A little more progress.
After building the support post assemblies for the roof trusses, I installed them temporarily and marked the location of the posts on the floor. The segments of the styrene floor were each then split in two at their mid-point, and the half markings on each were cut-out to accept the base of the posts. All of the floor sections were then brush painted, including those to be placed between the rails.
Next, I used a cheap 1/2" brush to apply lacquer thinner to the bottom of each segment, immediately following that with a 2" brush to apply the gelled contact cement. Following that, the balsa sub-floor got a coat of contact cement and all were left for 20 minutes-or-so, until the excess solvent had evapourated. Meanwhile, the half inch brush was used to apply a coat of lacquer thinner to the between-the-rails pieces of styrene and to the tie-tops where they were to be placed, and each of these pieces was set into place. After that, it was a simple matter to carefully place each segment into position and press it firmly to the subfloor.
Here's the floor in place, along with the roof truss support posts:

...and with a post assembly removed:

...and finally, a closer look. The line connecting the holes is the cut made down the centre of each floor segment, while those running crosswise are simply scribed lines to represent expansion joints. Weathering will be added after the interior walls have been painted:
