Logistics bottlenecks for over-dimensional cargo have historically delayed India's energy projects. Examine the current regulatory framework and suggest reforms.

In 1976, BHEL Tiruchi built a steam generator weighing over 60 tonnes for the Kalpakkam atomic power project. It was too wide for rail. It then waited 13 days at the factory gate for highway clearance before taking a detour via Perambalur [1]. Rules for such over-dimensional cargo (ODC) have improved since, but they are still split across agencies.

Current regulatory framework

• Roads: MoRTH regulates over-weight and over-dimensional loads on National Highways. Its 2014 circular tied their movement to a condition survey of bridges [2]. Its 2020 circular brought in online permits for single-unit loads on Modular Hydraulic Trailers [3].
• Rail: A load counts as ODC if it exceeds the Standard Moving Dimensions at any point on the route. On electrified sections, the Section Controller and Traction Power Controller must coordinate, power may be cut and speed is capped [4].
• Waterways: IWAI calls NW-1 safe for ODC. Steam-turbine and generator parts moved on it in 2017-18 [5].
• Planning: The PM GatiShakti National Master Plan maps all transport modes on one platform [7]. India's first official estimate puts logistics cost at 7.97% of GDP (2023-24) [6].

Gaps

• NH-only coverage: The circulars apply only to National Highways. State highways and district roads, like the Perambalur detour, have no advance bridge-load data [1][2].
• Rail's tightest point: A single narrow bridge or platform blocks the whole route, and electrification adds more checks [4].
• Ports: Safety rules allow ODC handling only in daylight [5].
• Late route planning: Routes are checked only after the equipment is built. A national cost average also hides the high cost of one-off heavy loads [1][6].

Reforms

• Route checks at the DPR stage: NPCIL, BHEL and other developers should check heavy-cargo routes on the GatiShakti portal before ordering equipment [7].
• One national ODC window: States should survey bridges on the roads leading to plants and link their permits to MoRTH's online system [3].
• A digital bridge-capacity registry across NH, state and rail assets, built on the 2014 survey approach [2].
• Ports and rivers: Allow ODC handling at night under safety SOPs [5]. Use IWAI river-and-sea routes for coastal and river-side energy sites [5].

The rules have moved from in-person sign-offs to digital permits, but they still stop at the NH boundary. Combining state road data, multimodal routing and planning at the design stage would cut avoidable delays. That supports GatiShakti's goal of lower logistics costs and SDG-9 (resilient infrastructure).
