Yes, the inter-terminal shuttle service at London Gatwick (LGW) is a 24-hour, 365-day operation. This automated, "High-Fidelity" monorail-style transit system connects the North and South terminals with a journey time of only two minutes. During the day, the shuttle runs every few minutes; in the late-night hours (typically between 23:00 and 06:00), the frequency may decrease to every 10 minutes as the system often switches to a single-track operation for maintenance. The service is entirely free of charge and is located before security, allowing passengers and visitors to move between the rail station (in the South Terminal) and the North Terminal at any time. This "High-Fidelity" reliability ensures that travelers with early morning 2026 departures can access their gates without the stress of missing a connection due to terminal distance.
