Setting The Stage

Planning staging isn’t an easy task. Particularly when you find out your expected 10-cars train length ends up being 20 cars. That was totally unexpected, but during the last week – after reading endlessly Mike Confalone’s Allagash Story Volume 3 – it became clear to me I had to seriously commit myself to understand rail traffic to improve the overall layout performance. I won’t go into details, but I did my homework and it helped me to better understand Murray Bay subdivision.

Since then, I found out cement traffic from Villeneuve wasn’t going very far. In fact, cement hoppers travelled only a mere 5 miles before reaching Quebec City Pier 53 where cement was transloaded on ships. Better, I finally understood the small spur branching out at D’Estimauville was used to handle cement traffic directly to Pier 53. In fact, this spur became redundant in the early 70s when they built the highway and CN modify Beauport Flats yard. At that time, cement traffic was reduced and 524/525 only operated as an extra. For our purpose, I’ll keep it on the layout because it is an interesting feature to operate, but also because it makes the track plan and staging easier to handle.

An early sketch of D'Estimauville simplified trackage without Beauport Flats spur.
To plan the required staging size, you need to know your largest train length. On Murray Bay Sub, the largest train will be train 524/525 to Villeneuve. At most, it has ten 50ft cars and ten 40ft hoppers, thus 135 inches. Add 2 locomotives (16 inches) and one caboose (6 inches) and you get a total of 157 inches. Round it to 13 feet which is quite a very long consist. That’s the length I need to completely hide the train in staging. Why? Because I find a train coming from “outside” the layout really makes you believe it is linked to the outside world. I used a few time “on layout” staging and wasn’t satisfied with that at all…

Having only 2 scheduled train to stage, two hidden tracks are needed. I recently explored the idea to hide an helix into the closet and have a staging deck under D’Estimauville. This is feasible, but requires a lot of job. Worst, it could eat up a lot of storage space under the layout. I’m not against the idea, but at this point, I feel going the KISS way is the best choice. Jérôme once proposed to hide staging on curved track into the closet and I choose to develop this idea.

Proposed staging developed from Jérôme's original idea.
The nice thing is that everything is on the same level and we don’t have to modify greatly the closet. In fact, when we rebuild that part, we already installed a shelf benchwork to support a future loop.
Since each staging track branch of from Murray Bay at different spots, they will spiral around each other. Rail cars drawers could also be installed into the closet, making it a nice place to stage trains without interfering with the layout itself.

Also, this track geometry helps us to hide nicely and realistically the tracks with scenery. Beauport Flats spur curves and disappears between two row of trees from Domaine Maizerets (a municipal park) just like the real thing. Murray Bay subdivision mainline and sidings disappear under Boulevard Henri-Bourassa overpass as per prototype. Both locations have a different treatment, making it easier to feel like trains are headed to two different places. Murray Bay siding is only a storage track for cars, engine or MoW. They were often found there on the prototype and I feel they help to create a second “scenic layer” in from of the backdrop hidden effectively the point where the main line punch through it.
