Steam Generators - CNR 1966


This post looks at the section of a CNR manual for its engineers on the subject of steam generators. 

New passenger rolling stock of the 1950s was still designed to be heated by steam. While it seemed clear that diesel-electric power would eclipse steam locomotives for all types of service, the railways still had a large roster of older steam-era passenger rolling stock which was still in use. For maximum flexibility, it was beneficial to ensure that trains could be made up of a mix of new and pre-diesel passenger equipment.

Furthermore, in Canada and the US, it seemed that family automobiles and air travel might soon lead to the demise of the federally-regulated, generally money-losing railway passenger business. While examples of diesel-generated electric 'hotel power' for passenger cars existed in the 1960s, railways are capital-intensive conservative organizations. No one was going to invest great amounts of money in 'new concept' equipment when the older equipment on hand would still operate acceptably well for another 30 years or so. 

... so we have this jet-age publication on keeping your passengers warm with steam.

Before you look at the 1966 document, here is a helpful overview of steam generator technology from 1950. It describes other uses of steam besides heating ... and carefully differentiates between warm climate steam generation needs, and the steam needs for equipment operating in places like Canada.

from: Locomotive Cyclopedia of American Practice; 1950-1952; Simmons-Boardman. 

Incidentally, the CNR manual below was not the last word on steam generators in Canada. 

In the late 1980s, there was a renaissance of steam generating literature publishing by VIA as it struggled to keep its 1950s-era equipment in operation. While the equipment was designed to require 'a minimum of attention' on the road (in the 1950s), VIA sometimes hired 'train riders' to operate and troubleshoot their old steam generator equipment on its transcontinental trains as it became less and less reliable.









Page SG 8 should be on the reverse of  Page SG 7 (above) but the page is blank.
Unfortunately, that page includes procedures for starting when the ambient temperature is below freezing.
... something we'd all be interested in learning about in Canada.

I'll take this printing error up with the CNR's mechanical department!

... Don't worry - I've got lots of steam generator information to share in future posts.

In lieu of page SG 8, please accept this 1982 photo of a westbound
made up of original CNR equipment, steaming away at Kingston station.



So, I guess we must pick up the procedures when it's time to shut down the steam generator ...

1967 Confederation Train - Documents and Steam Generators


This post continues to examine Confederation Train sheets and logs purchased years ago at a railway show. The Confederation Train was a modern museum on wheels which travelled across Canada during Canada's Centennial of Confederation, 1967. 

A third and final post will include the most interesting materials from this series.

The first pages reproduced below come from an annual handbook put out by the Government. The publication was produced for at least four decades and was written for a general audience. It covered all aspects of Canada: its citizens, industry, natural features, culture, etc. 

... The editions issued in certain years provided greater emphasis on different subjects and prominent projects, for example: 1940s, Trans-Canada Air Lines (originally part of the CNR); late 1950s, nuclear technology development, and Canada's sharing of this knowledge with other countries for nuclear medicine and power generation.

The 1967 edition of the handbook was at least double the usual thickness as Canadian history and progress over a century were being described. 

In 1967, over half of all Canadians were under 25 years of age. Many Canadian adults had been shaken up by World War Two and many people were still alive who had experienced the Great War. In the late 1950s arrived a new menace - the threat of nuclear war wiping out all of civilization's progress on the planet.

However, for one reason or another, in 1967, most Canadians realized they were very fortunate indeed. As you will infer, a great deal of hope was invested in the potential of the youth of Canada. 

From the Federal Government's perspective, the pages below describe how we will celebrate in 1967. You'll notice that the Confederation Train (and the truck caravans) represented a large proportion of the national program of celebration.

Here is another tranche of the Confederation Train motive power documents.
Below, my practice of moving from less interesting to more interesting items continues.

Steam Generators

In many cases, looking for 'history' on the internet is an exercise in nostalgia. Internauts seek out information and artifacts which remind them of experiences, now lost in the past, which they remember with fondness. For those people, it is the papers reproduced here which may be of greatest interest. 

People like Rolly Martin (whom I met exactly 40 years ago, as I write this) could explain and discuss these technologies, and their experiences with them, for hours. 

For example, in the last years of the operation of The Canadian along Lake Superior, during cold weather, VIA would supply train riders whose job it was to 'keep steam up' in circa 1955 diesel-electric locomotives so train heat could be maintained and the passengers kept comfortable. 

One night, Rolly and his mate got a call from their conductor requesting more heat. As I have written before, Rolly left the 6400-class engine, went back to the 30-year-old trailing unit ... and the VIA train rider witnessed a former CPR steam locomotive fireman getting a steam generator plenty hot ... there were no more requests made for more heat for the balance of the trip. Every time Rolly told me that story over the years, I sensed that he had derived a lot of satisfaction from that single event.


For everybody else ...

... That is, for people too young to have be running VIA trains in the 1980s, or for general-interest readers of the future, there may be an interest in understanding WHY steam generators existed in the first place.

Back around the time of Canadian Confederation, passenger cars were made of wood. In winter, they were heated by stoves burning wood, and later coal or coke. In a simple derailment or in a collision, the wooden cars would suffer damage and/or upset - often trapping some passengers inside. Frequently, the stove would fall over during the accident, setting the wreckage on fire, and the trapped passengers would be killed in the resulting blaze.

In the decades which followed, steam locomotive technology developed and they began burning coal instead of wood. Because of public outrage - stirred up by newspapers - and government regulatory action ... a way to safely pipe steam back through passenger cars, to operate steam radiators, was developed and applied to passenger trains.

Larger, more powerful locomotives, which could generate surplus steam through the use of more energy-dense coal, AND the development of train steam systems to heat (and eventually, cool) cars made it possible to eliminate fuel burning stoves on passenger cars. As well, newer passenger cars - built primarily out of steel - protected passengers more effectively. 

In the 1920s, Canada and the US had a good supply of these modern steam-heated cars and they continued to be built well into the 1950s. These cars might have useful lives of 30 to 50 years. 

However, in the late 1940s, many railways got into a money-saving headlong rush to replace labour-intensive energy-hog steam engines with diesel-electrics. The diesels had no need to make steam for propulsion. 

The existing passenger car steam heat systems were efficient enough that it didn't make economic sense to scrap this equipment. To facilitate diesel locomotive sales, the builders ensured that many new diesels could be equipped with 'steam generators' inside for passenger train service. 

The CNR, with greater car heating needs than many southern US railways, refined steam heating technology a little more ... by developing separate cars designed solely for the purpose of generating steam.

The Confederation Train had both a CNR steam generator car and locomotives with on-board steam generators.

Steam Generator Operating Details


For both the people who knew them, and for people interested in understanding steam generators better, I have included the most helpful diagrams and descriptions I could find from a particular manual. I think this is probably representative of the equipment to be found on the Confederation Train.

When viewing the ornate colour diagram of the generator's various systems, be sure to slide all the way over to the right to see all of it.

Forty years later, there was a renaissance, of sorts, in the publishing of steam generator documentation. VIA produced some plasticized fan-fold pamphlets for quick reference by train crew members who hadn't apprenticed as CPR locomotive firemen.

Rhetorically, if these complex machines were kept operating in VIA's CNR and CPR heritage equipment for about 40 years ... is it any wonder that imperfect maintenance and operating technique ... and just plain wear and tear ... made VIA's winter trains subject to uncomfortable temperature fluctuations before the completion of HEP conversion (electric heat)?

VIA 1981 to 1985, Kingston in the Winter




This post looks at VIA trains at Kingston in the early 1980s.
It is a thematic exposition combining leaking high-pressure steam with snow.



The Era:

In the early 1980s, bulbs with incandescent tungsten filaments lit our homes 
and saturated hand-held time exposures with yellow.

In high school, kids had the option of taking instrumental music classes.
There is enough knowledge and talent here to synthesize Christmas carols or locomotive whistles.



Nearby: An eastbound rolls by mile 183 on the Kingston Sub.
The rail snapshots before the timetable are circa 1981 and were taken with a camera using 110 cassette film.



A common sight - VIA 6523.



The westbound is loading one of the last cars ...



... the long train has the power and the leading steam leak spotted beyond the end of the platform.
Pardon my corona.

The ties piled so nicely may have come from renewals between the platforms.

The next time your new LRC is stalled somewhere in the bush, don't despair and pass out ...
you might see a chickadee or something on a fencepost while you wait.

As I take another careful over-the-shoulder potshot at interpreting recent Canadian railway history,
I can assure you that I have not included photos of trains 561, 565, 560 or 564.

We made rather merry at the sight of such VIA-decorated rolling stock at the station.
The evolving Napanee/Brockville-Smiths Falls-Ottawa track network was not being kind to VIA.


A lifelong contempt for fine print reference marks has caused me to enlarge them significantly.





I don't know if that is an Engine Service Brakeman, Baggageman or a train-rider Steam Technician talking into the cab.



The snow hi-lites the small total area where rail adhesion occurs.
... Unlike trains 561, 565, 560 and 564.





From CN comes a steam-lined RS-18 with no steam generator of its own.



Notice the low-mileage Sears garden tractor used in baggage service on the north platform only.

Princess Street once included a double-tracked section of the
Kingston Portsmouth & Cataraqui Electric Railway.

Among other places, it provided service to
the penitentiaries, the asylum and the Grand Trunk 'outer station'.
