With projects around the world, Bombardier Rail Control Solutions has a wealth of experience in delivering high-tech systems in challenging environments and with minimal impact on ongoing operations.
The CITYFLO 150 mass transit rail control solution provides modular rail control technology for light rail and tram-based systems, typically manually operated. The solution supports on-street and segregated driving, and integrates signalling and auxiliary systems.
The CITYFLO 150 solution provides consistent performance in city and commuter rail systems where, speciﬁcally with respect to light rail operations, superior service is achieved through traffic prioritization, system regulation, point calling and passenger information.
Suitable for tram-based systems where manual train operation is typical, the driver operates the train/tram using wayside signals with the option on segregated sections of using a simple ATP system to safeguard train operation.
Applying its global experience, Bombardier Transportation has developed a standard off-the-shelf solution to meet today’s light rail requirements.

CITYFLO 250 is a balise-based system with onboard automatic train protection (ATP) displayed in the driver's cab. CITYFLO 250 is designed primarily for light rapid transit (LRT) or metro applications running on segregated or non-segregated tracks.
The EBI Lock computer-based interlocking (CBI) system detects trains through the track circuits, controls the EBI Switch point machines, the EBI Light signals and any EBI Gate level crossings within the solution. The interlocking also gives movement authorities to the onboard ATP. EBI Cab onboard equipment ensures that the train does not exceed permitted speeds or pass beyond the end of a movement authority. This enables onboard ATP to use distance-to-go supervision of the train’s movements.
Compared with a speed code system, EBI Cab onboard distance-to-go supervision provides higher traffic capacity and increased passenger comfort. This is due to shorter headways between trains, faster approach to line terminals and a smooth braking curve that is either on or stop. All indications to the driver are given via the in-cab display.
The CITYFLO 250 system uses the EBI Screen control room which gives the metro operator total overview and control of the traffic and the transit system.

The CITYFLO 350 solution is a system with onboard automatic train protection (ATP) and automatic driving through an automatic train operation (ATO) with the ATP information and ATO status displayed in the driver's cab. The track-to-train communication is achieved via audio frequency track circuits. The system is designed primarily for metro applications where only limited action is required from the train driver, such as opening and closing doors, and is used for trains running on segregated tracks.
The CITYFLO 350 solution uses EBI Lock computer-based interlocking which detects trains through the track circuits and controls the EBI Switch point machines and any EBI Light signals within the system. EBI Track allows speed values, distances, gradients and other information to be transmitted. This enables onboard ATP to use distance-to-go supervision of train movements. The ATP also ensures that the train does not exceed permitted speeds nor pass beyond the end of a movement authority.
The EBI Drive ATO system, part of the onboard equipment sub-system, fully exploits the capacity of the metro system as the train travels between two stations at a safe distance from other trains. The driver’s actions can be limited to opening and closing the doors of the train.
The CITYFLO 350 solution uses the EBI Screen traffic-management system, providing the decision-makers responsible for traffic administration with immediate access to up-to-date information.

CITYFLO 450 is a communication-based train control (CBTC) virtual block system designed for metros with drivers. The system is used for virtual block semi-automatic running of trains (STO) on segregated tracks and has the potential for upgrading to a driverless system.
Inexpensive to install, the CITYFLO 450 solution eliminates wayside equipment due to its simple, reliable, contactless train-to-wayside communications system, permitting shorter and more consistent headways. The CITYFLO 450 system is based on the successful CITYFLO 350 platform. The EBI Cab onboard ATP ensures that the train does not exceed permitted speeds or pass beyond the end of a movement authority.
The EBI Drive Semi-automatic Train Operation (ATO) system, which is part of the EBI Cab onboard equipment, fully optimizes the capacity of the system as the train proceeds along the line at a safe distance from other trains. The ATO ensures smooth braking and acceleration, resulting in energy savings and less wear and tear. The ATO system provides precision stopping at platforms with high accuracy and automatic door operation. In semi-automatic mode, an operator may initiate station departures and close doors. CITYFLO 450 uses the EBI Screen control room to give the metro operator total overview and control of the traffic.
Since train-to-wayside communication (TWC) is provided via two-way radio, the CITYFLO 450 system can be used as an overlay radio-based train control system to upgrade existing ﬁxed-block systems.
The CITYFLO 550 solution is a track circuit-based system for driverless (DTO) or unattended (UTO) train operations, designed for automated people movers (APM) and automatic operation for mass transit systems.

The ATO system fully exploits the potential capacity of the system as the train travels at a safe distance from other trains. It reduces energy consumption and wear on the track and vehicles. The ATO system provides precision stopping at platforms, automatic door operation and automatic turnback at terminals.
CITYFLO 650’s driverless moving block technology provides ﬂexible headways as standard with the capability to change headways dynamically. System updates can be easily managed and safely distributed remotely to trains anywhere in the CBTC network, critical for update of large ﬂeets.

The EBI Screen control room is a traffic management system for efficient and economic management of mass transit networks. The system is ﬂexible with an open interface to peripherals such as passenger information, ticketing machines, power supplies and SCADA giving the operator total management of the traffic.
The EBI Lock CBI system ensures maximum availability and safety by using redundant interlocking computers. The interlocking system is of a modular design for high ﬂexibility, and is easy to adapt to different signalling principles. The interlocking system is equipped with an advanced function for diagnostics and self-tests, meaning a fault can be quickly discovered and identiﬁed. Diagnostics information is sent to traffic management service personnel via a PC-based terminal.
The EBI Com Radio Block Centre (RBC) converts train positions sent by radio into positions of the trains on a track plan that is then presented to the interlocking system. Information about train routes is then sent to the EBI Com RBC, converted into movement authorities and sent out to the individual trains.
The EBI Cab onboard equipment ensures that train movements are carried out safely in accordance with the movement authorities. The train speed is continuously monitored by the system and if necessary, the EBI Cab system initiates braking to keep the train at a safe speed.
ATP utilizes EBI Link balises that provide either ﬁxed or variable data from track to train. The balise is activated by an antenna mounted under a passing train, avoiding the need for a dedicated power supply. Only the controlled balises (with variable data) need a cable connection to a control unit.
