Does the Colton & Northern Addon for RailWorks on Steam come with the HiRes Roads and Folage from 3DTrains or will I need to buy them from 3DTrains?
According to their website; yes.

Important before purchasing! The Colton & Northern requires add-ons for you to get the full effect of the beautiful scenery of the route. Please note that the extra add-ons are available from their respective sites. Please also note that some of these add-ons have free counterparts where you can upgrade to their pay (hi-res) versions at your convienence.

From 3dTrains, you will need:
1) Rural Landscapes (lo-res is free, hi-res available for purchase.)
2) Scale Roads (lo-res is free, hi-res available for purchase.)
...
Important! If you already have these add-ons, you don't need to purchase them again.
