Release notes: 

2.5

I had release a newer one of these on RWA a few months ago but didn't completely disable smoothing. Now it is. 
This is completely more effective than my original version I released over a year ago.

This essentially disables FXAA (less blur)

FXAA shader adjustments only.

Overview: 

This was designed for SSAA users only. You can try it if you want if you don't use SSAA but it may have more jaggies
This will nearly eliminate the blurry gameplay associated with TS-2013
This isn't a hack or exploit and anyone at home could have done this provided they downloaded the DirectX SDK

Installation:

Unzip the 1 file and copy it into \Railworks\Dev\Shaders\ 

Overwrite file when prompted (back them up if you wish)

I am not responsible if this breaks your game. You apply this at your own risk..
