This article discusses the reason for the suspension of railway traffic on the Jelenia Góra - Karpacz route. The possibility of reactivating the transport on this route was indicated. Based on the equation of the train movement, calculations of the theoretical travel were carried out, as a result of which the technical and total travel time were determined. A rational interval of train runs was determined and a timetable was proposed, taking into account relations going beyond Jelenia Góra. The article justifies the need to introduce supplementary connection operated by electric buses. The concept of reactivating traffic in this area should be supplemented with the construction of a P + R car park. The possibility of further development of the transport system in the discussed area was also proposed.

In training process of rail traffic manager (controller) using virtual reality technology, selection of activities among those assigned to a workplace and scenarios that should be taken in training is an important issue. The selection method that is based on performance variability of her/his activities has been proposed in the paper. This variability has been characterized by timing and precision. The traditional reliability and safety analysis methods are not sufficient when building the training program for traffic managers. In the paper the train controller work has been modelled using Functional Resonance Analysis Method (FRAM) that is system oriented approach. Scales of values of timing and precision that are train transport driven have been presented. They are different when comparing with typical timing and precision scales given in FRAM literature. In the paper the estimation of probabilities of occurring of values of timing and precision scales for these activities has been calculated as the mean from the values obtained by questionnaire done in traffic manager community or using Analytic Hierarchy Process (AHP) method. In FRAM with AHP approaches presented in literature, AHP pairwise comparison is executed using natural numbers and their reciprocals what is typical in AHP method. In our paper the AHP is used for estimating the probabilities, so in pairwise comparing the rational numbers are applied, because natural numbers and their reciprocals would limit the set of values of probabilities. The activities and scenarios that the training should be concentrated on are selected from those with the greatest variability.
