Usage and Restrictions on 6 Axle Power on the ACR

Posted on December 15, 2015 by Chris van der Heide

In 1971 the ACR received what was to be their first order of modern, “second generation” diesel locomotives. In a marked departure from the smaller four axle 1500 and 1750 HP GP7 and GP9 units that comprised the motive power fleet at the time, the ACR ordered a trio of 3000 HP, six-axle SD40 locomotives from General Motors Diesel Division. This order was followed up two years later with six SD40-2 units in 1973.

The large size and weight of these modern units, combined with the long rigid wheelbase of the three-axle trucks underneath raised some concerns about increased track wear and maintenance as a result of their use – similar concerns had largely restricted the use of the ACR’s largest steam locomotives, a pair of rather heavy 2-10-2 (most of the ACR’s freight engines were of a 2-8-2 wheel arrangement). However, unlike the steamers, which were just a little too big for the railway, the SD40 and SD40-2 units were massively successful in hauling heavy ore trains between Wawa and Steelton yard, so these concerns were muted or just chalked up to the cost of doing business.

This is not to say that the big units didn’t have certain restrictions placed on them. The employee’s timetables list numerous special speed restrictions when the SD40 type units are used in a diesel consist, mainly in areas with sharp curvatures. In many places these restrictions are 5 to 10 MPH lower than the standard freight speed limits for those zones, and speeds in passing sidings was restricted to a maximum of 12 MPH (where the normal legal maximum for Restricted or Slow speed was 15 MPH).

Additionally, while no prohibition exists in the timetable, most sources tend to suggest that the use of the larger units was discouraged north of Hawk Junction – particularly north of Oba where the mainline was mostly 80-85lb rail, much of it original from 1912, so train nos. 5 and 6 would typically be run with smaller 4-axle power, with the big SD40s earning their keep hauling tonnage between Steelton and Hawk Junction, and on the Michipicoten branch ore trains.

Interestingly, today CN runs freights on the line up into Hearst with even larger typical modern power like SD70 type locomotives, although I’m not sure if the rails have been materially upgraded. Probably just significantly speed restricted.

Passenger Operations

Regular Service

Regular passenger service on the ACR was provided by train nos. 1 and 2 from Sault Ste. Marie to Hearst (and vice versa).

In the 1980 timetable, no. 1 was scheduled to depart Sault Ste. Marie at 9:30 am daily except Mondays (with no. 2 therefore running daily except Tuesdays) in the summer timetable, and only Fridays through Sundays (Saturday to Monday for no. 2) an hour earlier at 8:30 am in the fall/winter timetable.

If you turn back the clock a bit to the 1950s-1960s, passenger service was also included on the Michipicoten subdivision, and nos. 1 and 2 were actually daily excluding Sundays between Sault Ste. Marie and Michipicoten, connecting with trains 3 and 4 to/from Hearst at Hawk Junction. (Although in the late 1940s to early 1950s, three days a week this ran instead as Mixed (freight and passenger) trains 5 and 6. If you go far enough back in history, all passenger service was in mixed trains.) Passenger service on the branch was discontinued in the mid 1960s when Trans-Canada Highway 17 was completed through the area.

In more current times, CN continued to operate the regular passenger service (as trains P631 and P632) until early 2015, when for funding and political reasons the service was undertaken by a new operator (Railmark) which unfortunately – again, due to financial and political complications – was not successful and passenger service was terminated in July of 2015. As of this writing, local stakeholder groups are searching for and negotiating with potential new operators to try to save the service.

Tour Trains

In the 1950s, recognizing the scenic beauty of the Canyon and the tourist potential, the Algoma Central Railway established the privately owned Agawa Canyon Park and developed the location as a destination for a day trip tour out of Sault Ste. Marie on the “Agawa Canyon Tour Train”.

Tour train coaches dropped off by no. 1 at Canyon, July 3, 1972. R.J. Schwenk photo in my collection.

Some of the older coaches were upgraded with modified steps for easy de-training of passengers at the siding and service started out with regular train no. 1 dropping off a dining car and a coach or two in the siding to be picked up later by the southbound no. 2. This service grew in popularity throughout the 1960s with more and more cars being regularly set off in the siding at Canyon. By the early 1970s so many cars were being used in the Agawa Canyon Tour Train service that an extra train was run to exclusively handle the tour cars for Canyon. By the mid 1970s, it was permanently added as a regular daily train (nos. 3 and 4) in the summer timetable. Also from 1969 to 1974 “new” passenger cars were acquired to expand and replace the existing fleet, with coaches, baggage cars and dining cars acquired secondhand from such roads as Canadian Pacific, Central of Georgia, Southern Pacific, Santa Fe, Illinois Central, Union Pacific, and Denver & Rio Grande Western.

Equipment for the tour train service was upgraded again in the early 1990s with cars acquired from VIA Rail, and most recently in 2009 with the purchase of the Rio Grande Ski Train from Denver, Colorado. The Agawa Canyon Tour train still operates on a daily basis during the summer as CN P633 (for the entire round trip).

The long term future of the train is however uncertain as CN has been indicating they are not interesting in being in the passenger business. The original plan when Railmark assumed operation of the regular passenger service was for them to eventually operate the tour train as well; with the new search for another replacement operator, the idea as I understand it would again be to have that operator take control of all passenger service.

Somewhere around the late 1970s the railway also began running a weekend-only fall/winter version of the tour train service, with tour coaches being exchanged by regular trains no. 1 and 2 at Eton, without the stopover at Canyon park. In the 1990s and early 2000s the “Snow Train” ran as a separate train in its own right, still running through the entirety of the canyon and turning at Eton. This train has not run in several years now.

Paper traffic on the ACR

Posted on December 8, 2015 by Chris van der Heide

The primary source of paper traffic on the ACR was of course the old St. Marys Paper mill in Sault Ste. Marie. The original pulp mill dates back to the 1890s, and through a couple of name changes and significant expansions over the years, lasted until 2007 when the mill was shut down for good. The mill buildings, except for surviving parts of the original 1890 mill have since been demolished.

Despite having exclusive access to serve the paper mill, the Algoma Central rostered no boxcars for this service. Instead, as pretty much all of the mill’s output was exported south to the US, empty cars were provided by Canadian Pacific and SOO Line, and later primarily by Wisconsin Central.

St. Marys performed their own in-plant switching with their own engine, exchanging cars with the Algoma Central via several interchange tracks at the north west end of the property. ACR yard jobs would then accordingly deliver the cars to the CP/SOO interchange tracks.

In addition to the St. Marys mill in Sault Ste. Marie, additional paper traffic would also travel over the ACR from mills on the CN at Kapuskasing and Smooth Rock Falls and the Ontario Northland at Iroquois Falls bound for mid-west US destinations. Any westbound traffic that might have come these locations for central Canada or the west coast may have also traveled over the ACR from Hearst to Oba to continue westward on the CN main line.

CN Operations at Hearst

Posted on December 4, 2015 by Chris van der Heide

Hearst was the Algoma Central’s northern terminus and connection to the Canadian National Railway. For yard, station and other facilities the ACR shared with CN.

The ACR wye and connection to the CN main was just to the west of Hearst yard, and any movements on the CN main from Hearst Junction to Hearst would have to be made under the CN dispatcher’s authority. Conversely, if CN needed to turn some equipment, movements over the wye required the ACR dispatcher’s authority.

Equipment Restrictions

When the ACR first connected to Hearst in 1914, Hearst was a division point on the transcontinental mainline of the National Transcontinental Railway. However when the NTR became part of the Canadian National Railways in the early 1920s, this became a secondary line to the ex Canadian Northern Railway main line (crossed by the ACR at Oba) which is still CN’s primary transcontinental route today. As such, this line languished and was never maintained to the same standard as a more major route.

The Pagwa subdivision between Hearst and Nakina featured exceptionally light rail – often less than 80 lbs/yard – that had never been upgraded since the steam era and probably in these late years a fair bit of deferred maintenance in general. This line was *severely* restricted as to the weight and types of equipment that could run over it, with the heaviest diesel locomotive permitted on the line being an SW1200RS. (CN 1387-1395 are known to be in Hearst in the late 1970s.) Cars with greater than 177,000 lbs (88 tons) *gross* weight required special handling, and during the months of May-June for the spring thaw cars exceeding 142,000 lbs (71 tons) gross weight are banned west of Calstock.

East of Hearst is better, but still light rail. GP9s could operate west of Kapuskasing to Hearst, but between these two stations heavy six axle units like C630s and SD40s were explicitly banned and even modern four axle road switchers such as C424s, GP38-2s and GP40-2s are to be used “only in emergency, and at 10 miles per hour below” the regular speed limit making a GP9 pretty much the biggest unit that could be expected to run into Hearst in the 1970s and 1980s.

The north end of the ACR was also relatively light rail (but definitely better maintained than between Calstock and Nakina, which CN was trying to abandon anyway) and AC trains typically avoided using their six axle SD40 units north of Hawk Junction.

Passenger Service

Passenger service west of Hearst to Nakina (junction with CN’s main line) was actually still provided during the early 1980s by trains 272/273. While officially listed as mixed (freight and passenger) trains in the timetable, most sources seem to agree that in practice it was passenger-only in the 1980s, with any westbound freight routed via the ACR to Oba, as there was zero on-line freight traffic except for the Lecours lumber mill at Calstock, which by this point would be served by a turn job out of Hearst yard. CN was petitioning to abandon the line between Calstock and Nakina at this point, and moving the through traffic off of the line probably helped to destroy any remaining on-paper revenue and support their petition. And due to the extreme weight restrictions on the line, a lot of traffic simply could not go that way. Abandonment formally happened in 1986 and the line was torn out west of Calstock.

The (non) “mixed” typically ran with an SW1200RS and single heavyweight baggage/coach combination car. CN 7210 appears to have been the regularly assigned car on this line. This car remained in CN colours all through the early 1980s, although passenger service was officially operated by VIA Rail then. In my summer 1979 CN timetable, 273 departs Hearst at noon on Tuesdays, Thursdays and Saturdays, with 272 from Nakina running on opposite days (Wednesdays, Fridays, Sundays) and scheduled to arrive at 5:30 pm.

There was no passenger service running east out of Hearst anymore by this point in time. Hearst was once the final destination of local passenger service from Cochrane, connecting with southbound trains over the Ontario Northland to Toronto, but by the late 1970s passenger service was provided only as far as Kapuskasing by the joint CN-ONR train the “Northland” from Toronto. (Replaced later by the Toronto-Cochrane coach-only “Northlander”, which itself was discontinued in 2009.)

ACR No. 1 at Hearst, July 2, 1972. Robert Schwenk photo in my collection.

The Algoma Central’s passenger service ran daily except Monday from Sault Ste. Marie to Hearst during the spring/summer, and on the weekends only (Fridays through Sundays) during the fall/winter season. No. 1 had a scheduled arrival time of about quarter after seven during the summer, and quarter to six in the winter. The ACR train would tie down on the main track in front of the station and depart early the next morning as no. 2. (On days that the CN “mixed” ran, the inbound ACR would arrive up to two hours after, and the outbound train would be almost to Hawk Junction by the time of the 273’s noon departure.)

Freight

Local switching of the yard and local industries around Hearst would have been performed by CN, as it was their track and facilities. The lumber mill at Calstock would have also been handled by an extra turn job out of Hearst yard although I do not know when this would run.

The 1979 CN timetable shows a Kapuskasing subdivision freight departing Hearst at 11 am on Tuesdays, Thursdays and Saturdays for Cochrane. I would presume that the CN crew would spend the morning performing the local switching requirements

The corresponding westbound is not timetabled, but I would assume it to operate as an extra on opposite days (Wednesdays, Fridays, Sundays) the same as the mixed train to the west of Hearst.

My 1989 CN timetable does not have any freight schedules actually listed for the Kap. sub, and sadly I do not have one from closer to 1985.

As mentioned above, except for the lumber mill at Calstock, there was no on-line freight customers on the Pagwa subdivision towards Nakina, and due to the condition of the line, really no traffic at all was actually routed over this line anymore at this point, instead being handled by the ACR to Oba to be returned to CN for the trip westward.

The Kapuskasing subdivision and the remains of the Pagwa subdivision to Calstock (the rest abandoned in 1986) were sold to Ontario Northland in August 1993.

On the ACR side of things, ACR freight no. 5 would arrive in Hearst in the evenings on weekdays, Monday through Friday, with no. 6 departing south with interchange traffic the following day, Tuesdays through Saturdays.

Locals and turns – operations on the Northern subdivision

Posted on December 1, 2015 by Chris van der Heide

Contrasting with the south end of the railway, with heavy freight tonnage including Wawa ore and the rocky hills, steep grades, sharp curves and tall bridges that once gave the Algoma Central & Hudson Bay Railway (as it was then called) the alternate nickname “All Curves & High Bridges”, the Northern Subdivision north of Hawk Junction flattened out considerably as it moved away from Lake Superior.

Running 160 to 290 miles north of Sault Ste. Marie, this area sees the typical sort of backwoods northern Ontario railroading, serving lumber mills and logging operations, but also features the ACR’s primary interchange connections and crossings with Canadian National and Canadian Pacific’s transcontinental main lines.

No. 5 and 6

Train no. 5 was the regular northbound freight on the Northern Subdivision. Departing Hawk Junction for Hearst in late morning from Mondays through Fridays this train would handle any required switching north on the way, including the CP and CN interchanges at Franz and Oba, the lumber mills at Dubreuilville or Mead and any pulpwood spurs in between.

An ACR freight switches several empty CP flatcars from the interchange tracks at Franz after meeting northbound passenger train no. 1, July 2, 1972. R.J. Schwenk photo in my collection.

No. 5 would return to Hawk Junction the following day (i.e. Tuesdays through Saturdays) as no. 6, again performing any required switching southbound and lifting southbound traffic for Hawk Junction and Sault Ste. Marie. Freight from the arriving no. 6 would be then forwarded to Steelton yard on No. 12, departing Hawk Junction in the evenings in early 1980s timetables.

Oba Turn (No. 15/16)

On weekends, the northbound freight from Hawk Junction would just run to Oba (as no. 15 instead of no. 5) and then return the same day as no. 16). The Oba Turn would switch interchange traffic at Franz and Oba and any required overflow switching at the pulpwood spurs at Mosher.

This train no longer appears in the timetable after the shutdown of Newaygo’s operations in 1985, but presumably would have still run extra on an as-needed basis to handle steel interchange traffic from Sault Ste. Marie to Franz and Oba.

Franz Turn

In the late 1980s and 1990s, following the reintroduction of rail service at Dubreuilville, the ACR began running a weekday evening turn job out of Hawk Junction to Franz to switch the mill at Dubreuilville and interchange traffic at Franz.

Described in an older message from Reg Fitzpatrick, former station agent at Franz:

The arrangement was that No. 6 would lift first out traffic there [Dubreuilville] and the nightly Franz Turn would do the rest of the switching for the lumber ety spotting along with the chip etys which were normally stored at Wanda Mile 188 along with the regular storage track at Franz etys.

No. 5 in the AM would put these two ACIS cars into the ramp with one off spot. The loader equipment was large enough at the mill there to move one car out and pull the other one into the ramp without most times having to be done by the train crews.

And of course, as always, any overflow traffic could always be handled by the occasional extra.

Operations Today

Today of course, there are no longer any mills on the north end of the railway, however interchange at Franz, Oba and Hearst still generates a fair bit of traffic.

CN L572 rolls past Wyborn siding departing Hearst for Oba, Franz and Hawk Junction, with loads of lumber and paper from the Ontario Northland as well as returning pulpwood empties. July 2015.

The modern version of no. 5 & 6 are CN’s L571 and L572. Running daily or as required between Hawk Junction and Hearst, these handle the interchange traffic at these three locations as well as switching pulpwood cars at Langdon siding, one of the few only sources of actual on-line traffic north of Hawk Junction today. L571 and L572 are basically extensions of trains L573 and L574 between Steelton yard and Hawk Junction.
