From the HBS Real Estate Report, 1955 in collection of author.
Enlarged view of HBS Yard
This track plan is kind of buried in the HBS Report, so I thought I would post here for Bruce, Mark and all the folks following their Hoboken Shore layout construction at Railroad Line Forums. The enlarged view shows the location of the double slip switches in the conversation. There is a nice post on page three of that thread which has images of a brochure probably from the 60s.
