Metrolink Lines with Sheriff Reporting Districts

This dataset was developed by LA County Urban Research in support of a project to map the Metrolink Lines and their related Reporting Districts for the Sheriff in 2006.

This dataset is fairly complex, since it uses a linear referencing model to ensure transfer information about reporting districts from a table of cities based upon the distance down a line.  That is the reason you will find segment length information.

The Sheriff provides law enforcement support across the Metropolitan Transit Authority (MTA) Metrolink system.  There are 7 Metrolink lines:

  • Antelope Valley
  • 91 Freeway
  • Inland Empire – Orange County
  • Orange County
  • Riverside
  • San Bernardino
  • Ventura County

Where crimes are committed inside of the rail cars, specific codes are used to report these crimes.  Where vandalism, burglary, etc are committed on the property where the rails pass through, reporting districts are based upon the line and the specific city where the crime occurred.

For example, the Reporting District (RD) for the crimes onboard the Orange county Line are:

  • 6130 in Los Angeles county
  • 6314 in Orange County
  • 6341 in San Diego County

Reporting Districts for crimes outside the cars include:

  • 6101 for City of Los Angeles
  • 6133 for Vernon
  • 6131 for Commerce
  • 6134 for Montebello
  • etc.

You can view the Reporting District map for the 91 Line (Sep 29, 2006) for one of the maps.
