阿尔斯通推出全球首条采用ETCS-3系统的印度密鲁特地铁

徐纪康 提供素材

阿尔斯通在印度密鲁特地铁启用了全球首个基于LTE 4G网的ETCS-3级信号系统的地铁线路。该线路是德里—密鲁特区域快速走廊的一部分，该线路覆盖新建21公里地铁线路及26.5公里区域快速线路。

技术参数

核心创新在于：在4G无线网络上部署ETCS-3级信号系统。该系统架构通过列车自主上报定位信息与基于无线通信的行车管理，降低了对轨道电路等传统轨旁列车检测设备的依赖。区域快线与地铁列车均采用阿尔斯通的Adessia平台列车，列车设计时速135公里，最高运营时速120公里，为印度速度最快的城市地铁列车。

该技术在市场中的定位

在大运量城市轨道交通领域，全球主流标准是基于通信的列车控制系统（CBTC），而将ETCS-3系统应用于地铁，是一次重大突破。

阿尔斯通该系统直接对标西门子Trainguard MT、泰雷兹SelTrac等成熟CBTC产品。CBTC是地铁专用解决方案，而ETCS则是铁路互联互通标准；将其应用于地铁运营，体现了区域铁路与城市轨道网络融合的战略方向。

相较于依赖地面欧洲应答器进行位置更新的传统ETCS-2系统，ETCS-3大幅减少轨旁硬件，灵活性更高，全生命周期成本也可能更低。此次落地使阿尔斯通处在印度铁路信号市场升级的前沿，该市场正吸引ABB、Kernex与巴拉特重型电气合资公司等竞争对手大举投入。

将源自铁路的ETCS信号系统用于地铁线路，是推动全网互联互通的战略举措，也是印度国家铁路规划的长期目标。这一模式打破了城市轨道与区域铁路之间传统的技术壁垒，有望构建更高效、一体化的交通生态。

常见问题

问：密鲁特地铁为何堪称全球首创？

答：密鲁特地铁是全球首条正式投入商业运营、采用ETCS-3信号系统+LTE 4G的地铁系统。这类技术以往多用于铁路，而非高密度的城市轨道交通。

问：该项目是否属于更大交通网络的一部分？

答：是的。密鲁特地铁与那摩·巴拉特区域快速运输系统（RRTS）直接一体化衔接。整个项目由国家首都地区运输公司（NCRTC）管理，旨在连通德里及周边卫星城，缓解地面交通拥堵。

Alstom Launches World’s First ETCS Hybrid Level 3 Meerut Metro

In Brief: Alstom commissioned the world’s first metro service using ETCS Hybrid Level 3 signaling over an LTE 4G network on the 21 km Meerut Metro line in India, part of the newly completed sections of the Delhi-Meerut regional corridor.

MEERUT, INDIA – Alstom has announced the commercial commissioning of the final sections of the Namo Bharat regional rapid corridor and the launch of the integrated Meerut Metro service. The project introduces the first-ever implementation of ETCS Hybrid Level 3 signaling for a metro system, covering a new 21 km line and an additional 26.5 km of the regional route.

What Are the Technical Specifications?

The core innovation is the deployment of the European Train Control System (ETCS) Hybrid Level 3 over a Long-Term Evolution (LTE) 4G radio network. This system architecture reduces reliance on traditional trackside train detection equipment, such as track circuits, by leveraging train-reported positioning and radio-based communication for traffic management. The rolling stock for both the regional and metro services is from Alstom’s Adessia platform, designed in Hyderabad and manufactured at facilities in Savli and Maneja under the “Make in India” initiative. The trains have a design speed of 135 km/h and a maximum operating speed of 120 km/h, making them India’s fastest urban metro trains. The broader project scope includes significant civil infrastructure, such as roads, culverts, and a new four-lane bridge connecting Trans Ganga City with Kanpur City, under the coordination of the National Capital Region Transport Corporation (NCRTC).

Where Does This Technology Stand in the Market?

The deployment of ETCS Hybrid Level 3 for a metro system is a significant deviation from the global standard for high-capacity urban rail, which is Communications-Based Train Control (CBTC). Alstom’s system competes directly with established CBTC products like Siemens’ Trainguard MT and Thales’ SelTrac, which are widely used in metros worldwide for enabling high-frequency, moving-block operations. While CBTC is a dedicated metro solution, ETCS is an interoperable mainline standard; applying it to metro operations suggests a strategic push for seamless integration between regional and urban networks. Compared to conventional ETCS Level 2, which relies on physical Eurobalises for train position updates, Hybrid Level 3 offers greater flexibility and potentially lower lifecycle costs by reducing trackside hardware. This implementation places Alstom at the forefront of a growing Indian railway signaling market, which is seeing major investment from competitors like ABB and a joint venture between Kernex Microsystems and Bharat Heavy Engineering.

The use of a mainline-derived ETCS signaling system for a metro line is a strategic move to foster network-wide interoperability, a long-term goal for India’s national rail plan. This approach blurs the traditional technical divide between urban and regional rail, potentially creating a more efficient, unified transport ecosystem. By proving the technology’s viability, Alstom gains a critical first-mover advantage in a market rapidly modernizing its signaling infrastructure, directly challenging competitors who are also expanding their Indian manufacturing and R&D capabilities.

FAQ

Q: What makes the Meerut Metro the first of its kind?

A: Meerut Metro is the world’s first metro system to enter commercial service using ETCS Hybrid Level 3 signaling over an LTE 4G wireless network. This technology is typically associated with mainline railways, not high-frequency urban transit.

Q: How fast are the new Namo Bharat and Meerut Metro trains?

A: The trains have a design speed of 135 km/h and a maximum operating speed of 120 km/h. This makes the Meerut Metro trains the fastest of their kind currently operating in India.

Q: Is this project part of a larger network?

A: Yes, the Meerut Metro is directly integrated with the Namo Bharat Regional Rapid Transit System (RRTS). The entire project is managed by NCRTC and is designed to connect Delhi with surrounding satellite cities to ease road congestion.
