There two primary ways to build stations with our rail mods, the termination station style and the pass-through style.
This type of station is well suited for terminating a rail line.
If you need to make an in-line station where riders can enter from one end and leave another, you need to use a pass-through station.
This station works pretty the same as the termination station, except that the dispenser is underneath the track.
You can then use two of these for one stations, as illustrated below.
If there are several incoming tracks (for example, a central hub), you can use several of these passthrough rail setups adjacent to each other.
