DETROIT'S DOUBLE-DECKER BUSES
Between November 1926 and early 1927 a fleet of fifty (50) gas-electric double-decker buses, built by the American Car
& Foundry Company (ACF), were delivered to the DSR. These sixty-passenger buses were placed into service on heavy
lines such as John R. and Chalmers. An unfortunate mishap would remove their upper decks by 1930.

No doubt most, if not all, have at one time or another viewed photos of London, England, or other cities across the United
Kingdom, and couldn't help but notice all those double-decker buses darting along their roads and highways.  But perhaps
the most familiar model double-decker bus of recent time are the famous red-colored
London  Routemaster buses.  The
Routemasters
were very popular with Londoners and tourists alike, and have become one of the famous icons of London.
Sadly though, the last of the London Routemaster buses were retired from regular service in December of 2005, and were
replaced by -- you guessed it -- a new fleet of red double-decker buses!

Although still quite popular in a number of cities across Great Britain, Ireland, Germany, and even in Hong Kong, the use of
double-deckers here in North America has been quite limited.  However, many might be surprised to learn that at one time
double-decker buses actually operated along the streets of Detroit.
In 1920, the Detroit Motorbus Co. became the first local bus company to operate double-deck buses
along the streets of Detroit.  DMB operated various makes of these double-decker buses on streets
such as East Jefferson, Cass, John R., Second Blvd. and Dexter.

The first double-decker
buses to operate along
Detroit  streets  were
operated by the former
Detroit Motorbus Co.
the privately-owned  
bus  company  which
operated within the city
from 1920 thru 1932.
The double-deckers first
began operating on the
company's flagship line,

E. Jefferson
, but soon
saw service on many of
their other lines as
DMB
routes expanded out to
farther parts of the city.
The  company's   
Cass
Avenue-Second Blvd,
This ACF built DSR double-decker (#547) was
suppose to be heading to the Ford Highland Park
plant on Woodward and Manchester, while working
the heavy John R. line. Unfortunately, it seems to
have encountered a slight problem in the vicinity of
Eight Mile and Oakland, by winding up in a ditch
along Eight Mile Road.

Since the  Detroit Motorbus double-deckers proved to be popular
with Detroiters, the city-owned  
DSR decided to buy a fleet of its
own  double-decker buses. However, the first  double-deckers for
the
DSR were actually 'leased' from the DUR's  People's  Motor
Coach Co.
 Beginning in July 1926, seven of the DUR's two-man
open-top
Yellow Coach double-deckers were leased by the DSR
for peak-hour use on the
DSR's busy John R. and Conant lines.

That same year, a fifty coach  
DSR  order went to a local  builder,
the  
American Car & Foundry Company,  and the buses were
built at the company's Detroit railway car plant, located on Russell
and Ferry streets. The enclosed upper deck
ACF coaches, model
519-4-F1, were sixty-passenger gas-electric double-deckers, and
were numbered  
#501-550.  These were the first buses built by
American Car & Foundry, and the only double-decker coaches
ever built by that company.

The fleet began arriving in November 1926, and were assigned to
a number of the department's more heavy lines. Seventeen were
assigned to the Second Avenue Garage for service on the heavy

John R.
line  (which serviced the Ford Highland Park auto plant),
and the
Conant line.  The remainder of the DSR double-deckers
were  assigned to  the Kercheval Garage  for service on  both the
Cadillac and Jefferson Express  routes, and the Chalmers line.
The
DSR operated these coaches using a one-man operation.

However, a mishap occurred during  the summer of 1927  which
would change the future of double-decker bus service in Detroit.
It seems that the driver of one of the
ACF coaches tried to enter
Belle Isle through the Jefferson Avenue underpass on East Grand
Blvd., after forgetting that he was driving a double-decker coach.

coaches
(see top photo)  that were reduced to a single-decker. Between 1929 and 1930 the DSR's
entire fleet of double-decker coaches had their upper-decks removed.

John R. St.-Grand Blvd, and the heavy Dexter Blvd-Cass lines were all assigned double-decker buses.   

The first fleet of
DMB double-decker coaches were built by the Fifth Avenue Coach Company, and originally came with
open-top upper decks. Eventually, they were later semi-enclosed with new tops, with a canvas covering added during the
winter. Additional fleets of double-deckers were later purchased from
Yellow Coach and the Six-Wheel Company.
Needless to say, the coach suffered upper deck damage and was soon reduced to a single-decker.

This redesigned coach would evidently serve as the model for the others.  Due to poor design and construction, the
ACF
fleet began to encounter problems, ranging from cracked upper deck windows to broken body posts.  Consequently, the
DSR had to invest $12,050 to redesign the remainder of the fleet. Between February 18, 1929 and October 1, 1930, the
upper decks were removed from the entire
ACF fleet, resulting in 31-passenger single-deck coaches.  The last of the ACF
converted single-decker buses would continue on in service until 1937.
