Dressing for Speed

In May 1936 a crossing gate guard on the important Berlin � Hamburg line
was alerted by an almost unearthly but rapidly approaching howling. He likened
it to a steam-powered siren. Before he could collect his thoughts, his humble
crossing was host to the thunder and enormous speed of the streamlined
locomotive 05 002 pulling four express coaches. With observers from the
Reichsbahn on board, the thundering burgundy-colored machine recorded a speed of
200.4 km/h (124.52 mph). Paul Roth, from the Reichsbahn�s Berlin-Grunewald
test facility, who was on board during the test run, likened the unearthly howl
emanating from the smokestack of the BR 05 to its boiler working probably
dangerously close to the edge of the envelope, as we like to say in today�s
techno jargon.
Some time after Errol Kubicki and I had completed our article on tenders, I
asked him if he had any ideas for other articles. After several e-mail
exchanges, he asked what I knew about streamlined Dampfloks, specifically
streamlined tank engines. Well, I never really paid much attention to them �
tank or otherwise but that I�d be willing to do a little investigating. To
urge me on, Errol lent me a copy of
Modell Eisen Bahner featuring a
fairly detailed article on the topic. So, here goes.
Much as we admire the sight of a steam locomotive with its jungle of pipes,
valves, connecting rods, and much more of the external necessities that propel
the machine, this beloved mechanical jungle does little to improve the
efficiency of what is already a rather inefficient machine. By the 1930s, the
major locomotive builders in Europe, specifically Germany, realized that, if
they were to compete with lighter, more aerodynamic railcars such as "Der
Fliegende Hamburg" and the up and coming electric locomotives like the E
18, they would have to take a closer look at clothing their Dampfloks in an
aerodynamic shell.
While this well-known run set a record, Wolfgang Messerschmidt, the famous
German railroad historian, thinks it is (was) not a record. Being quite familiar
with American steam locomotive technology, he feels that some streamlined Alco
steam locomotives achieved speeds as high as 230 km/h (142.9 mph). This, of
course, also eclipses the run made by "Mallard" in England at 202.7
km/h (125.9 mph) but this latter figure is disputed since it was allegedly done
on a slight down grade. Actually, some minor attempts to impart some
windcheating form to locomotives go back to the early part of the 20
th
century when cabs began to be enclosed and the front of the boiler was
fabricated in a more conical shape. Take a look at the Bavarian S 3/6
locomotives.
The Beginning
Still, in Germany the effort to develop a more efficient streamlined steam
locomotive was on and became more earnest in 1932. William Beil, the director of
engineering at Borsig in Berlin (Hennigsdorf), recalls that they were looking at
speeds in the 150 km/h (93 mph) range since that was already possible with
lighter self-propelled railcars. Borsig conducted some windtunnel testing at its
own expense and the Reichsbahn did similar work at the University of G�ttingen.
The result was that Lok 03 154 was fitted with a more aerodynamic cab and a
parabola shaped boiler door. The running gear and boiler were also enclosed with
the enclosures featuring suitable access panels for maintenance. Steaming at 150
km/h (93 mph) it quickly became evident that the engine was able to pull more
cars with less effort. This was attributed not only to the streamlining but also
to the increased thermodynamic efficiency realized by the streamlining. At the
time, William Beil calculated that the streamlining contributed an extra 290 hp
at 120 km/h (75 mph). Further calculations for speeds of 160 km/h (100 mph)
showed that additional tractive effort would result which would translate
directly into hauling more passenger cars.
All of this success led directly to incorporating this technology into the BR
05. As this new project began to, pardon the pun, take shape, the DRG also asked
Borsig to streamline
03 193. By then the DRG had also mandated that passenger locomotives capable
of speeds exceeding 140 km/h (87 mph) would be equipped with streamlining.
Affected were BR 01
10, 03
10, 05 and 06. While this speed
demarcation was in effect at the Reichsbahn, this concept was basically ignored
in other countries. In the mid-1930s it had become fashionable, especially in
the United States, to streamline locomotives whether or not any performance
benefit would be realized or not. Fashionable or not, the German locomotive
builders also had to be increasingly concerned with the competition offered by
the already mentioned lighter and more aerodynamic railcars and electric
locomotives. Not only were these quite efficient but they were also very
attractive from a marketing viewpoint.
The ubiquitous BR 01 and BR 03
At first sight the famous BR 01
10 and BR 03
10 look
almost identical but the difference was more skin deep with the BR 01 being the
heavier duty machine with greater axle loading. The lighter duty BR 03 and its
BR 01 counterpart were both destined to be clothed with streamlining.
Altogether, these types were the most widely built and used streamliners.
Initially, the DRG wanted to order 205 of the BR 01
10 but the war
reduced this by nearly 75 percent. Most survived those years and in 1949 they
were overhauled but their streamlining was removed. Similarly, the original
order for 140 of the BR 03
10 streamliners was reduced to 60 at the
start of the war. After the conflict, the DB and DR overhauled them but also had
their streamlining removed.
The BR 05 in two versions
"In the BR 05 German steam engine development had reached its highest
point." Those were the words of the editors of "
M+F Journal"
25 years ago. That this is unarguable was proven in May 1936 when 05 002 broke
the 200 km/h (124 mph) barrier. Three streamlined BR 05s were built by Borsig
under the direction of Richard Paul Wagner at the DRG - two conventional (05 001
and 05 002) and one cab forward (05 003). All were 2�C2� (4-6-4)
three-cylinder machines with five axle tenders.
(Author�s note: This is the
Wagner whose name is applied to the large smoke deflectors)
The conventional BR 05s were delivered in March and May 1935. Both entered
revenue service in 1936 on the Berlin � Hamburg line. During the May 1936
record run, 05 002 developed over 3,400 hp (2,535 kW). With advent of the war,
both were sidelined since high speed passenger service was deemed superfluous.
They survived the war and in 1950, Krauss-Maffei dismantled the streamlining and
reduced the boiler pressure to 16 bar. They then entered regular service in 1951
and were retired in July 1958. Engine 05 001 was installed in the N�rnberg
Transportation Museum complete with its original streamlining. Together with 05
001, the two Loks regularly reached speeds of 150 km/h (93 mph) and 175 km/h
(108 mph) on some stretches.
The cab forward design was radical by any measure. The engine was delivered
in the fall of 1937. Unlike the Southern Pacific cab forward engines, the design
of the 05 003 was intended primarily to provide better visibility for the crew
at the anticipated high speeds. The obvious impossibility of trying to shovel
coal into the boiler resulted in use of a stoker system that moved coal dust
through a 14 m (46-ft) long pipeline. Even the use of coal dust proved
difficult. Test results with two types of coal (brown and hard) were less than
satisfactory. In 1944, 05 003 was rebuilt into a conventional locomotive but
without streamlining. Its livery was wartime camouflage paint complete with
strategically located armor plate to protect vital parts. After surviving the
war, Krauss-Maffei overhauled this engine in 1950 and it joined the other 05s in
revenue service. The ideal fuel would have been oil but this was not considered
since it would have meant use of a very strategic material. Besides, the DRG had
only very limited experience with oil-firing.
The Mammoth BR 06
The BR 06 was developed in 1933. It was necessary to have a high-performance
locomotive for more mountainous areas and the all-important Berlin �
Frankfurt/Main and Berlin � Munich lines. The new prototype engine had to be
able to pull 650 ton trains at 120 km/h (75 mph) and on more severe grades at 60
km/h (37 mph). But, it was not until April 1939 that Krupp delivered the
prototype three-cylinder BR 06 (06 001), a 2�D2� (4-8-4) design. It and its
mate 06 002 were then the largest steam locomotives built in Germany. Their
impressive size was further enhanced by their huge partially exposed drivers.
Alas, the machines disappointed. There were boiler problems but perhaps
potentially more serious was their inability to negotiate radii of 140 m (460
feet) without the possibility of derailing. Some railroaders also cast doubt on
the machines� inability to safely negotiate some of the very complex turnout
systems in place at that time. One of the driven axles was even flangeless.
These limitations and the advent of more efficient electric locomotives on the
Berlin � Frankfurt and Berlin � Munich lines doomed the BR 06. It never
entered series production. Engine 06 001 was taken out of service in 1951 and 06
002 was hit by a bomb and destroyed during the war.
BR 61 and Henschel - Wegmann
Enter the locomotive builder Henschel & Sohn and the car builder Wegmann
& Co. This team designed and developed a streamlined locomotive and suitable
passenger cars to compete with the railcars. It was to be a relatively light
train based on a 2�B1� (4-4-2) tank engine and passenger cars featuring
Jacobs trucks. The DRG, however, wanted the design to make greater use of
existing standard designs for both the locomotive and cars. What emerged was a
streamlined BR 61 (61 001) and matching passenger cars painted in attractive
aluminum and violet colors.
The train made its debut in May 1935 on the Berlin � Dresden route. In
acceleration and top speed it matched "Der Fliegende Hamburg." Top
speed was 185 km/h (115 mph), but at 150 km/h (93 mph), the locomotive�s running characteristics were not nearly
as stable as those of other streamliners, notably the BR 05. Nevertheless, the
new train did the 176 km (109 mile) Berlin to Dresden route in 100 minutes, a
speed of 64 mph (103.5 km/h). The limited water capacity of the BR 61 was also
an issue. Still, the train entered service. At war�s end, it was stationed in
Braunschweig. It was then outfitted for service between Hannover and Bielefeld.
An accident in 1952 led to its retirement.
To overcome these objections, in 1939 Henschel delivered a larger
three-cylinder BR 61 (61 002) with the unusual axle configuration of 2�C3�
(4-6-6). To accommodate the increased coal and water capacity, Henschel chose
the three-axle trailing truck and too keep axle loading at the 18.5 tons
dictated by the Reichsbahn. The new machine performed very well but scheduled
service between Berlin and Dresden did not materialize and by 1943 both 61 001
and 61 002 gave up their attractive paint scheme and reverted to dreary wartime
gray. But, the story of 61 002 did not end here, and as the immortal Monty
Python gang often said, "and, now for something completely different."
After World War 2, 61 002 remained in the Soviet occupied zone of Germany.
The servicing facility in Dresden had little use for the one-off locomotive
other than to use it for various general purpose tasks. For a while, the engine
was used for the personal train of the transportation minister but even while
serving this dutiful bureaucrat, the machine exhibited all sorts of ills. As it
turned out, the railway development center in Halle needed locomotives capable
of at least 160 km/h (100 mph) to test high speed passenger cars then under
development. The overhaul facility in Meiningen was given the job to convert 61
002 to a conventional tender locomotive of 2�C1� (4-6-2) configuration
capable of 180 km/h (112 mph). The tender was from a BR 44 (44 468). The outside
cylinders were from H 45 024, an experimental coal dust fired Lok with a
condensing tender. (The less than elegant H 45 024, in turn, was derived from a
conventional BR 45.) The reborn engine, now oil-fired, was designated 18 201 and
in honor of the first German Pacific, a Badische IVf in 1907. This Lok used the
18 201 number in 1925. To some extent the new, green 18 201 looked like the
Bundesbahn�s BR 10 of 1956.
The little BR 60
Though not intended to break or even approach high speeds, the private
L�beck � B�chener Eisenbahn (LBE) ordered two streamlined BR 60s from
Henschel. The two modest two-cylinder locomotives (60 001 and 60 002) were
delivered in 1936. The LBE combined these with two-level coaches. The two trains
were used in pull-push service on the Hamburg � L�beck � Travem�nde line.
The little tank engines were capable of 120 km/h (75 mph). The LBE ordered a
third slightly more powerful BR 60 streamliner (60 003) in 1937.
With the start of the war, the DRG de-emphasized high speed passenger traffic
and relegated the BR 60s to heater service but eventually only 60 001 was used
for that. In 1945, 60 002 and 60 003 went to the East German DR. Engine 60 002
was in service in the Berlin suburbs until 1958 and the third machine served
until 1962 near Stralsund.
The Unconventional BR 19
Yet another but the last attempt to build another aerodynamic steam engine
was Henschel�s design for the BR 19. In its outward appearance, the 19 1001
was very similar to the BR 01 and BR 03 streamliners. It was a decidedly
unconventional machine of 1�Do1� (2-8-2) configuration. Four two-cylinder
steam engines were used. On the right side, two engines powered the first and
third driven axle and on the left side a similar arrangement powered the second
and fourth driven axles. It was delivered to the DRG on June 13, 1941 and after
solving some teething problems, the BR 19 showed stable and quiet running
characteristics. Trials on a dynamometer at the DRG�s Grunewald (Berlin) test
facility showed that speeds of up to 200 km/h (124 mph) should be easily
possible. A promising start, indeed.
In tests on the Berlin � Hamburg line the machine reached 186 km/h (115
mph), a speed that was not only attributed to its unconventional propulsion
system but also to the well designed streamlining. While the potential was
clearly there, the times did not permit further development. In May 1943, the
engine was transferred to Bw Altona (near Hamburg) and used in revenue service.
A bomb hit in early in 1944 damaged 19 1001 but she was repaired only to be hit
again in August 1944, but this time more severely that was followed by
sidelining. In April 1945, the unusual machine was discovered by the advancing
American troops, taken into custody and then shipped to Fort Monroe in Virginia
in October of that year. Industry engineers and others examined the Lok but did
not run it. As a matter of fact, the machine never ran again under its own
power. The advent of dieselization by the American railroads quickly obsoleted
steam power. By 1952, the engine was scrapped.
The BR 10
No doubt the last gasp in search of a more streamlined steam engine was the
BR 10. It was a very advanced three-cylinder 2�C1� (4-6-2) and, according to
Wolfgang Messerschmidt, it was really a pseudo-streamliner. Krupp built the only
two of these prototypes in 1956, which were intended to replace the BR 01
10
and BR 03
10. The first, 10 001, was coal-fired and its mate, 10 002,
was oil fired. The machine�s axle loading of 22 tons imposed restrictions on
many lines and, in addition, not all lines permitted its service speed of 140
km/h (87 mph). With times and technology changing rapidly, the end of steam was
clearly in sight. Both were retired in 1967.
The End of an Era
As we saw, those streamliners that survived the war were stripped of their
elegant windcheating exteriors. Soon the groundbreaking V200 came on the scene
as did the E18 before the war. Both were clearly more efficient and faster but
even they are retired now. Today�s passengers on the ICE will probably never
have heard of the mighty 05 002�s record run. The longest lived streamliner
was no doubt 01 1102 delivered in the summer of 1940 and served until 1974. It
is now restored and still operating much to the delight of Europe�s steam
enthusiasts.
