudinal train dynamics (LTD) simulations have been playing an instrumental role in the development of larger trains, especially freight trains. LTD simulators have been reported from all around the world, but without standards or standard questions to assess the correct implementation of LTD analysis and the state of LTD studies. Under this situation, the Centre for Railway Engineering initiated the International Benchmarking of Longitudinal Train Dynamics Simulators. Eight teams involving 10 institutions from five countries across three continents have participated in the benchmark and submitted their results. This paper describes the benchmarking questions so other researchers will be able to repeat the simulations in the future and benchmark their programs against the current participating software. The question information includes train configurations and characteristics of the wagon connection system, locomotive traction and dynamic brake characteristics, resistance formula, track data, train driving controls and output requirements. The question information will also enable researchers to replicate the benchmark by providing relevant formulas, data sheets, figures and descriptions.
