1、Introduction

Increased urbanization, economic prosperity, cost of fuel, road congestion and environmental
issues are driving a revival in the mass transit market. These issues are driving the need for efficient
and effective mass transit systems, and the rail industry is faced with a challenge to provide a more
efficient way to transport people with higher reliability at a lower cost.

One significant domain in railway transportation is the train control system. The train control
systems required to address the needs of the global mass transit market cover a wide range from
basic line of sight signalling systems up to the unattended train operation system also called UTO.
The signalling and train control products are among the components that contribute most to the
enhanced performance of the railways. Over the last decade the railway industry has invested
significant research and development effort to improve the train control systems, taking advantage
of the technologies and innovations now available on the market.
Bombardier Transportation has invested significant efforts in streamlining the products,
technologies and capability; and has structured its signalling solutions in the most comprehensive,
cohesive and upgradeable product lines. The products have been organized into two main structures:
Bombardier* INTERFLO* for mainline solutions and Bombardier* CITYFLO* for urban needs.

The INTERFLO system offers complete mainline solutions individually tailored to the
customer’s need, encompassing integrated operations control systems and computerized
interlocking systems, as well as automatic train protection and wayside equipment.

The CITYFLO system provides complete urban railway solutions for all types of mass transit
such as trams, light rail vehicles and metros to suit various operating modes and customer’s need.
These include cab signalling, semi-automatic train operation, driverless and unattended train
operation. The systems can be expanded to the customer’s growing requirements and thus meet the
operational demands for the entire life of the system.

The various solutions and applications are summarized below.

INTERFLO 50 GPS-based train location and information system
INTERFLO 100 Conventional regional line system
INTERFLO 150 Radio-based regional / industrial line, including ERTMS based system
