Canadian Track for the Turn of the Century

Webmaster's note: Somehow, the printed version of this article has found its way into the great bit bucket. This is a slightly earlier version, which has not had the benefit of editing, or even spell-checking. In the interest of time, I am putting it up anyway.


The Prototype

Around 1899, the Canada Atlantic Railway upgraded its track to 76 pound rail laid on "almost" 3000 ties per mile from 50 pound laid on 2200 ties per mile [Bell, 1994]. Local accounts indicate that the ties were either untreated or treated with a light-coloured compound such as zinc. There were no tie plates, which is not unusual for the era [American Railway Engineering and Maintenance of Way Association. Proceedings of the Ninth Annual Convention of the American Railway Engineering and Maintenance of Way Assocition. Volume 9, ARE&MOWA, Chicago, 1908.].

Examination of photographs indicates that the rails were approximately 30 ft long, joined by four-bolt joint bars with the bolt heads all to the inside of the rail. An interesting feature of several Canadian railroads, and the Canada Atlantic in particular, is that the track crews went to some effort to ensure the joints in the rails were opposite one another; early in this century, staggered joints became the norm.

Ballast on the Canada Atlantic was nominally gravel. The AREA suggested that gravel should be large enough to be retained upon a number 10 screen (presumably 10 wires per inch) [ARE&MOWA. Proc. Tenth Ann. Conv. of the Am. Ry. Eng'g and Mtc of Way Assoc. Vol 10. ARE&MOWA, Chicago, 1909, p677-720]. However, photographs reveal that the ballast of the Canada Atlantic and its gravel pit consisted of a lot of sand.

The Model

It is difficult to improve on the appearance of modern flex track. Offerings from companies such as Railcraft include wood grained ties, tie plates and very fine spike detail. However, no flex track is appropriate for modelling the track of the Canada Atlantic. First, the tie plates belie the modern heritage, and second it is difficult to give the plastic ties the appearance of untreated wood.

The latter problem is easily solved by handlaying rail on wooden ties. However, that solution results either in spikes that are far too large, or spikes that are missing altogether. This article explores one method of detailing handlaid track.

Ties

To represent the untreated ties, I decided to use wooden ties. Railcraft full profile ties were glued directly on paper templates that I had laid out using a CAD program. These ties are a scale six by eight inches, by eight and a half feet long. This is possibly six scale inches too long, but for the purposes of the experiment, they were deemed sufficient. The ties are very rough, and could bear some sanding, especially on the sides where there is an obvious saw mark. However, after a couple of abortive attempts scraping my finger nails along a piece of sandpaper, I decided they were good enough. After all, the sides are mostly buried in ballast anyway.

Quite a few of the Canada Atlantic's ties were flat only on two sides, and these are poorly represented by the Railcraft ties. Perhaps one of the other arch-bar era modellers in the group will come up with a reasonable way to represent those ties so we can model the situations where the ties have not sunk into the ballast so much.

Ballast

So far, we have proceeded very much the way I always have, with the exception of the templates. Usually I ballast the track last, but this has not always been a successful strategy. Often I get all the ballast nicely pushed and prodded into place, only to have it float up and bond to the sides of the rail as soon as there is glue in the area. This time I wanted to experiment with some very fine ballast, and I knew that this material would have an even greater wanderlust than Woodland Scenics' crushed rock.

To obtain the very fine appearance of the Canada Atlantic's gravel ballast, I screened some local dirt through a typical sized screen, but found that it still looked too coarse. So I screened it again through a stainless steel etched screen (Tripart Modelling Mesh 104) that I purchased from the hobby shop. This had 0.3 mm round holes and the resulting dust makes somewhat believable sand.

Joint Bars.

While the ballast set, I started making up joint bars. With thirty foot rail sections, I used up an alarming number of these little pieces. As far as I know, there is no suitable joint bar for code 55 rail, and so, I started making my own from tiny pieces of plastic and Grandt Line nut bolt washer castings.

Normally, I apply NBWs by cutting them from the sprue just below the washer and dropping them in a drop of solvent at their final location. This operation is fine for a few bolts, but even on two feet of track, I needed to manoeuvre over sixty of these little tiddly-winks into position. After one joint bar was finished, I decided to find a better way.

In the end, I drilled four holes on six scale inch centres in a section of .010" x .100" plastic. The tails of the NBWs were inserted in these holes and drops of solvent were applied from behind. Once everything had set completely, the excess NBW tails were cut away with flush cutters, and the joint bars were trimmed to their final dimensions (2 scale feet by .030 inches) with a razor blade.

The inside halves of the joint bars were made up with plain pieces of .010" x .030" styrene. However, in retrospect, I wish they had the bolt head detail, which would not have been so hard to create.

The joint bars were glued to the rails at this point, and the assemblies were taped to a piece of cardboard and sprayed a rusty grimy browny grey colour. Anyone who has ever had to paint rail once it has been stuck to the ties will not need to ask about my reasons for painting the rail before laying it down. The cardboard nicely masked the underside of the rail so I would have a clean surface on which to spread the glue.

Laying the Rail

At last it was time to lay the rail. This I had planned to do using the Pliobond method. Pliobond is a contact cement that dries to a very strong, but flexible bond. It has been used by N-scalers for many years to bond their light rails to ties. However, it has never been used by me, and so I sent a quick e-mail to my friend Mike Davison whom I knew was experienced with this technique. His directions were as follows:

1) Bend the rail so that it lies in place without spikes.

2) Spread as much glue as possible onto the underside of the rail.

3) Wait until the Pliobond dries.

4) Position the rail, holding it in place with gauges if necessary.

5) Heat up the rail with a soldering iron, just enough to melt -- but not enough to burn -- the glue.

The last step is the important one. People who have no success with Pliobonding rail have probably burnt the glue. With my 25 Watt soldering iron, it took no time at all to melt the glue into the ties, creating a firm bond. Indeed, I found it necessary to keep the soldering iron moving constantly.

Spikes

Scale-sized spikes have been one of the stumbling blocks of detailed HO scale track for a long time. Dave Soderblom told us about the Grandt Line spikes in [Products of Interest, Proto:87 Journal Number 1]. According to Dave, these plastic castings have a spike head that is approximately 1.5 by 2 inches (40 by 50 mm). Modern-day real spikes are around 1.2 by 1.6 inches (30 x 40 mm) across or about .018 x .014 inches (0.45 x 0.35 mm) in HO scale. Thus the Grandt Line spikes are really quite good, particularly for heavy rail applications.

Spikes in period photographs, however, appear even smaller than those of today. In an effort to reproduce these tiny details, I devised the following method:

1) With a pin, poke a hole for the spike.

2) Push the end of a .010" (0.25 mm) rod into the hole.

3) Using a piece of plastic strip to gauge the height, cut the rod off .030" (0.75 mm) above the surface of the tie. For smaller spikes cut it lower; for larger ones, cut higher.

4) Using a slip of paper to shield the rail and the spike from the heat, bend the spike in toward the rail with a soldering iron.

5) Paint the spike head.

7) Spray the spike with dilute white glue to keep it in place.

Even with excellent light, this marvelously involved method seems to take about an hour or so for each foot of track. It is certainly not a worthwhile approach for background track! However, the resulting spikes are small and surprisingly uniform. Almost all of them came out as elongated discs, slightly overlapping the foot of the rail, and approximately 0.02" by 0.18" (0.5 x 0.46 mm) or 1.75" by 1.6" (44 x 40 mm) full size. They compare favourably in size to the spikes Railcraft code 55 flex track which are .03" by 1.8" (0.75 x 0.46 mm).

Conclusion

This painstaking construction method yields a beautiful representation of turn-of the century track. However, there are still some outstanding issues to address before I can proceed to lay the track for Pembroke. First and foremost, there are five turnouts on Pembroke, and each is planned to be fully detailed, including rail braces and switch rods. I will explore the construction of one of these in a future issue. Second, a method is needed to join two pieces of rail that is less obtrusive than the usual rail joiner.
