Wagon for rail-bound vehicles

The innovation concerns a wagon for rail-bound vehicles for the accommodation of people to protect them from a harmful atmosphere.

Such a wagon is described in the DE-Z: Drägerheft No. 221, June/October 1952, page 4745.

Such wagons are intended for use on rail lines in conjunction with a rescue train and provide, for example, an atmosphere protected from dust or pollutants for the work personnel during tunnel work, or serve as rescue trains to provide care for people who, for example, need to be protected from a harmful gas atmosphere due to accidents or other stays in tunnels. They are particularly suitable for use in underground railways, where, due to the long tunnel stretches, there are hardly any other access options to possible accident sites than by rail.

The well-known wagon is a converted standard passenger car in which ambient air is sucked in through a filter and purified and released into the interior. However, the filter capacity is only sufficient for a short, limited stay, with a significant portion of the purified atmospheric gas escaping unused into the environment through the existing leaks in the doors and windows.

The aim of the present innovation is to improve a wagon for rail-bound vehicles of the type mentioned so that a protective atmosphere can be created and maintained over a long period of time within the wagon without any significant loss of unused breathable gas to the ambient atmosphere.

To solve the problem, it is planned to mount a pressure- and gas-tight structure on a chassis.

The main advantage of the innovation is that the loss of breathable gas can be reduced significantly, since only the gas used for breathing needs to be replaced. People staying in the interior are protected from harmful substances that could otherwise enter through leaks. This makes it possible to stay in the protected atmosphere for longer periods, so

that more complex, longer-lasting rescue measures and medical treatment can now be carried out in the wagon itself. The pressure-tight structure enables the easy generation of internal pressure so that minor leaks that go unnoticed or occur during operation or when leaving the interior can be compensated. This increases safety during use.

Due to the economical gas consumption, it is possible to connect an autonomous gas supply system to the structure to supply the interior with breathable gas. This can, for example, consist of a battery of high-pressure gas bottles that are housed in a separate frame. This gas supply system can also be used to supply appropriate medical devices, such as ventilators or inhalation devices.

It is particularly useful to provide containers as a superstructure for the chassis, which are easily replaceable and can be attached to the chassis using suitable tools. This makes it easy to equip the chassis with containers with different contents depending on the requirements of the situation. For example, one container can contain equipment for medical care, while another container is only used to accommodate people in a protected atmosphere. Both containers are placed on a common chassis and attached to it and can be connected to one another via an intermediate corridor or are connected to form a complete unit.

To ensure safe entry and exit of the structure, a lock chamber is provided at the entrance. This prevents the ingress of harmful substances or unwanted truck dismantling in the interior.

In order to use the wagon as a control car for an auxiliary train, the body has a turning head control unit on the front side in the direction of travel for the _operation of the drive vehicle. This allows

An embodiment of the invention is illustrated by means of the schematic drawing and explained in more detail below.

The only figure shows an auxiliary train with two wagons 2 coupled to its locomotive 1. Each wagon 2 consists of a chassis 3, which carries two containers 4 as a superstructure. The containers 4 of a chassis 3 form a unit, with each of the containers having access via a lock chamber 5. Both wagons 5 are connected to one another in their opposing containers 4 via an intermediate corridor 6. The front of the container 4 at the end of the train has a turning head control unit and an associated workstation for the train driver (not shown in the figure). Each wagon 2 has a gas supply system 7, which consists of several high-pressure gas bottles 8 with the associated connections.
