This layout is similar to another depot I've made (for 1-4 trains). I had to design a new depot for my Warehouse, namely for 2-4-2 and 1-4-1 trains-- both directional. The 2-4-2 depots are on the ID#16 network due both my Mining Outposts and infeed of the Warehouse being on the same network.
To reduce any chance for congestion at the entrance / exit of this depot I've made a sliplane parallel to the four tracks.
You can find my other prints, like the Warehouse and the Mining Outposts, in my profile.
