There's two possible POI's that I think should be added; "Rail Bridge" and "Bridge Over Railway". Both of these are in Nearly every village, town and city in the country.
Calls for Rail Bridge could include "Vehicle struck rail bridge", "Rail bridge collapse", as well as the existing train derailment and embankment fire calls.
Calls for Bridge Over Railway could include "Vehicle crashed onto railway", "objects thrown onto rail line", "fallen tree blocking line", as we as the existing derailment, embankment fire, welfare check and person under train calls.
