a few things I noticed:
Carz
Even if you turn on traffic, the roads used do not have cars here
there are many roads that can be seen from the track while driving
it would add to the route
a few edited roads and we have cars
Seasons
There is some seasonal grass used, but not the trees as far as I can see
(not asking for total seasonal with snow)
Camera's
A lovely scenic route like this, would benefit from a few well placed camera's
so you can drive the route in mode 3
Boat
there is an oil tanker used far north west, it is a drivable one
but on a really short track, so you cant drive it, but ends up in the driverlist
maybe better to replace it for a scenery one
Windmills
a few Benstuff windmills were used, these are made as Industry, so they end up in drivercommands
for my own route I changed them to scenery items (had 200 used, reached industry limit)
Tram
Just discovered there is an entire Tram route possible in Schwaninger, not checked all sessions yet
but could be fun, to bad many tram parts suffer the PBR bugs
Olaf's nice GTL8 tram driving in Nimmerfehl, ofc. we lack the tram catenary
success working on this route, its lovely
enjoyed beta testing it
