Hi! I think this addition would be of better immersion because there are coastal cities in Europe that really experienced heavy bombing and any move to that direction adds realism.
Still not a critical for a subsim, but anyway any visible change in the condition of cities especially in 1944-1945 would be nice. That would of course require different house structures. This was also slightly offtopic so I will bring this up in another thread.
Anyway, I think railroad coastal artillery is a good idea.
