All that track connected to the depot you are talking about is high speed passenger infrastructure. Just touching the south side of the factory is what looks like an old single track line if you follow it to the west there's a passing loop just the other side of the nearest village. If you switch to back and forth between map view and satellite view this eventually leads to a spur shown in map view that stops at a road. Not sure if the line is under construction or decommissioned or what.
