ConRail 6583 (a)

The sun hasn't risen far enough to get all the way into CP 123 at 06:53 as TV8B slithers into the new interlocking in Chester, MA. This location had been the eastern limit of Rule 291 signaling over Washington hill when the route was still double track/ABS. Note the naked signal masts in the middle distance which once held the Automatic Block signals.
