Shotwelding - some details
- Stainless steel passenger car exteriors require very little
maintenance and no periodic painting.
- Conventional welding ruins the anti-corrosion properties of stainless
steel.
- Shotwelding was patented in the early 1930s.
- In shotwelding : two pieces of stainless steel were joined
into one uniform piece of stainless steel by attaching two electrodes
on opposite sides of the desired weld location. Then, a precisely calculated
amount of current was run for a precisely calculated instant of time between
the electrodes through the spots to be joined.
- Shotwelding produced a stronger structure than rivetting, and
made the attractive uniform silver skins of modern passenger equipment
possible.
The Pioneer Zephyr - some details
- Railroad : Chicago, Burlington and Quincy - "The Burlington
Route"
- Top speed : 110 mph
- Passenger capacity : 72
- Motive power : 600 hp diesel-electric powering two axles
- This was an "articulated" trainset which shared
wheelsets between the cars to save weight. Railways
usually overbuilt stuff and the Zephyr was unusually light and fast. The
Zephyr cars were coupled over those shared wheelsets and
the trainset could not be made longer or shorter to meet traffic demand
like other railway equipment.
- It was not designed to be compatible with the huge quantity
of traditional rolling stock available at the time.
- The locomotive engineer was in a very exposed position
if there was a level crossing collision with a truck. Fortunately there
is no record of an engineer ever complaining after such a collision.
- It probably rode like a little red wagon on a slab sidewalk,
but it was shiny and fast and captured the imagination of the Depression-era
public.
- To some extent it set the standard for the external appearance
of modern passenger equipment.
"Zephyrs" proliferate
Luxurious, standard coupling, smooth riding, electrically air-conditioned
Budd-built passenger cars were used on the train named the
California
Zephyr, operating between Chicago and Oakland (2500 miles) beginning
in 1949. Special observation "dome cars" were included in this train consist
and it travelled via several different railroads on its route. Silver
streamlined "zephyr equipment" was common and quite famous in the late
1940s, and the 1949
California Zephyr is seen by many as
the high point of the zephyr era.

River Canyon.
Notice there are 4 "Vista-Dome" cars behind the Western Pacific locomotives.
On its westbound trip, the train travelled mainly on the lines of the Burlington;
Rio Grande; and Western Pacific -
with the eastbound California Zephyr covering these roads in reverse order.
The CNR and CPR had nothing like it.
The CPR's gamble
Early in 1953, the Canadian Pacific Railway did a "me too", called
up Budd in Philadelphia and ordered 173 stainless steel cars for a new
train named "
The Canadian". (The first choice for a name
was "The Royal Canadian" but perhaps there was malice at the palace about
the idea. It would have been a violation of protocol to use such a name without
young Queen Elizabeth II's permission.) The CPR also added to their roster
of diesel locomotives to get the project rolling.
At Stoney Creek Bridge, here is a typical CPR publicity photo of
an eastbound train of the new
zephyr, I mean
Canadian
, equipment with a dome car on the tailend.
Near the headend, at the far end of the bridge, are three old sleeping
cars with ordinary painted steel sides and old-style clerestory roofs -
but they are dressed up with the special Budd stainless steel plating.
They are doing their best to adapt and be "modern".
As a "North American Zephyr", this train
was unique
in the sense that it was operated "across the continent" - Montreal to Vancouver
- by and on one single railway. The CNR operated trains on the same transcontinental
scale, but they didn't buy brand new equipment in the 1950s to create a completely
"new concept" as the CPR did.
Railway infrastructure is capital intensive - a physical
"road" must be built and carefully maintained forever.
Particularly during the two world wars, aviation technology developed
very quickly.
Canadians became proud of the bush pilots, the RCAF, and Trans-Canada
Airlines
as part of their modern national identity.
It was easy for the federal government to throw its full support behind
aviation in Canada.
It was politically attractive to support magically fast travel
on modern equipment.
In addition, those symbolic contrails in the sky from sea to sea
and far into the arctic
would be much cheaper to finance than the steel rails had ever
been.
In the 1950s, the diehard railroaders of the CPR gambled,
giving transcontinental passenger rail service
the brilliant sunset they felt it deserved.
