CAG Calls for Stricter Railway Maintenance Amid 3,000 Annual Signalling Failures
CAG highlights 3,000 annual signalling failures in South Western Railway, urges stricter maintenance.

The Comptroller and Auditor General (CAG) of India has urged the South Western Railway (SWR) zone to implement a stricter maintenance mechanism for its signalling systems. This recommendation comes in the wake of a concerning statistic: SWR reported approximately 3,000 signalling failures annually between 2018-19 and 2020-21.
The CAG's audit revealed that these failures were primarily due to issues like cable damage, track circuit failures, and point machine malfunctions. This report underscores the critical need for robust maintenance to ensure railway safety and operational efficiency, a key aspect of India's infrastructure development.

SWR Signalling Failures & Causes (2018-2021)
Key statistics from the CAG report highlighting the scale and primary reasons for signalling failures in the South Western Railway zone, underscoring the urgency for improved maintenance.
- Annual Signalling Failures (SWR)
- ~3,000
- Primary Causes of Failures
- Cable Damage, Track Circuit Failures, Point Machine Malfunctions
- CAG's Recommendation
- Stricter Maintenance Mechanism
This high number indicates a significant safety and operational risk, impacting punctuality and potentially leading to accidents. It highlights a systemic issue in maintenance.
These technical issues point to inadequate preventive maintenance, aging infrastructure, or lack of timely repairs. Addressing these specific causes is vital for improving safety.
The CAG's call emphasizes the need for a proactive and systematic approach to maintenance, moving beyond reactive repairs to prevent failures.

Background
The Comptroller and Auditor General (CAG) is a constitutional body established under Article 148 of the Indian Constitution. It is the supreme audit institution of India, responsible for auditing all receipts and expenditures of the Union and State governments, including those of bodies and authorities substantially financed by the government. Its reports are crucial for parliamentary oversight and public accountability.
Indian Railways, a vital part of India's infrastructure, operates one of the largest railway networks in the world, playing a crucial role in economic development and public transport. Ensuring its safety and operational efficiency, particularly through robust maintenance of critical systems like signalling, is paramount.

Practice Questions (MCQs)
1. Consider the following statements regarding the Comptroller and Auditor General (CAG) of India: 1. The CAG audits the accounts of the Union and State governments, including the expenditure of public sector undertakings like Indian Railways. 2. The CAG is appointed by the President and can be removed from office only through a process similar to that of a Supreme Court Judge. 3. The CAG's audit reports are directly submitted to the Parliament for discussion and approval by the Public Accounts Committee. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 2 only
- C.2 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is correct. The CAG audits all receipts and expenditures of the Union and State governments, including government companies and corporations where the audit is entrusted to it. Indian Railways is a major government undertaking. Statement 2 is correct. Article 148 of the Constitution provides for the appointment of the CAG by the President and removal in the same manner as a judge of the Supreme Court. Statement 3 is incorrect. The CAG submits its audit reports relating to the Union to the President, who shall cause them to be laid before each House of Parliament (Article 151). While the Public Accounts Committee (PAC) examines these reports, it does not 'approve' them; rather, it scrutinizes them and presents its findings to Parliament. The reports are for discussion and parliamentary oversight, not direct approval by PAC.
2. In the context of railway safety and regulation in India, consider the following statements: 1. The Commissioner of Railway Safety (CRS) functions under the Ministry of Railways and is responsible for statutory investigations into serious railway accidents. 2. 'Kavach' is an indigenously developed Automatic Train Protection (ATP) system aimed at enhancing railway safety by preventing collisions. 3. The Railway Board is the apex body for railway administration, policy formulation, and overall management of Indian Railways. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is incorrect. The Commissioner of Railway Safety (CRS) functions under the administrative control of the Ministry of Civil Aviation, not the Ministry of Railways. This institutional separation ensures the independence of railway safety inspections and accident investigations. Statement 2 is correct. Kavach is India's own Automatic Train Protection (ATP) system, designed to prevent collisions by automatically applying brakes if the loco pilot fails to control the train. Statement 3 is correct. The Railway Board is indeed the highest decision-making body for Indian Railways, responsible for its overall administration, policy, and management.
3. Which of the following statements is/are correct regarding railway signalling systems and their maintenance challenges in India? 1. Track circuits are essential for detecting the presence of a train on a section of track and are critical for interlocking systems. 2. Point machines are electromechanical devices used to operate railway points (switches) to guide trains from one track to another. 3. The primary challenge in maintaining railway signalling systems in India is solely the high initial cost of modern electronic interlocking systems, rather than environmental factors or human error. Select the correct answer using the code given below:
- A.1 only
- B.2 only
- C.1 and 2 only
- D.1, 2 and 3
Show Answer
Answer: C
Statement 1 is correct. Track circuits are fundamental components of railway signalling, used to detect trains and provide vital inputs to interlocking systems, ensuring that conflicting movements are prevented. Statement 2 is correct. Point machines are crucial for changing the direction of trains by moving the railway points (switches) at junctions and sidings. Statement 3 is incorrect. While the high initial cost of modern systems is a challenge, it is not the 'sole' or 'primary' challenge. As highlighted in the news (cable damage, track circuit failures, point machine malfunctions), environmental factors (weather, vandalism), aging infrastructure, human error, and inadequate maintenance practices are also significant challenges in maintaining railway signalling systems in India.
