Place them in a "tt" directory in the game's installation directory. Replacement lasts until you return to the main menu. A few network names: Basic Road Highway Highway Bridge Medium Road Medium Road Bridge Train Track Train Track Elevated Train Track Bridge Quay Flood Wall Canal Canal2 Canal3 You can easily find the prefab textures by selecting the network in the menu. Then in the Mod Tools scene explorer (CTRL + E), find Tool Controller > NetTool on the left and expand m_prefab > m_segments > m_segment[0] > m_segmentTexture on the right. The network must be selected while you do that. Here are a few example textures: Quay_D.png Quay_XYS.png Basic Road_D.png Basic Road_APR.png
