Wayside communications package

Efficient and reliable connectivity

Siemens wayside products are used throughout the rail industry to provide critical track occupancy detection and communications. Our cost-effective, robust solutions connect train operations to back-office management. A modular architecture allows for flexible as well as simple installation and maintenance.
Communications modules

For reliable communications between office and field locations

The Siemens AB switch (53434 series) is normally used in conjunction with two of our 9-port wayside communications controllers/field protocol devices (WCC/FPDs) (53401 series) to provide redundant communication with code lines. The switch and the two connected WCC/FPD units communicate via an Echelon (LonTalk) LAN. The switch constantly checks the health of the WCC/FPDs and, if any problem is detected with the primary unit, the AB switch automatically transfers all lines to the backup unit. All the modules can be easily mounted on standard relay racks, instrument house backboards, or even shelf mounted.
