Bit of an odd question I know, but does anyone know of any routes beyond the three that have the Dawlish Seawall that feature seawalls?
That depends what you mean by a sea wall. A sea wall next to a track? A sea wall made from masonary? Or something else? Cornish Main Line has artificial boulder and dune sea walls at Penzance. The Kyle Line has extensive but intermittent sea edge running, but that's natural or blasted rock face.
North Wales Coastal has a variety of sea walls, none are as long as the Riviera, but has more variety of construction and setting.
The japanese Hidaka Main Line also goes by the sea. Not really a proper seawall, but going pretty close alongside the sea.
Do you like breached seawalls? If so you’ll love this… https://alanthomsonsim.com/downloads/g-g-s-1c75-0937-london-paddington-to-paignton/
Looks good! Looking at the requirements, how does this integrate with the AP EPs? Presumably no conflict? Class 43 Revamp Pack – (Major Wales Design)
[Removed - Alex - Aggrevating other users] Yes it works fine with the AP enhancement, but then it would seeing as the AP packs are requirements for the Class 43 Revamp Pack to work!
