Vernon River / Murray Harbour Subdivision traffic analysis [PT:2 Researching Traffic Amounts and Crunching the Numbers]

7751 on Murray Harbour Sub CN002589
44 Tonner #7751 leads a mixed train on the Murray Harbour Subdivision. #7751 was renumbered #2 June 1956. Photographer unknown. CSTM Collection (#CN002589)

In my previous post I used newspaper archives to determine and describe the types of traffic I thought Vernon River would normally see.

My goal is now to not only determine the amount of freight traffic Vernon River would see but to also determine the average train length, loads and percentage of originating vs terminating traffic on the Murray Harbor subdivision as a whole. Having these statistics will allow me to accurately model the car movement both through and at Vernon River.

This info is important for a few reasons, but mainly I need to be able to:

  • Determine in general terms the amount of switching moves per operating session
  • Determine to the average train length through Vernon River
  • Determine the usual ratio of originating to terminating cars
  • Use the above information to figure out how long the single track staging cassette will need to be on each side of the layout.

With the new Drive-By Truckers record on in the background, into the rabbit hole I went.

In my files I found a summary written by Shawn Naylor of a freight report CN completed in the early 1960s. Apparently this report was prepared to propose reductions in PEI’s rail service. In the report CN used carload data from the mid to late 1950s which makes it super conveniently accurate for my layout’s era.

Below I’ve created a spreadsheet of carload data as it applies to the Lake Verde, Vernon [Loop] and Murray Harbor subdivisions from this summary (the same mixed train #240N / #209S served these subdivisions.)

If you’re not familiar with island railroading it’s important to note that “Vernon” and “Vernon River” are two different locations. I’ve marked Vernon with [Loop] to make it less confusing.

Using the numbers on the chart it would be fair to say the average train could include around five freight cars- a pretty low key operation. Most photos I’ve seen reinforce this, showing on average zero – three freight cars plus the baggage and coach car. [With a train so small I should be able to get away with a 5ft staging cassette on each side of the layout]. Obviously not all of these cars would be destined for Vernon River. In fact, it probably wasn’t a daily occurrence that anything would even be switched there. For the sake of fun, my layout will only operate on days where there is an originating or terminating load for Vernon River.

Knowing the average train length I now need to know what types of freight we’d see on that train. Naylor’s summary includes traffic types for the Murray Harbor, Lake Verde and Vernon [Loop] subdivisions but the figures are irrevocably lumped together with the Montague and Georgetown subdivisons. I can live with that though- the Montague and Georgetown subdivisions would have seen pretty similar types of traffic. It shouldn’t distort our reality too much.

1958 Originating vs Terminating Carloads: Murray Harbor, Vernon [Loop] & Lake Verde Subdivisions:

  • Originating Carloads: 67%
  • Terminating Carloads: 33%

1958 Originating Carloads: Murray Harbor, Vernon [Loop], Lake Verde, Montague and Georgetown Subdivisions:

  • Potatoes: 57%
  • Turnips: 33%
  • Other: 9%
  • Livestock: 1% (Aprox 13 carloads per year)

1958 Terminating Carloads: Murray Harbor, Vernon [Loop], Lake Verde, Montague and Georgetown Subdivisions:

  • Other: 54%
  • Sand and Gravel: 27%
  • Fertilizer: 13%
  • Coal and Coke: 3% (Aprox 30 carloads per year)
  • Animal Feed: 2% (Aprox 27 carloads per year)
  • Petrol Products: 1% (Aprox 9 carloads per year)

In Naylor’s summary is it said that a contributing factor to PEI’s high operating costs was the need to use different cars for originating and terminating traffic; cars used to import things to the Island tended to leave empty. As such, local moves will range from very rare to non-existent on this layout.

With these statistics I now have a great foundation to base my layouts operations around. Even though I’m only modelling a single village, I think its important to consider the subdivision as a whole in order to serve my chosen village accurately. 

Now I just need to figure out how to work these averages and percentages into a car card system…

Vernon River / Murray Harbor subdivision freight traffic analysis [PT. 1 Researching Traffic Types]

With a prototype chosen it was time to dive a little further into my research.

My first goal was to figure out the types of freight traffic the village would see in a broad sense and not just my chosen era; after having that information I could then, through logic and evidence, figure out what would be applicable to my era.

One of the primary tools for the research job was islandnewspapers.ca. – “a fully-searchable online archive of PEI’s main newspaper of record, The Guardian, from 1890 to 1957.” This archive along with a document by Shawn Naylor that Steve Hunter passed to me a few years ago provided me with a wealth of information.

June 11 1948 / Guardian of the Gulf
April 23 1948 – Guardian of the Gulf
April 15 1948 / Guardian of the Gulf
July 25 1947 / Guardian of the Gulf
December 10 1945 / Guardian of the Gulf
September 11 1930 / Charlottetown Guardian
March 22 1921 / Charlottetown Guardian
November 18 1919 / Charlottetown Guardian
October 22 1917 / Charlottetown Guardian

What I found was that Vernon River received quite a few different commodities ranging from general merchandise to mussel mud. Its main exports would have been produce (potatoes likely being the majority of this) and livestock (mainly hogs). 

I have compiled the following list of inbound and outbound traffic. Everything listed is based upon direct evidence (unless marked with a “*” or “**”) found in newspaper archives or in Naylor’s document. 

  • Outbound Traffic:
    • Produce (Potatoes, Turnips and other crops)
    • Livestock (mainly hogs but also cattle)
    • Finished Wood (*) (not likely in my era)
  • Inbound Traffic:
    • Animal Feed
    • Limestone
    • Fertilizer
    • Bulk Oats
    • Barley
    • Bulk Wheat
    • Fuel (**) (would oil and gasoline be pumped from tank cars into trucks to supply farmers with fuel?)
    • Coal (OCS and revenue)
    • Ties (OCS)
    • Mussel Mud (not likely in my era)

(*) Outbound loads of finished wood is a assumption at this point and only that. This is based on the existence of a saw mill about half a km away from the station. While I have not found any evidence to back up this assumption I don’t think it would be much of a stretch to consider them using the public siding to ship finished wood at some point. I have not found much information on the saw mill and it’s hard to tell in my air photos if it exists in a operational capacity in my era. 
(**) There is no evidence I have found of fuel being received at Vernon River. Would it be possible that fuel would be pumped from a tank car into a truck to deliver to farmers? The farmers had to get it somehow and even still by the late 1950s not all of the roads east of Charlottetown had been paved. I am genuinely not sure how this worked.

Based upon the list above its easy to imagine the types of rolling stock the village would have received, namely lots of reefers, boxcars and stock cars. 

Next time I will delve into the research of the daily amount of carloads both originating and terminating (along with their types) to try to get a sense of what a switching job at Vernon River consisted of.
