I did an article for the TTOS periodical on Plasticville kitbashing. You can buy parts
and loose buildings galore, and dirt cheap, with glue (I scrape old glue off and use epoxy for permanence), and did detailing and weathering. I wanted a number of stations that did not LOOK like the Plasticville station, and had a good time cutting and lenghtening various components, (walls, roofs, moving windows and doors around) to come up with a Y shaped one, a two story one, and several others, BUT I decided that all were, when compared with scale kit built O scale stations, S scale. I reduced a Lionel Rico station kit down to Plasticville size, also, but decided not go go with them. At the back of a layout, if trying to gain visual distance, they would work. Since just about everything in this hobby, definitely including empty boxes, is collectible, I was careful to avoid anything that looked mint, boxed or marbled (this last seems collectible in PV). If buying new...go wild.
Painting with flat colors, or even clear flat, greatly takes the plastic sheen off and
enhances the "realistic" appearance.
I had Plasticville on my childhood layout, and loved it...wanted and would have
bought more...it was an upgrade from cardboard Biltrite...but I have long since been to layout viewings at conventions that were literally acres of Plasticville, and, to me, they all look alike. And I have read too many MR's since my youth to want to use it out of the box today. (I have thought about doing another set of their stations, this time, 1/4 to 1/3 LARGER!) How about that common Plasticville
station lengthened to match the Lionel Rico kit, and made the correct height,
Grandtline doors and windows installed, etc. Should be, as were my kitbashed
small ones, worth a couple of double takes.
