The last WB 422 leaves Linden at 8 PM and gets to Northbrook Court at 9:23 PM. The bus then goes to Golf Mill and turns into a 270 that leaves Golf Mill at 10:20 PM and arrives at Jefferson Park at 10:44 PM. It leaves Jefferson Park at 10:50 PM and arrives at Golf Mill at 11:14 PM.
I'm not sure if this means anything, but yesterday (Sunday) a northwest division driver was driving the 412 route. One of the Niles drivers was with him.
