In the Netherlands, we have national police, local police, military police, railroad police, forest police, border police, and so on. They are all fairly independent of each other and have separate jurisdictions.
The Dutch railroad police (as well as the water, traffic, and aviation police) was sadly disbanded in 2013 [1]. In the same year, all 25 local police forces were disbanded and replaced by one national police force [2].
In Sweden, there was until just recently, 21 regional indendepent police, plus a national investigative unit. (And the secret police and the military police.)
Now the 21 regional police have been merged into one national police.
