Xbox Series X Birmingham To Crewe Sleepers And Ballast

What is wrong with the Sleepers and Ballast on Birmingham to Crewe. It looks like devs have tried to cover some sleepers with ballast to give it a more authentic look but under some lighting conditions the rails and sleepers look like they are separate from the ballast and in no uncertain terms it looks really bad.
I’ve checked other routes like Euston to Milton Keynes, GWR Remaster, Riviera Line, Preston Blackpool and Preston Carlisle with no issue.
Overall the Birmingham to Crewe route is excellent but this issue lets the route down and spoils immersion.

Niko….
