I often take trains that go through either Gatwick or Southampton Airport Parkway. At both these stations a whole bunch of people with suitcases get on and are then a bit flummoxed because there isn’t anywhere for the suitcases to go.
There’s a rack above the seats but it won’t take much more than a soft bag and coat. The Gatwick train does have a couple of luggage racks but nowhere near enough for all the luggage. AIBU to think this is actually quite weird?
