The CBTC Segment Dominates Owing to the Growing Need for Improved Communication across the Railway Transportation System

Based on technology type, the market is segmented into Automatic Train Protection System (ATP), Positive Train Control (PTC) system, Communication-Based Train Control (CBTC) system, Automatic Train Operation (ATO) system, and others.

 The Communication-Based Train Control (CBTC) system segment held the leading global Railway signalling system market share in 2022. CBTC is a railway signalling system that uses telecommunications between trains and track devices for infrastructure control and traffic management. The communication system used in railway signals has unique requirements largely dependent on the railway system's characteristics and performance. Therefore, it is necessary to understand the transportation system's factors and performance in detail and provide appropriate requirements for the communication system. Using the CBTC systems, the train's exact location can be obtained more precisely. Thus, railway traffic can be managed more effectively and safely.

Increasing investments in urban transportation, especially in the railway network, fuels the global demand for CBTC systems for effective railway traffic management. The increased number of passengers, the increasingly fierce competition among the operators, and higher expectations for safety and comfort are driving railway operators to replace or upgrade their rolling stock. Because of the high utilization rate of existing infrastructure, a modern signalling system is essential to improve network security and capacity.

For instance, Alstom seized a Mumbai Metro Railway Company Limited (MMRCL) contract to provide the CBTC Signalling system for Mumbai Metro Line 3. The contract is based on the rolling stock and power supply contract won for the same metro line earlier this year and is worth more than 100 million euros. Line 3 will be equipped with Urbalis 400, the latest generation of Communication-Based Train Control (CBTC) signalling technology. The contract includes platform screen doors, computer-based interlocking, centralized train supervision, unmanned train operation (UTO), mechanical and electrical supervisory control, and a data acquisition system (E&M SCADA).

By Application Analysis

Increasing Demand for Signalling Systems Inside the Station to Improve Rail Passenger Service will Boost the Market Growth

Based on the application, the market is segmented into inside-the-station and outside-the-station.

The inside-the-station segment accounts for the largest share of the global market. The signalling system is widely utilized inside the station as the station is the place where every train halts and departs. The trains' arrival and departure schedules depend entirely on the railway signalling system that sends accurate location of the other trains and occupancy of the railway tracks. In railways, the railway station and train operation's communication system is realized by the signal sent out by the wired media. After the train departed from the station, there was no communication between the running train and the station or the controller.

Nowadays, railways worldwide are installing optical fiber cables for communications between stations to send signals to the trains. Using fiber optic cables is not as easy to provide trackside communications as copper cables. Therefore, when communicating with drivers, guards, maintenance gangs, guards, etc., outside of the station limits, another transmission medium is required. This communication medium is wireless. With the increasing number of high-speed rail networks and the adoption of automated management systems, the demand for wireless sensor network-based systems will accelerate. Therefore, boosting the expansion of advanced technologies outside the station.
