Former Dispatching Operations

Ann Arbor Railroad

Early on until 1981 - Dispatcher in Owosso.  In 1981, control of the track from Osmer (north of Ann Arbor) south moved to Michigan Interstate (later the reconstituted Ann Arbor Railroad) operator at Hallet.

Boyne City, Gaylord & Alpena

Dispatcher in Boyne City, main line east to Alpena.

Canadian National

See Grand Trunk Western for the lower peninsula.  The upper peninsula was controlled by Stevens Point, WI north dispatcher including the Manistique, Newberry, Lanse, Ore, Marinette, Iron Mountain and embine Subdivisions (former Wisconsin Central routes).  The CN central dispatcher, also at Stevens Point, controlled the White Pine subdivision from 0700 to 1500 Monday through Friday.

Conrail (Consolidated Rail Corporation)

This operation took over dispatching operations from Penn Central, and little was changed from the NYC, PRR and Penn Central operations. See those categories below. For current Conrail Shared Assets lines today, see Existing Dispatch Centers.

Chesapeake & Ohio

See Pere Marquette.


CSX moved all dispatching to a central facility in Jacksonville, FL. The AW desk controlled lines west of Trowbridge to Porter, IN and branches to Fremont, Ludington and Manistee. The AX desk controlled lines from Toledo north to Midland, and the Detroit to Trowbridge line via Plymouth. The BX desk controlled the Toledo Terminal and the Lincoln Secondary from Carleton to NS Bridge in Melvindale.

Detroit & Mackinac Railway

The original D&M was dispatched from two locations. One in East Tawas controlled the south division between North Bay City and Alpena, as well as branches. The second dispatcher was located at Alpena Junction, at the rear of the roundhouse. This included their main line and the Valentine Lake Branch (old Alpena & Northern). Both of these operations were confirmed by a 1902 D&M timetable. A 1911 timetable indicated that these were dispatched "by telegraph" except that the Rose City branch was dispatched "by telephone". The D&M purchased the AuSable & Northwestern which according to timetables was controlled elsewhere, possibly by the AuSable operator. All dispatching operations were consolidated to Alpena at some point. They were moved to Tawas in the 1990's after sale to Lake States Railway, and then to Saginaw.

Detroit & Toledo Shore Line

Dispatcher was located at Lang Yard offices near Toledo.

Detroit, Toledo & Ironton Railroad

Prior to Ford ownership, it appears that DT&I (and predessor) lines in Michigan were dispatched from facilities in Tecumseh. During some of this period, the DT&I dispatcher controlled the LS&MS line from Tecumseh to Dundee on which the DT&I had trackage rights. After Ford ownership in the 1920's, dispatchers were located at DT&I's office building in Dearborn.

Duluth, South Shore and Atlantic

Most Michigan lines were controlled by dispatchers in Marquette.

Escanaba & Lake Superior

Originally dispatched from offices in Wells. Later moved to Channing after takeover of MILW lines north of Green Bay.

Grand Trunk Western

Originally GTW was dispatched by local dispatchers. A Battle Creek West Dispatcher (located in the depot) handled the South Bend Subdivision main line and the Kalamazoo Subdivision from Pavillion to the north side of Kalamazoo. The Battle Creek East dispatcher handled the Flint subdivision from Battle Creek to Port Huron. The Detroit Dispatcher handled the Grand Rapids, Saginaw, Holly (Detroit to Durand), Mount Clemens (Detroit to Port Huron), the Cass City, Romeo, Greenville, Jackson and Muskegoin subdivisions.

From at least 1935 to at least 1974, the GTW had a dispatcher at Pontiac Yard, who dispatched the Holly subdivision, and probably other lines which radiated from Pontiac such as the Air Line to Jackson. In 1974, the CTC which covered the Holly Sub from M.A.L. Junction (in Pontiac) north to Durand was controlled by the GTW Pontiac dispatcher.

These dispatchers were consolidated and moved at some point to the 2nd floor of Durand Union Station and then in 1971 to Pontiac Yard.

At some point, they were again moved to corporate offices in Troy. In Troy, TD-2 controlled the Mt. Clemens, Holly and Shoreline subdivisions. TD-3 controlled the Flint subdivision from Battle Creek to Port Huron (and the entire Bessemer & Lake Erie). TD-4 controlled the South Bend and Elsdon subdivisions from Battle Creek to the Chicago area.

This area needs additional research.

Indiana & Ohio

Dispatching was moved from GTW to Cincinatti, OH when the I&O was formed. Unknown status.

Lake Shore & Michigan Southern

See the New York Central.  At various times, the Lake Shore had dispatchers located in Elkhart (controlling the line from White Pigeon to Grand Rapids), White Pigeon (controlling the same branch to Grand Rapids) and Hillsdale (controlling many LSMS branches in Michigan). During much of the NYC era, Michigan lines were controlled from Toledo (Old Road) or Hillsdale (other Michigan branch lines). The dispatchers in Hillsdale were located in an office building east of the Hillsdale depot. The building still exists and is used by the Indiana & Northeastern.

Lake Superior & Ishpeming

LS&I dispatchers were in Marquette. During the 1960's, lines of the LS&I, DSS&A and Chicago & Northwestern were consolidated and dispatched by the DSS&A in Marquette, much of it using CTC. The CTC machine was later transferred to the LS&I control operator at Eagle Mills.

Milwaukee Road

Most Michigan lines in the Upper Peninsula were dispatched from Channing.

New York Central

6 main dispatching centers covering Michigan and nearby areas.

Bay City. Covered Saginaw to Mackinaw City, branch lines. Lines in Saginaw were automatic block system in later years. Others were dark territory. Dispatcher was located at the Bay City East Side station.

Chicago East. Covered Chicago east to Porter and Elkhart

Detroit. Covered Alexis (Toledo) north to Detroit and Saginaw. Also a Detroit Terminal (Yard) dispatcher who covered Windsor to Town Line (Dearborn) and YD (River Rouge) to North Yard (north Detroit). Dispatchers located at Michigan Central station.

Hillsdale. Dispatched most old LS&MS lines in the first (south) tier of counties, including the Monroe Branch, Fayette Branch, Jackson Branch, Lansing Branch, Fort Wayne Branch, and White Pigeon to Grand Rapids Branch. Did not dispatch the Old Road (dispatched by Toledo). Dispatcher located at the Division office building, east of the NYC depot at Hillsdale.

Jackson East and West. Jackson east dispatcher covered from Town Line (Dearborn) to Jackson, and the branch from Jackson north to Saginaw. Jackson west dispatcher covered main line from Jackson to Niles and branches including the Air Line and Grand Rapids branches. Originally located in an office building at Jackson Jct. (yard area) they were moved to Jackson's depot in the 1960's. The Air Line was converted to CTC in the 1950's to handle increased high speed freight traffic from Jackson to Elkhart Terminal.

Toledo East, Toledo West and Toledo Yard dispatchers. Toledo East main line handled Vickers east to Berea and other branch lines. Toledo West handled the main line Nasby west to Elkhart and the Old Road from vulcan (Toledo Terminal) to White Pigeon. Both main line segments changed from 3-4 track automatic block signals to mostly 2-track bi-directional CTC in the 1950's.

Other lines needing research: Cincinnati Northern line from OH to Jackson, and the Benton Harbor Branch from IN to Benton Harbor.

Norfolk Southern

After NS purchased ownership of Conrail with CSX, they took over operation of the Conrail Dearborn dispatchers covering most Michigan lines. The old Wabash line continued to be dispatched from Fort Wayne until it was moved to NS Dearborn dispatchers in 2014.

Norfolk Western Railroad

See Wabash Railroad. Montpelier, OH.

Pennsylvania Railroad

Southeast Michigan dispatched from Toledo, including the line from Bucrus, OH to Galena (Toledo) and the Carleton to Lincoln Yard (Lincoln Park) branch. Their Fort Wayne, IN dispatcher controlled lines north from Indiana to Mackinaw City, and other branch lines in Michigan. This ended sometime after the Penn Central merger. Needs researching.

Pere Marquette (including Flint & Pere Marquette)

The Pere Marquette had dispatchers in Detroit, Grand Rapids and Saginaw. Needs additional research.

In 1898, the F&PM had dispatchers in Saginaw and Port Huron.

Soo Line

Dispatched from Gladstone, MI?

Tuscola & Saginaw Bay

T&SB took over state-owned rail lines in central michigan, including most of the Ann Arbor north of Osmer (Ann Arbor) and the old GR&I/PRR line from Cadillac to Petoskey. These were dispatched from the office at Owosso. Entire operation moved to the Great Lakes Central.

Wabash Railroad

Dispatched from Montpelier, OH. Delray to Montpelier.

Note:  Additional research is needed for many of these lines and miraid of other lines in Michigan.  If you have any additional research to contribute, please send it to This email address is being protected from spambots. You need JavaScript enabled to view it..
