History
Construction of what is now the 124-mile Plymouth Subdivision was attempted in the 1860s by a succession of short-lived and undercapitalized railroad companies, including the
Detroit and Howell Railroad (organized 1864), the
Ionia and Lansing Railroad (organized 1865), the
Howell and Lansing Railroad The Howell and Lansing Railroad is a defunct railroad which proposed to construct a railway line between Howell and Lansing in central Michigan

(organized 1868), and the
Detroit, Howell and Lansing Railroad (created by merger 1870). Principal construction on the Lansing–Detroit segment was completed by the

The Detroit, Lansing and Lake Michigan Railroad (DL&LM) is a defunct railroad which built and operated the first rail line between Detroit and the state capital Lansing. Though the corporation was short-lived, much of the route it placed in servic ...
(created by merger 1871), with operations commencing on August 31, 1871.
In 1896 control of this east–west mainline through the state capital passed to the
Detroit, Grand Rapids and Western Railroad (DGR&W), and subsequently by merger to the
Pere Marquette Railroad (later Railway) in 1900. Though never among the most profitable railroads, the Pere Marquette persevered until it merged with the
Chesapeake and Ohio Railroad (C&O) in 1947. The C&O became part of the
Chessie System in 1972, and was absorbed into

Route
For most of its length the Plymouth Subdivision crosses gently rolling farm and forested terrain, passing through small towns and the state capital. The high point east of Lansing is 1000.4 feet above sea level at Canwell (CH 51), and the low point 830.6 feet at Beck (CH 27), for an elevation change of 169.8 feet. The steepest grade in this segment is 1.2% west of Canwell. The high point west of Lansing is 883.1 feet at Saddlebag Road/M-66(CH 116), and the low point is 690.7 feet at the Thornapple River (CH 139), for an elevation change of 192.4 feet. The steepest grade west of Lansing is 1.8% in the vicinity of Jordan Lake Avenue on the eastern side of the town of Lake Odessa. Despite the relatively modest grades, trains occasionally stall climbing Salem Hill west of Plymouth and coming east out of the
Thornapple River valley.
The route of the Plymouth Subdivision has the following waypoints:
* Plymouth Diamond – CH 24.5 – the Plymouth Subdivision joins the CSX Detroit Subdivision and is crossed by the dual track north–south
CSX Saginaw Subdivision

Traffic
When it was the Pere Marquette's primary route and the mainline between Michigan's two largest cities, the Plymouth Subdivision's rails were bustling with traffic. Even as late as the mid-1980s, in the first years under CSX, the line saw a dozen CSX and four
Soo Line freights daily, in addition to numerous locals and commodity trains. Over time, however, much of that traffic moved southward, using
Norfolk Southern's tracks from Detroit to Chicago via Butler, Indiana and CSX's own B&O route between Toledo and Chicago through
Garrett, Indiana. As of June 2011, only two pairs of symboled trains are regularly seen on the Plymouth Subdivision, giving it the character of a branch line rather than a mainline. Current and former trains include:
Current trains:
(East of Lansing Ensel Yard)
* CSX L302 - Rougemere (Detroit Sub) ''to'' Grand Rapids. Mixed manifest between Rougemere and Grand Rapids, stops at Lansing Ensel Yard. Currently running daily.
* CSX L303 - Grand Rapids ''to'' Rougemere. Mixed manifest between Grand Rapids and Rougemere, stops at Ensel Yard. Currently running daily.
* CSX L305 - Lansing Ensel ''to'' Howell* - Local, services east of Lansing to the GLC interchange at Ann Pere, sometimes works Peaker Services in South Lyon.
Locals operating west from Plymouth Yard, east and west from Ensel Yard, and east from Wyoming Yard in Grand Rapids switch customers along this line. A nightly local (CSX L304) services customers between Ensel and Lake Odessa. A daily local (CSX L305)services customers between Ensel and South Lyon. L305 also shuttles cars from Ensel to interchange with the GLC railroad at the AnnPere diamond interchange track near Howell. A daily yard job train (CSX Y106) serves customers between Wyoming yard and the Elmdale siding.
Full and empty commodity trains (grain/coal/lime/potash/stone) operate over the Plymouth Subdivision on an irregular basis.
Former trains:
* CSX Q326- Chicago-Grand Rapids-Detroit (Now a Chicago-Grand Rapids run)

Signaling and Dispatching
All CSX operations in Michigan, including the Plymouth Subdivision, are managed by dispatchers in Jacksonville, Florida
The Plymouth Subdivision is
CTC signaled from Plymouth diamond west to Lansing Ensel yard.
A 30-mile portion west of Lansing Ensel yard to Lake Odessa is track warrant controlled by CSX form EC1 authority. The track warrant section is protected by automatic block signals in addition to the track warrants. CTC signals resume at Lake Odessa and continue west to Grand Rapids Wyoming yard.
The track warrant controlled section previously consisted of five
ABS DTC controlled blocks (Cash, Ledge, Field, Jordan, and Lako). The DTC blocks were discontinued in favor of the form EC-1 authorities during the summer of 2011.
Passenger Service
There is no passenger service on the Plymouth Subdivision as of 2017, but surviving depot buildings in towns along its route are reminders of a different era.

In 1946, the Pere Marquette introduced the nation's first post-war lightweight
streamlined passenger trains, operating between

Lansing. The local had a scheduled trip of 3:00 due to additional stops in Brighton, Howell, Fowlerville, Williamston, Grand Ledge and Lake Odessa. The service was continued by the Chesapeake & Ohio under the ''Pere Marquette'' name following the 1947 merger. The final passenger train ran on the Detroit-Grand Rapids route on April 30, 1971.
The Union Depot at Michigan Avenue, just blocks from the state Capitol, survives and was Clara's Lansing Station restaurant until the restaurant closed in 2016. The Williamston Depot was moved a half mile to Grand River Avenue in 1979, where it now houses a museum and the city Chamber of Commerce.
The Fowlerville Depot is still owned by the Pere Marquette successor
CSX and used as a base for track maintenance crews. As in Williamston, the Lake Odessa Depot survived through relocation and repurposing as a museum.
