In 2026, trains from Gatwick Airport to London (Victoria, London Bridge, or St. Pancras) are unique because service never truly stops running entirely. While the high-frequency "Gatwick Express" and "Thameslink" services reduce their frequency in the early hours of the morning (typically between 1:00 AM and 5:00 AM), there are almost always hourly "Night Trains" or "Southern" services that operate throughout the night. For a standard 2026 schedule, the last "peak" frequency trains usually depart around 11:55 PM or midnight, after which the "Night Service" takes over with one or two departures per hour. This makes Gatwick one of the most accessible London airports for late-night arrivals. However, travelers should always check for "Engineering Works," which frequently happen on weekend nights (Saturday night/Sunday morning), during which time the trains may be replaced by "Rail Replacement Buses" that take significantly longer to reach central London.
