Although much of the Bellisseria continent has railway tracks connecting the various themes together, a lot of it is still unusable.

This is because railway track switches/points - which are a neccesary to move trains from one track to another track - are completely absent, or have been completely forgotton about.

The Log Homes theme continent has an extensive network of railway tracks winding through most of it. But much of the theme's tracks don't have switches/points at the track intersections, meaning trains are unable to change tracks.

It's impossible to drive a train from the Log theme northwards into the Welcome Hub regions, even though there's a railway station there! There's no switches to allow it!

Ranch Theme has a coastal railway which was hoped to be a complete circle around the theme's perimeter, but Ranch Theme building has come to a sudden halt and the theme's southern edge remains missing, unbuilt and has no tracks to complete the circle.

Mediterranean Theme has a railway track running through it, but once again, it has no switches and is isolated from the rest of the SLRR.

Sakura Theme has a single railway station in it. However it isn't connected by railway track to any other Linden Homes theme and remains isolated and underused.

Please complete the Bellisseria SLRR network, placing switches/points at all railway track intersections. And also place track extensions linking all the Linden Homes themes together in an effort to make the existing SLRR worthwhile, as large sections of it are inaccessible and are seemingly "pointless".... (!)

ADDITIONAL INFO (Update)

I did a survey of the Log Theme's railway. It can be fixed/corrected by adding three switches/points to existing tracks/junctions located in two Log sims named "Three Sheets" (needs 2 switches/points) and "Gully Wash" (needs 1 switch/point).
