The Hayling Seaside Railway is at the southern end of Hayling Island (near Portsmouth) and adjoins the sea front and visitor amusements. The shop and workshops are currently ( autumn 2015) being relocated from the western to eastern end of the line. The line does sell postcards featuring its own operations. The service is volunteer operated. Whilst not as old as many seaside narrow guage lines there are historical elements to find such as sections of track recovered from the old Alton Towers
The cards available in September 2015 are detailed here ( click on link below to view postcards)
