I have mods but no custom wagons or stations were used here.
Station is placed on the fifth straight rail after the curved rail, used a 2-3-0 and let the train pull up to the station.

Here's a picture of a 2-12-2 with two inserters on the edge of each cargowagon, The chests represent what Item was pulled OUT of the cargo wagon by an inserter and the cargowagon is where the items ended up when INserting.
