After downloading the google drive, simply find the folder called "Assets".

Now in a new folder window open the "Railworks" folder. 

To install simply drag the "assets" folder from the google drive on top of the Railworks folder. 

To check it has worked go into the "Railworks" folder and you should find the subfolders: "Railworks > Assets > RS > Addons > *Pack*"
