Can you reach any castle within 40 miles of Southend-on-Sea by train?

Those are straight-line distances from the station to the castle, so the walk on the ground is longer than the figure.
Can you go inside every castle within 40 miles of Southend-on-Sea?
Not all of them on the same terms. 2 of the 25 restrict what a visitor can see. Lympne Castle is a hotel, so there is no way in without booking a room or a table. At St Leonard's Tower the building itself isn't open to visitors, so you see it from the grounds or from outside.
