徐紀(jì)康 提供素材

阿爾斯通在印度密魯特地鐵啟用了全球首個(gè)基于LTE 4G網(wǎng)的ETCS-3級(jí)信號(hào)系統(tǒng)的地鐵線路。該線路是德里—密魯特區(qū)域快速走廊的一部分，該線路覆蓋新建21公里地鐵線路及26.5公里區(qū)域快速線路。

技術(shù)參數(shù)

核心創(chuàng)新在于：在4G無線網(wǎng)絡(luò)上部署ETCS-3級(jí)信號(hào)系統(tǒng)。該系統(tǒng)架構(gòu)通過列車自主上報(bào)定位信息與基于無線通信的行車管理，降低了對(duì)軌道電路等傳統(tǒng)軌旁列車檢測(cè)設(shè)備的依賴。區(qū)域快線與地鐵列車均采用阿爾斯通的Adessia平臺(tái)列車，列車設(shè)計(jì)時(shí)速135公里，最高運(yùn)營(yíng)時(shí)速120公里，為印度速度最快的城市地鐵列車。

該技術(shù)在市場(chǎng)中的定位

在大運(yùn)量城市軌道交通領(lǐng)域，全球主流標(biāo)準(zhǔn)是基于通信的列車控制系統(tǒng)（CBTC），而將ETCS-3系統(tǒng)應(yīng)用于地鐵，是一次重大突破。

阿爾斯通該系統(tǒng)直接對(duì)標(biāo)西門子Trainguard MT、泰雷茲SelTrac等成熟CBTC產(chǎn)品。CBTC是地鐵專用解決方案，而ETCS則是鐵路互聯(lián)互通標(biāo)準(zhǔn)；將其應(yīng)用于地鐵運(yùn)營(yíng)，體現(xiàn)了區(qū)域鐵路與城市軌道網(wǎng)絡(luò)融合的戰(zhàn)略方向。

相較于依賴地面歐洲應(yīng)答器進(jìn)行位置更新的傳統(tǒng)ETCS-2系統(tǒng)，ETCS-3大幅減少軌旁硬件，靈活性更高，全生命周期成本也可能更低。此次落地使阿爾斯通處在印度鐵路信號(hào)市場(chǎng)升級(jí)的前沿，該市場(chǎng)正吸引ABB、Kernex與巴拉特重型電氣合資公司等競(jìng)爭(zhēng)對(duì)手大舉投入。

將源自鐵路的ETCS信號(hào)系統(tǒng)用于地鐵線路，是推動(dòng)全網(wǎng)互聯(lián)互通的戰(zhàn)略舉措，也是印度國(guó)家鐵路規(guī)劃的長(zhǎng)期目標(biāo)。這一模式打破了城市軌道與區(qū)域鐵路之間傳統(tǒng)的技術(shù)壁壘，有望構(gòu)建更高效、一體化的交通生態(tài)。

常見問題

問：密魯特地鐵為何堪稱全球首創(chuàng)？

答：密魯特地鐵是全球首條正式投入商業(yè)運(yùn)營(yíng)、采用ETCS-3信號(hào)系統(tǒng)+LTE 4G的地鐵系統(tǒng)。這類技術(shù)以往多用于鐵路，而非高密度的城市軌道交通。

問：該項(xiàng)目是否屬于更大交通網(wǎng)絡(luò)的一部分？

答：是的。密魯特地鐵與那摩·巴拉特區(qū)域快速運(yùn)輸系統(tǒng)（RRTS）直接一體化銜接。整個(gè)項(xiàng)目由國(guó)家首都地區(qū)運(yùn)輸公司（NCRTC）管理，旨在連通德里及周邊衛(wèi)星城，緩解地面交通擁堵。

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.
