Newton has only 19 thousand people. So you are telling me that 3 times the population of Newton will use this train and transfer in the middle of the night to the SWC or whatever.
According to Amtrak, 13,890 people use that station now for just the two Chief stops each morning. That's more than any other Amtrak station in Kansas. Generally speaking, these are just people coming from the vicinity of Newton.
Taking into account new connecting traffic at Newton, new O&D traffic for all of the new Heartland Flyer stations, and new connecting traffic at FTW, it's not unbelievable that the route could add a pretty hefty number of riders.
