If you want my suggestion, I would say area beautification, design and place lighting and other props that may be found along the side of the track.
Ideally, we would try to keep mobs from spawning near the tracks, mobs spawn in lighting 7 or lower.
The train-stop at the mesa is yet to be built.
I haven’t started the railway to purr’s that is next on the main railway list.
we have plenty of iron and wood, we have a decent amount of gravel. stone we are a little low on but that’s ok it’s the most common resource in the game. Don’t need to focus too much on gathering.
