In order to improve its position in the transport market railway, as a complex system, it has to fulfill a number of objectives such as increased capacity and asset utilization, improved reliability and safety, higher customer service levels, better energy efficiency and fewer emissions, along with increased economic viability and profits. Some of these objectives call for the implementation of maximum values, while some of them require minimum values. Additionally, some can be expressed quantitatively, while some, for example, customer service, can be described qualitatively through a descriptive scale of points. The application of MCDM in railway engineering can play a significant role. Therefore, the major objective of this chapter is the review of the application of MCDM methods in railway engineering. As one of the means in achieving the objectives of railways and above all the utilization of capacity are Train Control Information Systems (TCIS). Based on that, the aim of this chapter is the evaluation of the efficiency of TCIS in the improvement of railway capacity utilization through defined technical-technological indicators. The non-radial Data Envelopment Analysis (DEA) model for the evaluation of TCIS efficiency in improvement of utilization of railway capacity using the selected indicators is proposed. The proposed non-radial DEA model for TCIS efficiency evaluation in using railway capacity could be applied to an overall network or for separate parts of railway lines.

“…The output of simulation modeling, such as the travel time, can be displayed in the form of a graph or a table, which is easy to present and shows the overall result [17]. Several reseachers such as Keiji et al [18], Ljubaj et al [19], Pouryousef and Lautala [20] have used simulation modeling to address the operational challenges. PitaIänen and Capek [21], Botte and D'Acierno [22] used rail simulation modeling to show the effects of redesigning the track network, signaling, and turning points to improve track capacity.…”

Operational Challenges of the Bangkok Airport Rail Link

The airport rail link (ARL) was launched in 2010 as a premium rail transit service between the inner city of Bangkok and the airport. In 2014, the express service was canceled due to its unpopularity and transformed into the commuter service. In 2017, the new extended service concept was introduced under the three airport links project. Under this new concept, both ARL and high-speed trains will run on the city line section between Don Mueang and Suvarnabhumi Airports. This paper focuses on the use of a microsimulation model to identify the challenge of mixed-service operations, with regular and express trains running on the city line section. The simulation model allows investigation of hypothetical situations and construction of feasible timetables. The model can identify sections where special attention is needed, such as speed reductions, extended dwell times, or delayed departures. During the peak hour, the results suggest that the regular ARL should run with a 10-min headway and the highspeed one line with a 20-min headway, as an alternative solution. This results in fewer train numbers and less additional running time. Simulations indicate that the highspeed train is not efficient, as it consumes 2-3 times higher energy, while offering little time saving compared with the ARL city train. In addition, the Suvarnabhumi Airport extension track layout needs to be carefully considered, since the Suvarnabhumi Station area is a bottleneck liable to disruption.

“…The input data for the simulation model is data on infrastructure, vehicles and timetables. The software has been designed in a way that it allows for creating a model respecting the specificities of different railway systems, including mainly the different transport and signal regulations and the particular characteristics of train safety devices [6][7][8].…”

“…The use of simulation modelling opens up new possibilities in determining railway line capacity. Simulation allows for checking the usable capacity of any part of railway infrastructure taking into account local specificities and traffic characteristics [6]. However unlike in analytical methods, the output of simulation is not a specific value describing the usable capacity of the line.…”

The use of simulation modelling for determining the capacity of railway lines in the Czech conditions

AbstractSimulation modelling is one way to determine the capacity of railway lines. The specialized software tool OpenTrack was used for simulation. The aim of this paper was to find out whether the OpenTrack simulation software can be used for the calculation of headway, and to compare the results with the methodology of the Railway Infrastructure Administration (SŽDC). Using the software tool, a detailed transport network model can be created including all its important characteristics. The simulation follows the movements and behaviour of trains with predefined parameters on the modelled railway line. OpenTrack allows for monitoring a range of parameters including not only train delays, train conflicts and train traffic flow, but also for instance train energy performance and headways. During the first stage of work with OpenTrack, a simulation model was created, not reflecting any existing infrastructure but including parameters typical of railway lines in the Czech Republic, such as the configuration of gridirons, length of station tracks, size of block sections, etc. This model was subsequently used for the simulation of type train set journeys, and a headway calculator was used for the calculation of headway values. These values were compared with the methodology used by the Railway Infrastructure Administration. The paper is concluded by the comparison of the above mentioned approaches.
