METRA/SUBURBAN MASS TRANSIT DISTRICTS

Prior to the RTA's creation in 1974, communities along 4 Chicago area commuter lines formed "Suburban Mass Transit Districts" as a means of obtaining federal and state funding for new equipment and other improvements. The transit districts would become owners of the equipment.

Chicago South Suburban Mass Transit District (CSSMTD)
Formed along Illinois Central (now Metra Electric).
During 1970's acquired electric MU cars used on that line, since retired.

West Suburban Mass Transit District (WSMTD)
Formed along Burlington Northern line.
Now owns all cars used on that line, except for the new Amerail accessible cars.
Formerly owned 25 ex-BN E9 locomotives, since retired.

Northwest Suburban Mass Transit District (NWSMTD)
Formed along Milwaukee Road West Line.
In 1974 acquired 13 new F40C locomotives and 36 new cars.
Also assumed ownership of 62 ex-Milwaukee Road cars.

North Suburban Mass Transit District (Nortran)
Formed along Milwaukee Road North Line.
In 1974 acquired 2 new F40C locomotives and 5 new cars.
Formerly owned 7 ex-Milwaukee Road E9 locomotives, since retired.

All of these transit districts continue to exist and still own the equipment, except for NWSMTD and Nortran, which have since dissolved.
