According to Men MICRO, for track-laying and track maintenance machinery, heavy stress by vibrations and shock during automatic ballasting or tamping and the wide temperature range during day and night operation need to be considered.

At track laying, machine may weigh up to 50 tons and can be more than 20 metres long. The majority of maintenance works must be done during night operation breaks.

Deviations of the track geometry are allowed only within a few millimetres in all three dimensions. Thus, the electronic equipment for controlling and driving the maintenance trains and for measuring and visualising the track geometry needs to be highly rugged.

In this application, a computer-aided tamping system based on 3U CompactPCI is used to do the calculation and visualisation of the track geometry with subsequent control of the track-laying process itself.

The same system can be used to control the track geometry during the following periodic maintenance drives.

While the calculation and control is done in real-time, based on a PowerPC single-board computer under embedded Linux, the graphical user interface is based on a separate Pentium III CPU card under Windows.

A second measuring system, 3U VMEbus can be used optionally on the same track-laying vehicles. It consists of several computer nodes that communicate over industrial Ethernet.

The 3U VMEbus system is based on a PowerPC single-board computer that calculates the absolute track error from a multitude of data. It controls the track tamping machine through a combination of digital and analog I/O M-ModulesT, which are optically isolated.
