|CN 2026 is passing under the new concrete overpass.|
My layout is heavily inspired by the old grain elevator near Route Lagueux in St-Nicolas (east to Charny) on CN mainline on Quebec South Shore. At this very place is a typical exemple of a highway access road concrete overpass built in the early 60s when Quebec was developing its highway network.
|Basic shapes glued together and test fitted.|
I've always found it a nice locale when I was a kid and my father would drive us to a aunt living in the area. So I decided to make a replica of it to hide the staging area.
The prototype was measured with Google Earth help. Deck and piles are made out of 1/4" MDF. Lots of fun on the table saw! Well, in fact, it was more straight forward than I anticipated.
MDF parts were glued together with carpenter glue and illustration board was used to define the underside of transversal girders. They would be used as lost form when pouring plaster.
|Plaster set in place to fill the gaps.|
I finally used plaster of Paris to fill the gaps and get an even surface. The back of a saw was used to shape correctly the plaster. Some rough spots are there, but I'll keep them to represent crumbling concrete (eh! Quebec is famous for it's sh*tty concrete infrastructures and poorly built roads... looks like 400 years isn't enough to learn the lesson up there!!!). Joke aside, it will help to get a more realistic look. I often feel plastic kits and styrene lacks the texture to make believeable massive concrete structures.
