RailtoRail

Railtorail is a proposed interoperable rail concept intended to enable seamless movement of passengers and freight across multiple railway networks with differing gauges, electrification, and signaling standards. The term is used in transportation planning discussions and does not refer to a single operational system.

Its core idea is to employ modular rolling stock and adaptive track interfaces that can operate on systems with variable gauges, while aligning with common safety and control standards. Key technologies associated with Railtorail include variable gauge axles or automatic gauge-changing systems, modular dual-mode power supplies, standardized train control interfaces, and rapid transshipment facilities at interchanges. The concept also anticipates centralized traffic management to coordinate cross-network movements.

Railtorail emerged in academic and industry discussions as a response to borderless freight corridors and congested cross-border routes. Proposals emphasize pilot projects integrating existing gauge networks through temporary or semi-permanent infrastructure upgrades, and collaboration among national rail operators, regulators, and manufacturers to test integration approaches and governance models.

Advocates argue that Railtorail could reduce transfer times, improve freight reliability, and expand passenger routes in regions with fragmented rail systems. Challenges include high capital costs, the need for standardization of vehicle design and signaling, safety certification, and governance for cross-border operations. Several pilots have been proposed to test component technologies, interoperability agreements, and business models.
