Kansas City (25th Street) to Olathe

From the flat crossing with the former Santa Fe main line, the junction with the connector from Union Station trailing in on the east side, the flyover carrying a connector to the Hi-Line overhead, the connector from the former Santa Fe to the west trailing in on the west side, and the junction with the line off that last flyover, trailing in on the east side, all at 25th Street (MP 1.6 on the Fort Scott line), Two Main Tracks, CTC, resume, with the former Frisco line heading southwest, speed limit 10 mph, past the border between Missouri and Kansas and the final junction, where the line off that last flyover has finished trailing in and a spur heads away south-southwest (i.e., on the east side), at 29th Street (MP 2.1), where the speed limit has risen to 20 mph, 30th Street (MP 2.2), where tracks separate, passing either side of the former M-K-T Glen Park Yard, and then coming back together again.

The line passes Rosedale (MP 3.9), and a location where the erstwhile Kansas City, Lawrence & Topeka Electric Railroad (interurban) once crossed, turning west-southwest past crossovers at Bravo (MP 5.6), where the speed limit has risen to 30 mph, south-southwest past Merriam (on the interurban line before it's route turns away west), southwest, south-southwest, southwest past Lenexa (MP 13.9), where the speed limit has risen to 50 mph and the right-of-way of the erstwhile Missouri & Kansas interurban comes alongside to the southeast, just west of due south past crossovers at Charlie (MP 16.5), south-southwest at Lackmans (on the interurban) past Pleasant View (on the interurban), and just west of due south past a former crossing with that erstwhile interurban to Olathe (MP 20.5), where the speed limit has risen to 60 mph, single track, CTC, starts, and a connector from a former Santa Fe line, providing access from Argentine Yard, trails in on the west side.
