Southport Lakeside Miniature Railway

Something different and short , only 750 yards in length but could be a fun and niche train to drive on, hard to imagine what kind of scenarios you could have but why not have a railway like this

 

Maybe a fun DLC for a few euros on April 1st, but otherwise, I don't see a lot of market for it

 

I think the route would have to be longer, more like the Romney, Hythe & Dymchurch Railway, but it's a really good concept.
