The WMS-2000 series of Wayside Messaging Servers from Lilee Systems provides an interoperable communications gateway platform for Positive Train Control systems. The primary function of the WMS-2000 is to run the ITC Messaging System between local Wayside Interface Units (WIUs) and the communications network in an Interoperable Train Control architecture. It features an integrated IP router for managing seamless communications between 220 MHz WiFi, cellular, and other wired and wireless mediums. An internal 10/100/1000 Mbps Ethernet switch allows multiple WIUs to be interconnected at a wayside location, eliminating the need for an external switch.
Internal 3G cell and WiFi options are also available to add additional flexibility to the PTC installation. These wireless links may be used as an alternate path to a 220 Mhz link, or used in combination with a 220 Mhz radio to provide a remote link used for diagnostic and software updates. The WMS-2000 may also be used in conjunction with the Wayside Status Relay Service (WSRS) for a 220 Mhz base station approach to a communications architecture. Leveraging the internal IP router, the WMS-2000 uses policy-based metrics for best path selection between the field, locomotive, and office segments.
In addition to the ITC Messaging System, the WMS-2000 also provides a host of industry standard protocols for deployment in a modern IP network such SSH, SNMP, DHCP, and AMQP. In addition to the ITC Messaging System, the WMS-2000 supports traditional train control protocols in order to consolidate on a single messaging protocol across the train control network. This offers railways the option to streamline their operations and lower the number of devices required to support the train control network.
An optional internal GPS supports Network Time Protocol (NTP) and GIS-based mapping tools. A Site Specific Module (SSM) can also be used to quickly upload new configuration files, download local logs, or provide other functions useful to the rail operations.
The WMS-2000 provides dedicated console and Ethernet diagnostic ports for rapid resolution of trouble while on site. For remote diagnostics, IP tunneling, SNMP, and internet browser connections are supported. Through the use of the optional IP-KVM interface, users can provide software application upgrades remotely without the need for on-site service visits, thus further reducing the overall cost of maintenance.
The WMS-2000 series is compliant with the specifications set forth by the Interoperable Train Control committee for standalone Wayside Messaging Servers (AAR Standard S-9202A).
