One scenario for the South London to Brighton Workshop route by Danny Leach.
1U43 09:20 Gatwick Airport-London Victoria (45 mins, medium)
Take this Class 460 from Gatwick Airport to London Victoria during the tail end of Rush Hour, you were supposed to have a Class 442 for this service but due a fault on a previous service, it limped into the sidings at Gatwick Airport and was rescued by another Class 442. You have been given one of the Class 460s from Stewarts Lane instead. There are a few delays this morning to a track circuit failure at London Victoria whilst you had your break after working 1D30.
