The company's executive and administrative offices are located in downtown Indianapolis, with a classification yard, shops and main transloading facility located on the city's near south side at the Senate Avenue Terminal (between I-70 and the Indianapolis Union Railway's Belt Line). Long abandoned and now removed was a connection to Union Station, which once ran between Senate Avenue (originally known as Mississippi Street) and Missouri Street north from this terminal's location through the present-day site of Lucas Oil Stadium. A remnant of this connection can still be noted today in the unusual height of I-70's overpass above West and Missouri streets, which when the freeway was built in the early 1970s had to also pass over this then still active rail line.
Additional INRD classification yards are located at Palestine, Illinois, and Jasonville, Indiana. The latter facility, known as Hiawatha (in tribute to original owner Milwaukee Road's crack passenger trains) is also home to the main locomotive servicing facility. The company was formed in 1986 by entrepreneur Thomas Hoback, who remains president and chief executive officer. CSX Transportation now owns a majority interest in the parent company. On March 18, 2009, the railroad announced that it would build a new 5.2 mile rail spur in Sullivan County, Indiana, for the new Bear Run coal mine. Bear Run is being developed by Peabody Coal and is expected to produce more than 8 millions tons annually.
The Soo Line Railroad abandoned a section of the line between Bedford and Seymour, Indiana, as soon as they took over the Milwaukee Road in 1986. The Canadian Pacific Railway operated on the Chicago-Bedford line from their acquisition of the Soo Line until 2006, when they spun it off to the Indiana Rail Road company. On December 18, 2009, it was decided to cut the southern part of that line even more, as they are abandoning between Bedford and Crane, a total distance of 21.15 miles.
