Electrified Dual-Track Inter-Terminal Rail Corridor to Interconnect JCT, SAGT, and CWIT, Eliminating Drayage Bottlenecks and Accelerating Subcontinental Transshipment Feeder Turnarounds


COLOMBO — In a landmark infrastructure decision aimed at fortifying its position as South Asia’s premier transshipment hub, the Sri Lanka Ports Authority (SLPA) has formally ratified the capital engineering blueprint for a dedicated internal Inter-Terminal Rail Link (ITRL) traversing the Port of Colombo complex.

The multi-million-dollar intermodal infrastructure project establishes an electrified, dual-track heavy-axle container rail corridor designed to seamlessly link the state-run Jaya Container Terminal (JCT) with private deepwater facilities, including the South Asia Gateway Terminals (SAGT) and the recently expanded Colombo West International Terminal (CWIT).

By shifting thousands of daily container transfers off internal harbor access roads and onto an automated quayside rail shuttle system, the initiative directly tackles acute yard-side truck congestion, cuts inter-terminal transfer times by over 40%, and provides mainline liner alliances with predictable connection windows for cargo feeding into and out of the Indian Subcontinent.

Resolving the Inter-Terminal Drayage Squeeze

The Port of Colombo handles over 80% of its total container throughput as transshipment volume, with the vast majority linked to Indian import-export (EXIM) feeder flows. However, the physical separation between legacy inner harbor docks and outer deepwater terminals has created chronic operational friction:

  • Surface Highway Saturation: Moving transshipment boxes between mother-vessel discharge berths (such as CWIT) and regional feeder berths (at JCT and SAGT) has historically relied on hundreds of internal terminal tractor-trailers (ITVs) and conventional road trucks. Peak vessel bunching regularly overwhelmed port gate corridors and terminal perimeters.

  • Feeder Connection Rollovers: Traffic delays across the port’s internal roads frequently caused transshipment containers to miss tightly scheduled regional feeder departures, stranding South Asian cargo in Colombo yards for days and triggering container rollover surcharges.

  • Quayside Dwell Penalties: Slower transfer speeds forced terminals to maintain wider buffer margins in yard stack allocations, tying up valuable footprint needed to service Ultra-Large Container Vessels (ULCVs) exceeding 20,000 TEU capacity.

The newly sanctioned ITRL corridor provides an uninterrupted, grade-separated rail conduit that moves container blocks directly between quayside cranes without entering the internal urban traffic grid.

Enhancing Subcontinental Transshipment Competitiveness

The operational integration comes at a crucial strategic juncture as neighboring regional ports—including India's transshipment gateways at Vizhinjam and the planned deepwater port at Vadhvan—scale up direct mainline capabilities:

  • Compressing Feeder Dwell for Indian EXIM Trades: Connecting deep-draft mother-vessel berths at CWIT directly with coastal feeder berths serving Chennai, Tuticorin, Cochin, Visakhapatnam, and Chittagong ensures that subcontinental industrial cargo transfers seamlessly without quayside queueing delays.

  • Protection for Perishables and Rebalancing Empties: The rail link includes dedicated power skids to provide continuous monitoring for refrigerated containers and dedicated nighttime slots to shuttle empty boxes between carrier pools, eradicating equipment mismatches across terminal operators.

  • Decarbonization Dividend: Replacing diesel tractor shuttles with electrified rail eliminates an estimated 22,000 metric tonnes of localized carbon emissions annually, aiding Colombo’s compliance with international green maritime benchmarks.

Statements from Port and Maritime Leadership

Announcing the approval at the SLPA headquarters in Colombo, senior port officials and terminal stakeholder representatives stated:

"The Port of Colombo cannot rely solely on deepening berths and adding ship-to-shore cranes; our landside velocity must match the speed of our quayside operations. The Inter-Terminal Rail Link transforms Colombo from a collection of isolated docks into a single, synchronized transshipment engine. By eliminating truck congestion and guaranteeing clockwork container handovers between CWIT, SAGT, and JCT, we ensure that global shipping lines receive the fastest, most reliable transshipment turnarounds in the Indian Ocean basin."

Civil ground-breaking for track laying and terminal siding modifications is slated to commence by the end of next month, with the first operational phase connecting CWIT and JCT scheduled for commissioning in mid-2027.
