CAG audits often reveal a gap between policy intent and implementation on the ground. Discuss with reference to recent findings on Indian Railways' bio-toilet infrastructure.

The CAG, deriving its mandate from Articles 148–151, uses performance audits to test not whether money was spent but whether the intended outcome was achieved. Its Report No. 31 of 2026 on passenger amenities and sanitation at non-suburban stations, examined by the Public Accounts Committee (PAC), shows how a flagship sanitation initiative survived on paper while failing on the platform [1].

The intent versus the audited outcome

• Bio-toilets were promoted as a sanitation "game changer", first audited in CAG Report No. 36 of 2017 on coaches [1].
• The 2026 audit found bio-toilets deficient or non-functional at 491 of 512 stations inspected (~96%) — the failure is of upkeep, not installation [1].
• Allied basics also lapsed: 188 stations lacked adequate drinking water and 97 lacked high-level platforms [1].

Accessibility: a statutory duty, not a courtesy

• 74% of stations were non-compliant on Divyang-friendly toilets; tactile guiding blocks were missing at 65% and priority seating at 96% [1].
• These are entitlements under the Rights of Persons with Disabilities Act, 2016, and are expressly mandated by Amrit Bharat Station Scheme guidelines — proving the standard existed and was simply unenforced [4].

Why the gap persists

• Fiscal: operating ratio budgeted at 98.4% for 2026-27, with 90% of revenue expenditure locked in salary, pension and lease; the Depreciation Reserve Fund is only ₹1,500 crore against ₹2.93 lakh crore capex — creation is funded, maintenance is not [3].
• Incentive: 103 stations were redeveloped at over ₹1,100 crore with lifts and accessible toilets [2], while ordinary stations failed basics — visible projects outrank invisible maintenance.
• Accountability: PAC has flagged these gaps in four reports since 2007, each closed by an action-taken report without field verification [5].

Thus scarcity explains the pace of failure, but weak follow-up explains its scale. Ring-fenced maintenance funding, outcome-linked zonal accountability, and PAC's own instrument here — a one-month deadline plus a public follow-up hearing [5] — can convert audit findings into genuine service delivery, aligning Railways with SDG-6 and constitutional equality of access.
