The Norfolk Southern passenger speed reduces from 70 mph at milepost 156.5 to 50 mph at milepost 153.9.
The at milepost 153.5 the speed is further reduced to 40 mph accelerating to 65 mph by milepost 152.5
The proposed realignment in yellow in the above two images would use 1 degree curvature in order to have a line with a potential 110 mph allowable speed .
An alternative realignment could be a combination of that in yellow and orange above. It isolates a higher speed line from the town of Mifflin exploiting the Juniata River for a new right of way separated from the town.
