Dispatch Center

Dispatch Center is equipped with a computer system that displays the location of all trams along with deviations from the timetable on a digital map of the city. The dispatcher has the ability to establish audio connection to any tram or group of trams (e.g. trams driving on specific line, or in a designated area), as well as send text messages which are displayed on a driver's panel. Read more...


Traffic Control Center

SNRT2000 is managed by central server that runs dedicated software. It is based on a relational database and is divided into components that use dedicated network protocol. The components are based on the APP-COMMON backbone, using PRO-PAN transport environment. Such software design allows fine-tuning of all aspects of the system according to Warsaw Tramways requirements, and implementing necessary updates without the risk of system failure. Reliability is futher increased through the use of redundant components. Read more...


Communication Center

The Communication Center includes Data Transmission Center (data transmission between vehicles and Dispatch Center) and Voice Communication Center (audio transmission between the dispatcher and drivers). Communication center and radio base station are located on the building's roof in the center of Warsaw. Read more...


Depot Systems

SNRT2000 provides connectivity with four tramway depots, where WLAN networks were installed in order to automatically exchange data between on-board computers and local servers. Read more...


Vehicle Equipment

Each of the 500+ trams is equipped with a set of mobile equipment (Vehicular Units) used for data and voice communications between vehicles and Dispatch Center. Each set includes on-board computer, radio, duplexer, isolated voltage converter, integrated driver's panel with a microphone, integrated railway certified antenna and additional modules such as GSM modem, GPS receiver, traffic light priority transmitter or WLAN card.

Each set of Vehicular Units includes Integrated Driver's Panel ZPM200 (pol. Zintegrowany Pulpit Motorniczego), which is used for voice communication, text messaging and scheduled timetable realization by displaying deviations to the driver. Read more...


Traffic Light Priority Transmitter

Tramways are equipped with TX-U-100 transmitter that allows faster ride through intersection by sending radio messages to traffic light controller. Read more...


SNRT2000 equipment is certified according to PN-EN 50155 and PN-EN 50121-3-2 standards.
