Standard
TrainPal's Travel Expert Experience
"Southern services can become crowded during the 07:00 to 09:00 and 16:00 to 19:00 commuter peaks, so travelling outside these periods can make longer journeys more comfortable. For Gatwick Airport, consider the front or rear sections of Class 377 and 387 trains for easier access to luggage space."
"If you have a Standard ticket, check the platform and onboard displays for First Class declassification before boarding, as these areas may occasionally be opened to Standard passengers. On longer journeys towards Brighton, Portsmouth or Southampton, checking the train formation before boarding can also help you position yourself near the luggage space you need."
