TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a rail vehicle provided with a blast-resistant partition
wall.
BACKGROUND ART
[0002] A rail vehicle comprising a car body structure, a driver's cabin, a passenger compartment,
and driver's cabin back wall partition separating the driver's cabin from the passenger
compartment is disclosed in
DE 198 38 236.
[0003] Rail vehicles provided with a driver's cabin and a passenger compartment usually
include a partition between the driver's cabin and the passenger compartment, which
provides a secure fire barrier, and includes a door for access to the passenger compartment
from the driver's cabin and vice-versa, and a means of egress from the driver's cabin
in an emergency.
[0004] Additional requirements have emerged to take into account terrorist attacks, which
are not fulfilled by the conventional designs. It is of particular importance to counteract
attempts to disable the driver, whose actions during a terrorist attack are essential
to limit the extent of the attack, safeguard the passengers and initiate the rescue
operations.
SUMMARY OF THE INVENTION
[0006] The invention aims to provide an improved design for a rail vehicle comprising a
driver's cabin and a passenger compartment, which will prevent assailants from disabling
the driver.
[0007] According to the invention, there is provided a rail vehicle comprising a car body
structure, a driver's cabin, a passenger compartment, and driver's cabin back wall
partition separating the driver's cabin from the passenger compartment, wherein the
driver's cabin back wall partition comprises partition panels made from a blast-resistant,
missile-resistant and fire-resistant composite material.
[0008] The driver's cabin back wall partition further comprises a framework comprising a
floor section, two body side vertical sections and a roof section, directly fastened
to the car body structure, and the partition panels are directly secured to the framework.
The framework provides a robust structure that will transfer blast pressure loads
on the partition panels to the car body structure.
[0009] According to a preferred embodiment, the composite material of the partition panels
comprises a sandwich assembly, preferably an autoclaved sandwich assembly, comprising
a core material between a stainless steel plate on a passenger compartment side and
a driver's cabin side plate made of stainless steel, fibreglass plate or carbon fibre
on a driver's cabin side. The core material of the composite material of the partition
panels may comprise vermiculite. The driver's cabin side plate may comprise S2-glass
fibres. The vermiculite core provides the fire barrier, the S2 glass provides the
penetration resistance and the strength afforded by the autoclaved sandwich construction
provides inherent blast resistance.
[0010] Preferably, the driver's cabin back wall partition further comprises one or more
trim panels covering the partition panels and facing the passenger compartment, the
trim panels being preferably made of aluminium. The trim panels, apart from their
aesthetic function, contribute to the overall penetration resistance.
[0011] According to a preferred embodiment, the framework further comprises a doorway frame
directly secured to the roof section of the framework at a top end and to the floor
section of the framework and/or to the car body structure at a lower end, the driver's
cabin back wall partition further comprising an access door fitted into the doorway
frame. The doorway frame comprises at least two vertical edges. It is preferably a
U-shaped or rectangular structure with a top edge and/or a bottom edge joining the
two vertical edges. Preferably, the access door comprises a door panel manufactured
from a blast-resistant, missile-resistant, fire-resistant composite material. The
composite material of the door panel may comprise a sandwich assembly, preferably
autoclaved, comprising a core material between a stainless steel plate on a passenger
compartment side and a driver's cabin side plate made of stainless steel, fibreglass
or carbon fibres on a driver's cabin side. The core material of the composite material
of the door panel may comprise vermiculite. The driver's cabin side plate of the composite
material of the door panel may comprise S2-glass fibres.
[0012] Preferably, the access door is hinged to the doorway frame so as to open into the
passenger compartment only. In a closed position, the access door bears against the
doorway frame along at least along two and preferably at least three edges of the
access door. This further contributes to the overall blast resistance of the driver's
cabin back wall partition.
[0013] According to one embodiment, the doorway frame is equidistant or substantially equidistant
from the body side sections of the framework.
[0014] Advantageously, the door and doorway frame are provided with a key-operated lock
with at least three, preferably at least four latches. The latches can be located
along the vertical edge of the door opposite the hinge and/or along the horizontal
upper edge of the door.
[0015] To further prevent the blast pressure pulse entering the cab, the rail vehicle may
further comprise a driver's cabin HVAC system connecting the driver's cabin to the
outside of the rail vehicle without entering the passenger compartment.
[0016] According to one embodiment, at least one back wall cubicle is located in the driver's
cabin directly adjacent to the driver's cabin back wall partition. The back wall cubicle
may have a back wall cubicle framework directly secured to the car body structure.
Such cubicles provide additional structural support after the partition and door have
deflected under blast load by a few millimetres.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0018] With reference to figure
1, a rail vehicle
10 comprises a car body
12 divided into a driver's cab
14 and one or more passenger compartments
16 by a driver's cabin back wall partition
18.
[0019] As illustrated in figures
2 and
3, the car body
12 has a car body structure
20, which comprises a floor section
22, two body side sections
24 and a roof section
26, and consists of structural members such as longitudinal lower girders
28 and floor planks
30 in a floor section
22, external side wall planks
32 and upper cant rails
34 in the two body side sections
24 and roof planks
36, 38 joined to the external side wall panels
34 by the cant rails
32 in the roof section
26. The roof section
26 is raised in the driver's cabin
14 compared to the passenger compartment
16, and comprises a vertical diaphragm
40 joining the somewhat higher roof planks
36 of the driver's cabin
14 to the lower roof planks
38 of the passenger compartment
16. The structural members
28, 30, 32, 34, 36, 38, 40 are preferably made of aluminium and are permanently fastened together by any appropriate
means, e.g. by welding or with rivets.
[0020] The driver's cabin back wall partition
18 is illustrated in more details in figures
4 and
5 and comprises a framework
42, which is directly secured to the car body structure
20, e.g. with rivets or preferably with removable fasteners such as M
8 bolts. The framework
42 comprises of a floor section
44, two body side vertical sections
46 and a roof section
48. The floor section
44 consists of left and right hand floor channels
50 manufactured from aluminium extrusions, which follow the profile of the floor planks
30 and are fastened directly to the floor planks
30. The two body side vertical sections
46 consist of left and right hand body side channels
52 manufactured from aluminium extrusions, which follow the profile of the external
side wall planks
32 and are fastened directly to the external side wall planks
32. The roof section
48 comprises a two-piece diaphragm top beam
54 made from aluminium extrusions, which extends from one upper cant rail
34 to the other and is secured directly to the upper cant rails
34 and to the diaphragm
40.
[0021] The framework
42 further comprises a one-piece doorway frame
56, which is an aluminium construction comprising at least two parallel vertical edges
58 joint at the top by a horizontal top edge
60 and at the bottom by a horizontal bottom edge
62. The top edge
60 is directly fastened to the diaphragm top beam
54 while the bottom edge
62 is directly secured to one of the floor planks
30.
[0022] Left and right partition panels
64 close the driver's cabin back wall partition
18 on each side of the doorway. The partition panels
64 slide and locate into the channel sections of the body side channels
52 and floor channels
50 of the framework and are further supported by the diaphragm top beam
54 and by the vertical edges
58 of the doorway frame
56.
[0023] The partition panels
64 are made from a blast-resistant, missile-resistant and fire-resistant composite material
66, illustrated in figure
6 and directly secured to the framework
42. The composite material
66 of the partition panels
64 is an autoclaved sandwich construction comprising a 20 mm vermiculite core
68, with 0.8mm stainless steel plate
70 on the saloon side and 3 mm of S2 glass
72 on the driver's cabin side. The vermiculite core
68 provides a fire barrier, the S2 glass provides penetration resistance and the strength
afforded by the autoclaved sandwich construction provides inherent blast resistance.
[0024] As illustrated in figure
5, the partition panels
64 can be covered by 3 mm aluminium trim panels
74 facing the passenger compartment
16. On the passenger compartment side, an emergency ladder stowage compartment
76 can be provided. These elements, however, only slightly improve the penetration resistance.
[0025] The driver's cabin back wall partition
18 further comprises an access door
78 fitted into the doorway frame
56. The access door
78 comprises a door panel
80 manufactured from a blast-resistant, missile-resistant, fire-resistant composite
material
82. The composite material
82 of the door panel is very similar to the composite material
66 of the partition panels
64 and consists of an autoclaved sandwich construction comprising a 20 mm vermiculite
core
84, with a 0.8mm stainless steel plate
86 on the passenger compartment side and
5 mm of S
2 glass
88 on the driver's cabin side (see figure
7). In order to provide the necessary penetration protection, the door panel
80 requires 2 mm more S2 glass material than the partition panels
64, because the access door
78 does not benefit from an aluminium trim panel.
[0026] The access door
78 may comprise a metallic rectangular door frame and is hinged to one of the vertical
edges
58 of the doorway frame
56 so as to open into the passenger compartment
16 only. In the closed position, the access door
78 bears against the doorway frame
56 at least along the vertical edges
58 and the top edge
60 of the doorway frame
56. As an option, the bottom edge
62 may be provided with a step on which the bottom edge of the access door
78 bears in the closed position to provide further structural support. However, consideration
should be given to potential tripping hazard issues for train personal going through
the doorway.
[0027] The access door
78 and doorway frame
56 are provided with a key-operated lock with at least three, preferably at least four
latches.
[0028] One or more back wall cubicles
80 are located in the driver's cabin
14 directly adjacent to the back wall partition
16. Each back wall cubicle
80 has a back wall cubicle framework
82 directly secured to the car body structure
20.
[0029] The rail vehicle comprises a driver's cabin HVAC system with and HVAC ducting
84 that connects the driver's cabin to the outside of the rail vehicle without entering
the passenger compartment
16.
[0030] The overall design of the driver's cabin back wall partition
18 provides a secure barrier against penetration due to explosion or terrorist act in
the adjoining passenger compartment
16, which might disable the driver, and more specifically against penetration due to
blast pressures and missiles (bullets).
[0031] In a blast situation, the blast pressure loads will be reacted by the compression
of the partition panels
64 and access door panel
80 onto the driver's cabin back wall partition framework
42 and into the car body structure
20. Additional support is provided by the back wall cubicles
82 after the partition and door panels have deflected under blast load by a few millimetres.
[0032] The relocation of the driver's cabin ducting
84 completely outside the passenger compartment
16 further prevents the blast pressure pulse from entering the driver's cabin
14.
[0033] The autoclaved sandwich materials
66, 82 selected for the partition and door panels
64, 80 provide a good missile penetration resistance without compromising the fire performance.
