The Belton Grandview & Kansas City Railroad's line is a short section of what was once the St. Louis and San Francisco's Blair Line, also 
known as the High Line. The line was built in the later part of the 1800's and saw service up until the mid 1980's. A detailed history of the railroads that make up line, and how they came about is available.
The line originally started at the old Grand Central Station at 2nd and Wyandotte, this was Milepole 0. It left the Station and passed through Knoche Junction at mile post 3.8, continued on through several stations including Swope Park, Milepole 14.0, Holmes; Milepole 18.1, Grandview; Milepole 22.7 and through Belton at Milepole 28.2. The line continued on to Peculiar; Milepole 36.7, Harrisonville; Milepole 45.2, East Lynne; Milepole 51.8, Gunn City; Milepole 56.1 and on south to Henry County, Clinton, Osceola, Bolivar and finally to Springfield.
Our track starts on the north side of 155th St (also known as County Line Rd. the border between Cass and Jackson Counties). Just a few hundred feet north of Milepole 26. It continues on down to Milepole 28 right around 58 Highway, and the depot at Milepole 28.2. This north end of our line is not currently in service for passengers. Our trip runs south (southeast) from the depot, through Belton Park crossing Mullen Road and continuing on to parallel US Highway 71 for about a quarter of a mile before coming to an end at Cambridge Road.
As you ride our line south, you'll notice Milepole 29, at the south of Belton Park, and Milepole 30 near the bottom of a long hill just before the line turns to parallel US 71.
The line from East Lynne to Springfield was cut in 1979 when the Truman Dam was built. The line was not profitable enough to justify building a bypass or bridges for the areas that would be flooded and so it was abandoned. The remaining line was operated by the Burlington Northern until 1986 when it too was abandoned. The line north of 155th street is owned by the Kansas City Southern Railway, and is used to switch industries that still receive railcars from the KCS mainline in Grandview. An example of this can be seen at 150 Highway just west of US 71, where a plastic bag company receives covered hoppers of plastic pellets.
A more detailed history of the origins of this line is available as well.
