Many years ago, as a site geologist, we were drilling boreholes in the sea bed just to the east of the pier in planning for a marina - never built. Such investigation works are carried out 24/7 and I vividly recall having to walk the length of the pier on occasion, at night, carrying equipment, or going out to the end to position the drilling craft for its next borehole. That was a long walk at night. There was a tourist train, but not for me.
