K Nearest Subway Station to Next Station in Feet: 14th Street Area & Williamsburg Brooklyn

In the map above, produced in ARCGIS, I  used a QGIS produced output of K-Nearest Neighbors from the Distance Matrix.   I joined that table to a previously produced map layer showing NYC subway stations.  I used the previous layer showing the new serial numbers.   I joined the layers together using ARCGIS.   The results are as follows: From top to bottom for each station:

Station Serial Number
Station Name
Nearest Station Serial Number
Shortest Distance in Feet

Thus for the 14th Street 1st Avenue Station "L Line"
Station Serial # 195
Station Label:  1 AV
Nearest Station to this station: 194  ( 3rd Avenue and 14 Street)
Distance in Feet (straight Line)    1424.2 Feet.

Another Example
Station Serial # 133
Station Name;  Astor Place
Nearest Station to this Station: 215 ( 8th Street NYU)
Distance in Feet: 443.466
