Bug With Brightness In Tunnels In Csx Heavy Haul

I can tell what this a bug but it's really a bit uncomfortable:

The brightness in tunnels isn't detailed cause when you enter tunnel the train is still bright of weather and in the cabin too:

you can see this brightness because of sun shining through the tunnel. Can you fix this or it's a problem because of video card Nvidia GeForce 960 2gb VRAM?

 

Known issue since the TSW beta. DTG don't care to fix this and other issues on the sand patch route.

 

The sand patch won't be fixed?

 

I doubt it, there where no fixes in the last patches for the sand patch route and i guess there wont be one in the future.

 

I think they fixed that. It came with NEC route. Tunnel darkness.

 

Anthony Pecoraro: Tunnel darkness was introduced with rapid transit, but never was fixed in the sand patch route. Still bright trains in the dark tunnel.
