“…With the help of simulation tools, we can model trains running under the planned infrastructure to test the feasibility of the operations timetable. However, most simulation work addresses operations improvements for freight trains [6,11] and passenger trains [9,12] services but not for APMs at airports. As the APM is becoming a key transport technology, especially for large airports, it is worth using a simulation to investigate the operations to ensure service viability of APM driverless operations.…”

“…In addition, rolling stock information such as tractive force, numbers of engines, braking characteristics influenced train movements and line capacity in this case [19]. In order to increase the line capacity, different schemes can be used, such as reducing the dwell time, rearranging the station locations, adjusting the train speed, or installing additional signaling equipment [11,22]. However, adjusting the dwell time affects passengers directly in terms of service satisfaction and may cause density problems on the station platform if passengers cannot board the train.…”

For the first time in Thailand, an Automated People Mover (APM) has been implemented at Suvarnabhumi Airport. The APM uses the guided way concept similar to metro rail operations, but with driverless trains on rubber wheels. As the APM becomes a key transport technology especially for large airports, it is worth investigating the operations to ensure service viability of driverless APM operations. This research uses a microscopic simulation model to evaluate the feasibility of APM operations and timetables in accordance with capacity requirements. The APM headway is often limited by turnback operations using a single track at the entry-exit of the station. To increase line capacity, headway should be decreased or train capacity should be increased and the itinerary needs to be reevaluated. For an airport APM, the headway should only be decreased within certain limits to achieve the benefits of higher network capacity without compromising passenger travelling time. Increasing train capacity using coupled trains can accommodate more passengers on each trip, but the number of trains available should be considered. The simulation result reveals the critical factors that contribute to improve network capacity and offers guidance for the complex APM operations in the future.

“…However, these only compare the railway line capacity indicators before and after the modernisation of the railway infrastructure. The actual process of traffic optimization on these lines is not described anywhere and the possibilities of train operation simulation are only described briefly [13]. It is only the demographic factors influencing the demand for public transport that are mostly taken into account [14].…”

This paper presents a pricing model of railway infrastructure capacity allocation functioning as a regulatory measure while fulfilling the regulatory requirements on railway infrastructure capacity allocation. The prices of railway infrastructure capacity allocation will be modelled with regard to all economically justifiable costs of railway infrastructure capacity allocation. The structure of model has been developed as a set of calculation sheets in Microsoft Excel. The recommended prices for railway capacity have been found by simulation of a set of variants and the recommendation is done for different operational conditions in an individual way. It analyses different products offered by the railway infrastructure capacity allocator both in the annual working timetable mode, and in the individual ad hoc mode. The aim of the proposed model is to motivate not only railway undertakings, but also the railway infrastructure capacity allocator to submit requests for railway infrastructure capacity in the annual working timetable mode rather than in the individual ad hoc mode. The total price is then verified to the cost of railway infrastructure capacity allocation. This process then ensures the regulation of the demand of railway undertakings on the given route and can influence the decision about the use of the product offered.

“…There are some articles which solve this problem from the capacity point of view [8][9][10][11], the economic point of view [12,13], or the strategic point of view [14,15]. But none of those articles addresses the possibility of simulating those regional lines with simplified train operational control in a simulation tool.…”

Simulation of Railway Lines with a Simplified Interlocking System

This paper deals with railway lines with low traffic intensity where trains are operated under simplified conditions. Those conditions are stated in a regulation, and there is no interlocking system on the line. The whole railway operation is organized according to a regulation in cooperation with the train crew. For the calculation of the throughput, we can use analytic or simulation methods. On those lines there is a big problem with the common working methods because of special circumstances on each line, which are influencing the technological times and reliability of the calculation. The simplified conditions are the transforming of regular interlocking systems on the administrative level. Therefore, it is very complicated to use a common simulation model. Most of the simulation tools are not able to work with it. The motivation of this paper is to prove that modern simulation tools are usable for that specific condition as well. The simulation model was built in SW OpenTrack which is able to modify its functions to figure out each technological action to ensure the correct function of the model. This functionality is described in the paper in general and implemented on a case study.
