Here's a visual.
From the front of the mill (left to right):
- Pouring track
- Charging box track (at rear of mill)
- Charging machine (wide) track (also at rear of mill)
- Run-around track (front at ground level)
- Hot metal transfer track (directly above it and charging floor). This is not visible or labeled per se. I don't have enough real estate to take this track up to this level and keep the run-around track below it.
The three spurs to the right are for the blast furnace.
