I have pretty much completed my track laying - just putting in some final spurs and service lines. Moving more to scenery now. While planning my layout, I never gave much thought about design consideration for two-way directional travel on the layout. For example, what service lines should be entered from the “front” and what ones are more appropriately be “backed” into. I have two yards and right now each yard sends trains onto the mainline in the opposite direction of the other yard.
While I don’t have any regrets, but any design thoughts on this issue?
Thanks!
