60 technical arguments against collection of 60 arguments against Stuttgart 21 on safety and Traffic There are political and structural engineering, urban and other arguments against Stuttgart 21 If the project would bring for the rail passengers a benefit, we could talk about some of these problems. But unfortunately, this project will worsen the security of rail passengers, and also bring traffic from a technical perspective next few advantages, a number of disadvantages, as is a dismantling of the infrastructure. Here is a - certainly incomplete - collection of these safety and traffic case against Stuttgart 21 You can get the pdf files of the graphics with the author.

security -related arguments
red are marked. Among these 14 arguments, there is additional text in the security flyer in the mail on 5 February is found.
A The total area of Feuerbach Wendlingen A1 The basic idea for all connections to Stuttgart main station (Figure A1) new tunnels with a total length 55 km / 9 / to build without a geographical necessity, for the following reasons to refuse / 15 /:
A fire in a tunnel
- the temperature rises to higher levels than in fires in the open,
- the flight of people by the strong concentration of smoke greatly hindered,
- firefighters needed to rescue and fire fighting much longer than normal fires.
case of fire damage, as the 1996 and 2008 fires show in € Tunnel to expect month-long closures of the tunnel that will hamper the rail system in Southern Germany massively. But this argument is only sufficient for the setting of the project. A2 The management of long-distance traffic on the regional airport of Stuttgart or to the Regional Fair Stuttgart is unnecessary to express S-Bahn is a cost effective alternative (See Figure A2).
A3 prevent the closure of Gäubahn the S-Bahn-emergency operation of Vaihingen disturbances in the S-Bahn-Tunnel (see Figure A3)
A4 Gäubahn The closure of an emergency prevents disturbances in Filderstadt tunnel. (See Figure A4)
A5 The leadership of many of the lines to Wendlingen Filder plateau leads to unnecessary ups and downs with increased energy consumption (see picture)
A6 Bad Cannstatt is out of key regional routes ( Tübingen and direction from the direction Göppingen) not hit directly.
A7 The argument of the proponents, with Stuttgart 21 through bonds would allow for regional traffic, is false, because these are already possible with the existing station. See also C4.
A8 The distances between the rescue tunnel of the two tunnel tubes (cross passage distance) is 500 m high. The large gap makes it difficult to escape in case of fire and hampered the rescue operation in case of accidents.
examples of the cross-passage distances of other single-track tunnels:
- Perthus tunnel between France and Spain: 200 m
- Great Belt rail tunnel (Denmark, under the sea): 250 m, length 8024 m
- Guadarrama tunnel (Longest tunnel Spain): 250 m,
- Gotthard Base Tunnel (the longest tunnel in the world): 325 m,
- Euro Tunnel (Channel): 375 m.
A9 The depth of the central station is followed by uphill leading tunnels with a potential hazard associated with reduced rolling train parts (error scenario: part of the train, for example by derailment, and failure of the brakes of the downhill train part)
A10 The subway station may may not be traveled with railcars with internal combustion engine. The
not on the electrified railway line Tübingen - Sigmaringen - Aulendorf border traffic tilting trains do not work - as now - enter the station. The passengers from this region must change. Another example: Southern Railway, which consists of direct connection Friedrichshafen - Biberach - Stuttgart [11]
A11 Despite the high investment amount for the S21 to be built railway lines for freight use is not new.
B The connection of the railway station north B1 The rush to Stuttgart (from Karlsruhe, Mannheim, Heidelberg, Heilbronn, and almost all cities in the north of Main Line) is passed only through a single access track from Feuerbach. A blockade of this track will have serious impact on the railway. Today, to switch to S-Bahn tracks (see Figure 1). K21 is planning two additional tracks.
B2 as demanded by Prof. Heimerl connection between the two tunnel entrances in the north, called the P-option could mitigate the effects of the bottleneck Feuerbacher tunnel. It is not currently scheduled. That called for both by Prof. Heimerl and by Heiner Geissler (see Figure B2).
C Central Station C1 The skew risk of 15 per thousand Platform Users (rolling stroller etc.).
C2 The slope of 15 per thousand is unsafe for brake failures or mistakes of drivers and may lead to train collisions / 5 /.
C3 The inclination of 15 parts per thousand parts and makes impossible strengths of trains.
C4 The slope of 15 per thousand makes a "turning brake test" impossible, that trains can not contact / 1 /. This leads to strong restrictions of the Roadmap, as the incoming train, for example, from the north (eg from Nuremberg), exit to the north can not (for example, to Karlsruhe). Even in this situation more difficult path interference route rescheduling.
C5 The use of the station with its many stairs is difficult for disabled users, compared to a terminal station.
C6 The construction principle "platform transitions" (with a height of about 6 - 7 m) leads to unnecessarily high levels of stairs and elevators in comparison to a solution with platform-subways.
C7 connected with the high frequency of the narrow platforms leads to crowding on the platforms.
C8 The recent rescheduling of the platform steps regarding the safe distance between the rails reduced the stair width to 2.35 m [10]. Larger crowd on the stairs and above will be the result. In an emergency, eg fire, up and down fleeing people rushing rescue teams will want to use the narrow staircase at the same time, which will lead to chaos.
C9 The small number of 8 tracks, preventing change for the ITF principle.
C10 The small number of 8 tracks leading to shortages of blocked tracks, since no alternate tracks available.
C11 The small number of 8 tracks makes it difficult to create a powerful road map, refer to "mediation".
C12 The station with 8 tracks with reasonable cost is not expandable to more tracks, long-term extensions are impossible.
C13 The planned measures for fire protection are inadequate. Toxic smoke moves by the proposed flue openings from inadequate sources:. / 6 / / 12 /
C14 No stabling close to the platforms. Justification: See / 7 / page 8
C15 emergency vehicles the fire department and other emergency vehicles (ambulance, etc.) can not go directly as in above-ground station located on the platforms / 12 /.
C16 The track plan of the subway station has a serious line of conflict. At the same incoming trains to cross at the railway station in east-west direction, must either wait at the entrance or exit, until the other train left the track field. This applies to both directions (North-South and South-North) and complicates the design schedule with an argument that puts forward the DB to end stations. Source: / 13 /
D The connection of the main station south D1 ... D10 bottlenecks in the Filder, 6 bolts and 4 worm from film 11 / 2 /
D11 ... D18 bottleneck Wendlinger curve, 4 bolts and 4 worm from film 21 / 3 /
D19 Illegal safe distance (0.8 m instead of 1.2 m) for ICE trains to narrow the train tunnel on the Filder. This leads to fire for the fire to serious problems. [8] For the small tunnel diameter was granted an exemption / 14 /.
D20 Unfortunately during the height Filder tunnel. The 160 m difference in height may not be as usual with new lines, approached optimum time of swing. See / 7 /, page 12
D21 The water line in Filderstadt tunnel is usually empty. According to calculations by experts, a charge to have fire-fighting water, take 40 minutes. / 12 /
E The airport station E1 create confusion at the airport two railway stations for rail passengers because trains run on both stations.
E2 Transfer between both stations is up to the ground, long walk down and connected into the ground.
E3 The new underground station at the airport is located 26 m depth, it provides for disabled persons in case of power failure or no fire escape.
E4 The trip to the airport is increased by the long climb lasting more than six escalators and the long walk to the terminal.
E5 The existing two-track S-Bahn station at the airport is to be modified so that it comprises two single-track rail lines will contain. / 13 /
for the S-Bahn is only one track available, the other will be accessible only to local and long distance trains. (Reason for this problem are the different car floor heights of S-Bahn and Regional-/Fernbahn). The two single-track routes will lead to severe restrictions on the operating flexibility and to problems in timetabling. Example: Today may delay caused two commuter trains, for example, in two directions at the station to keep the same time. That will no longer be possible. The second train will have to wait outside the station and create further delays.
F The New Wendlingen - Ulm F1 The new line is for freight trains with a weight of more than 1000 tons impassable.
F2 The new line has a higher top than at 160 m, the existing line. This leads to unnecessary energy consumption.
F3 The new line is steeper with 35 per thousand than the existing route (Geislinger increase of 22.5 per thousand).
F4 The statement that the new line to make room for freight trains on the existing line is relative, since the existing route is unpopular in comparison to alternatives because of its steepness and unprofitable for private cars.
F5 are some single-bore double track tunnels are planned, the meetings of ICE allow freight trains is not due to the excessive aerodynamic problems. [4]
