Departing from and arriving at Cosham
Before departing from Cosham
Use Cosham (CSA) in the departure field and check the platform for your booked direction. Keep all tickets available for inspection, including every part of a split-ticket journey.
If your booking offers ticket collection at Cosham, the recorded machine location is northeast entrance. Check the collection instructions and allow time before your train; a listed machine is not confirmation that every ticket can be collected there.
When arriving at Cosham
Select Cosham (CSA) as the arrival station and plan the onward journey from that station, rather than from the centre of the wider area. Check your return departure separately, particularly when the return train uses a different platform.
Cosham has recorded Category B1 access. Check the platform access notes for both your outward arrival and return departure before choosing your trains; a step-free route in one direction does not establish access in the other.
