KOAX SR Interface for Elektra level crossing
In order to replace traditional TM-relay interface for Elektra-MÁV station level crossing, a new interface has been developed by Axon 6M Kft. This interface is based on Hengstler relays. Together with this development, new LED lamps are built in the traditional red and white warning optics. Each lamp (light) is checked by a 2002 microcontroller system. This paper introduces the development of the
whole KOAX-SR system, focusing on application of new LED technology and safety aspects of lamp checking.

Electric supply system simulator of Axon 6M Ltd.
The article gives an inside look at the core modules of the
Electric supply system simulator. The simulation processes are based on 3 algorithms – a linear, a non-linear and a
dynamic method. On this basis, the software offers a variety of features specialized for the needs of the MAV.

Simulating train traffic and the electric supply system of the Budapest-Győr train line
The goal of the project was to find all bottlenecks of the current infrastructure due to the expected increase of international train traffic on the Budapest-Gyõr line. This paper discusses the applied methods and software tools. Among others, a timetable editor with enhanced conflict detection and a complex simulator for train traffic and electric supply system are presented.

Test tool for simulation of track occupancy
Universal test tool for station interlocking systems developed by Axon
6m ltd. which makes on-site tests
easier. It is capable to simulate the
whole “railway-environment”
including all in Hungary usual railway elements. Rail-occupations due
to train-movements can be tested by
single clicks on every track segments
or by an automatism that lets the
“train” move realistically from start
signal to target using its physical
parameters (length, weight, PS of
engine, etc.). The system is networkenabled: it can test up to 10 connected station interlocking systems at the same time.
