I thought I would throw out a new thread for unique operations which like me you would never know actually existed today. A while back I came across a modern isolated freight railroad in rural eastern Canada with a 7 mile mainline which requires interchange with CN by car ferry. The railroad itself put out a very interesting promo video and is worth a watch as it has some great scenes of a CN rail ferry being switched. This is also a relatively new railroad built in 1976, when similar lines were being torn up. This also could be a route that would be very simple to build and fun to operate in our sim and is very unlike any other rail operation on the east coast of North America, operations like this simply do not exist anymore with the exception of a very small list. This one is a modern contradiction. Links are below for the promo video and company website.
