Sheldon Junction Bridge

Richford Local crossing Missisquoi River, John Krause photo
It's been a number of years since I've bought bridge kits. The scenic highlight of the new layout, as on the prototype, will be the crossing of the Missisquoi River at Sheldon Junction. The railroad crossed the river on three through truss bridges. At least it was three until June 29, 1984. On that date the last four cars on a B&M/CP detour train derailed, and in the process destroyed one of the spans beyond repair.

That derailment was really the end of the Richford branch as a railroad line - as the tracks were abandoned east of that point and the damaged span removed. 
I've seen photos of the bridge - such as John Krause's photo above and Ian Stronach's photo shown to the right. 
I figured the bridge looks close enough to the Central Valley Truss bridge that I'd simply order three of them and build them up. 
But in the years since I've bought a bridge - or seriously looked at bridge kits - Central Valley has added to their product line by offering their "classic" bridge as an Eastern Gusseted or Punch Plate bridge. Great, knowing my luck I'll pick one of the three, guess wrong and find out only after it's installed on the railroad!
Google to the rescue. 
Even the railroad tracks are long gone the Richford Branch right-of-way is still there - as a bike trail. And Google Maps
Google Street View of the Sheldon Springs bridge. 
offers a street view from the bike trail taken from the bridge. 

A few quick clicks and I was able to determine the original Central Valley Pratt Truss bridge is the closest to the prototype. I was also able to use the map
to determine the length of the span - the Central Valley bridge is 150 feet long, meaning three spans measure 450 feet. Google Maps indicates the river is about 370 feet or so across - but that's today's bike trail - as shown in the John Krause photo above, the abutments weren't located on the edge of the river, meaning 450 feet or so should be close enough, and ought to make for an impressive scene. 
Naturally, guess which version was nowhere to be found at Timomium last weekend!

Crafting a Strategy

Although we’re not completely “moved in” to the new house (read: the cars are still in the driveway as the garage is plenty full of boxes) we are almost moved in – which means I’m looking forward to getting started on the new layout – hopefully at some point this summer. With that in mind, I’ve been thinking through how to approach building the layout.
The first possible approach is to build all the benchwork, lay track (even using something like Atlas code 83 track and turnouts as a temporary track), wire up the DCC system and be railroading. At that point I can go back and add more detailed track, scenery, structures and the like one scene at a time. 
One of my favorite model railroad design books is John Armstrong’s “Creative Layout Design” that I got when it was first published in 1978. While the cover
Can a valid approach to layout
 construction, be found
in one of the more
obscure plans in this classic? 
and interior layout of the book screams “1970s”!!, and some of the plans show the too-tight aisles and stacked track of many of Armstrong’s plans, the text and reasoning behind the designs is still valid – and the layout designs in this book were among John’s most creative and innovative.

One of the most unusual designs is for a large scale indoor layout based on the Maine Central’s interchange with a two-foot railroad. What was interesting and relevant to the topic of this blog post is the way John suggested approaching the project. 
He included a table in the book that showed how someone could approach this particular project that required virtually everything be scratchbuilt. First build a section of layout, then build a narrow gauge locomotive, a combine, and several flat cars… once that was done build the connecting MEC standard gauge track, followed by an MEC Ten Wheeler… that sort of thing.
So how would that look on my Richford project? 

The trackplan highlights how I’d divide the layout construction into three phases – the first would be the Richford peninsula proper, with enough benchwork on either end of the base of the peninsula to firmly secure it in place and allow for a temporary staging track on both ends. Why start with Richford? 
The answer in my case is that, with the exception of the plywood plant and perhaps the Richford depot, I have structures that I can use here. 
Phase II would continue the benchwork around the walls (not shown is there may be a Phase IIa, Phase IIb approach – where I’d complete “Enosburg Falls” before completing Sheldon Junction, or some such. 
Phase III would see the Sheldon Springs peninsula added. 

Taking some inspiration from the approach outlined in Creative Layout Design, I’d plan on completing other other projects to the list. For example, I have two CV brass N-5-a 2-8-0s. Both of them need decoders and a paint job. With my prior layout the work on the layout took priority over all else, meaning I was using “stand in” locomotives awaiting a chance to “get to” the correct locomotives. Likewise, I had a lot of unweathered, out of the box freight cars to “fill out” the trains – with unbuilt resin kits in sitting in their boxes. 

Here's a tabular view of how this might look for Phase I: 

Rolling Stock
Install track lighting fixtures

Benchwork complete for peninsula, with temporary staging on both ends.


At least 32 “completed” freight cars appropriate for layout*

Track laid, feeders installed, and switch frogs powered to include:
1 custom curved turnout
7 LH no 6 turnouts
4 RH no. 6 turnouts

Install DCC system and wiring to include turntable controller


Install existing structures – freight house, warehouse, mockups for others

Base scenery complete

Paint, weather, and install decoder in one N-5-a 2-8-0

* This particular task is already complete as I have far more than 32 “completed” cars! ("Completed" means mechanically tuned, detailed including complete underbody, and weathered). The quantity of 32 is based on the total track capacity of Richford, divided by 50% - with one staged 14 car train. Thirty two cars is too many cars on the Phase I layout at once, so some of the 32 would serve to add variety to trains even at an early stage. 

Once I reach “Task 8” in the table above I can either proceed to start Phase II or refine and “tweak” Phase I perhaps by adding more details to the scenery, scratchbuilding the structures to replace the mockups, build more freight cars and the like.
Of course one could combine both approaches shown – build all the benchwork, lay temporary track, and then go through a step-by-step approach for each scene as shown above.
My goal here is not to create Gandtt charts, schedules and the like but instead to develop something of a methodical approach – otherwise it can become far too easy to either get bogged down in the constant slog of a huge undertaking, or end up jumping from one project to another in such a manner that nothing gets done.
