name:zh of feature?

abandoned rail track probably should have railway=subway instead

Calibrate/beautify path shape.

Clearly, the existing shapes are wrong, but the complexity of this junction requires some updated satellite imagery just to know the intricate shapes.

railway=disused seems like railway=crossover that is never actually used in standard operation

railway=disused is probably service=crossover; rail in the main line but not used in daily operation cannot be disused

Confirm bridge status

Cleanup needed
