Railway enthusiasts from all over the UK crowded onto the Gatwick Express on Thursday to say goodbye to two engines being retired after more than 40 years.
Rail fans flocked to photograph and film the train's final journey
The electro-diesel engines have been in use in the South East since 1962.
But they have been phased out as the fleet of 14 Gatwick Express trains have been replaced by newer rolling stock.
Trainspotters filmed the final journey and asked for guards to sign their tickets, while holidaymakers heading to Gatwick Airport looked on bemused.
The Gatwick Express runs between the West Sussex airport's railway station and London Victoria and the company's two longest-serving drivers were given the honour of driving the engines for their final journeys - one going in each direction.
Michael Seabrook said: "I've been driving them as a driver on the Gatwick Express since day one, which is just over 20 years.

"I feel really sad, it's like a big area of my life gone."
The managing director of Gatwick Express, David Stretch, travelled on one train, making an announcement to passengers thanking them for their appreciation of the historic relevance of the day.
He said: "It's a very proud yet sad moment. These locos have been in service with the Gatwick Express and the railway industry for many many years.
"Today is the final day and I'm really proud and happy to see so many of the travelling public, guests and friends of the Gatwick Express have come along to celebrate the last journey."
