The blog has been quiet for a while as other (homefront) projects have taken over. Despite that, I was able to chip away a few minutes here and there to work on a (HO scale) track plan starting at the south end and working north:
1972 track diagram with the exception of spot #335 on the far left:
The grid shown on the plan uses 12" squares which means that the left half is 30" wide. However, I expect to build this as a standalone peninsula without backdrops. With it accessible from all sides, I don't think the width will be a problem.
This is the first (public) draft -- following nine or so tweaks and rewrites -- and while writing about it now, I noticed that the left-most "module" is more compressed in real distance compared to the other two. This ends up shortchanging the spots along Terrace St at the top (#340, #342, and #348).
PS> I will have to confess that while reading blogs I follow and reminiscing about a previous operating experience and an O-scale switching layout, I was tempted to switch scales. I'd have to go P:48 if I did and I found myself quickly stuck trying to determine availability of period (1970s) freight cars. Do the P:48 modelers accept the slightly oversize equipment as long as the gaudy wheelsets are changed out? Anyway, that was a dangerous diversion and I'd better stick to what I know: HO scale. Though I will dabble with some of the P:87 aspects to enhance track detail.
