Train Reversal at Polegate

Due to engineering works, late night trains from London and Brighton sometimes terminate at Polegate for and onward bus service, and the trains then return towards London/Brighton using the crossover just beyond the level crossing.
On the night of 27th March 2024 I arrived at Polegate on the 1F68 2246 London Victoria to Polegate service. Unit 377433 then returned using the crossover to the Up line with the 2G73 0023 Polegate to Brighton service.
