In the railway operations laboratory (EBL), the individual levels of railway operations (planning, management, safety and external operations) and their relationships are clarified. The person being instructed can take over different functions (e.g. dispatcher, service manager etc.) in order to be able to understand the operational relationships from different angles through personal intervention. Here, the different signal box technologies are of particular importance. One can most clearly understand the safety philosophy when one looks at the older designs (particularly the mechanical designs), however the trainees can familiarize themselves with the basis of the electronic signal box with the user interface of the future.
modernization of the plant in the years 2009/2010, the second highest
level, the operational control can now be investigated in EBL: The
installation of the control system ILTIS of Siemens Switzerland AG
means that almost all operating locations can be controlled by signal
boxes. The infrastructure has been extended to give an eight track
station Testadt which has a passenger and a freight station part.
The former terminal stations Pewald and Iggswil have now been
complemented by another station head and are connected to an eight
track staging station Utal. Further, vehicle control is implemented
and this provides the features of realistic vehicle dynamics
dependent on traction and train mass. Thus, for example, the
incorrect operation of the signal box by the operator would be
directly and vividly illustrated by the resulting delays.
The following three project partners are responsible for the modernization and operation oft he facility:
In addition, the support of the following partners was won for the renovation:
The entire facility has an area of approximately 50m2 and includes 600m track and 7 stations. The track topology is shown in the schematic. In practice, the trains always make at least one circuit of the entire track before they go to the next station. Thus, the travel times between individual stations are artificially extended to simulate realistic conditions when operating in timetable mode.
As part of the command and control technology, all major signal box designs can be mapped: From the mechanical signal box (Iggswil) from the early years of railway safety engineering through the so-called "switch works" (Zetthausen) that embodies the collection of electrical impulses from the early 20th century, to ILTIS remote control technology which is now widespread in Switzerland, the EBL offers authentic workstations. The common relay technology from many decades is based on the Domino signal box design represented by (Do 67 - Ypslikon and Do 69 - Pewald) . The relay station Ypsilkon is based on original technology, which is located in a separate room next door, while due to the new modifications and extensions to the station Pewald, this is now controlled on the basis of SPS.
