Fire brigade and rescue train (BLS)
The fire-fighting and rescue train (LRZ) from BLS AG (also called LRZ 04 ) is a rail-bound, self-propelled rescue vehicle that was procured with a view to the commissioning of the Lötschberg base tunnel .
The main tasks of the LRZ 04 are fire fighting and rescuing people in the Lötschberg base tunnel. However, it is also suitable for other fire-fighting and rescue work on or directly next to the standard-gauge route network of BLS AG and other Swiss route operators.
The LRZ 04 was put into service in 2004 and replaced the LRZ 76 that was procured in 1979. The SBB also procured a structurally identical unit, which however only has one rescue vehicle. This LRZ is stationed in Brig.
General
The LRZ 04 consists of an equipment vehicle, a tank fire engine and two rescue vehicles. The direction of use is oriented towards the Lötschberg base tunnel .
The arrangement of the composition (in the direction of travel):
- Equipment vehicle - fire fighting truck - ambulance I - ambulance II.
When in use, the LRZ 04 always drives in conjunction with all four units. While the rescue vehicles and the equipment truck have their own drive, the tank truck is the only vehicle that does not have its own drive.
The units are connected with a UIC screw coupling and have compressed air hoses for braking. In addition, a ring line and a train bus run through all units. The train bus connects the controls of the individual vehicles and enables operation from each of the four driver's cabs. The ring line is supplied with electricity from a generator. When the vehicle is not in motion, the ring line can be cut at the ends of the vehicle and connected to a stationary 400 V / 230 V power supply.
All three powered vehicles are powered by 2 power packs each (diesel engine with turbocharger, automatic transmission with built-in retarder and cooling system) in accordance with the EURO III standard. One axle of each of the two bogies is driven by cardan shafts. With an output of 315 kW each in the rescue vehicles and the equipment vehicle, the LRZ 04 can drive a maximum of 100 km / h.
The equipment vehicle and the fire truck form a non-separable unit (the fire fighting train), whereas the two rescue vehicles (the rescue train) can be separated from the fire fighting train during the (fire) operation and can leave the emergency site with the rescued.
The following operating modes are possible:
- Driving in a group (equipment vehicle + fire fighting vehicle + ambulance I + ambulance II)
- Driving in individual operation (ambulance I and II in shuttle operation)
- Driving in a master / slave combination (equipment vehicle with fire truck)
- Driving in a train (towing)
All four driver's cabs and both rescue containers are pressure-tight and have a breathing air supply that generates overpressure. In the driver's cab of the equipment vehicle and the tank extinguisher there are additional controls for fire extinguishing technology. Breathing air connections for the direct connection of breathing masks are available in all cabs and distributed throughout the train.
The train's entire supply of breathing air is around 2 million liters and is stored in 50 l storage cylinders at 300 bar pressure. The theoretical duration of use is at least 4.5 hours.
Distribution of storage bottles:
- Rescue vehicles 36 breathing air bottles each
- Equipment vehicle 36 breathing air bottles
- Fire truck with 24 breathing air bottles
Location
Initially the LRZ 76 and later the LRZ 04 were stationed in Spiez . The LRZ 04 has been stationed in the BLS intervention center in Frutigen since June 2007 . The joint use of the intervention center with the Frutigen fire department , which uses large parts of the building as a fire station , is unique in Switzerland .
crew
The team consists of 15 full-time operations managers from the BLS fire brigade, three of whom are on duty in Frutigen 24 hours a day, 365 days a year, in order to fill the positions of "Operations Manager Infrastructure Operator", "Operations Manager Tunnel" and " Operations Manager Special Base Railway Facilities". In addition, officers from the railway base fire departments in Frutigen and Spiez are available for section managements such as B. "Front", "Security", "Rescue" or "Fire" are available.
The lower management and the team consist of the railway base fire brigades Frutigen and Spiez. The BLS fire brigade always provides the on-duty emergency engine driver for the LRZ, who is constantly available in the intervention center.
All members of the fire brigade (AdF) who move out with the LRZ 04 have additional training as tunnel specialists. The prerequisite for training as a tunnel specialist is membership in a railway base fire brigade and the ability to wear respiratory protection.
The training to become a tunnel specialist comprises the following modules:
- Module 1: Training on fire-fighting and rescue trains (2 days) - detailed training on LRZ 04
- Module 2: Tunnel operations (2 days) - practical training at the ICST in the Hagerbach test tunnel
- Module 3: Training on the tunnel facilities and systems (2 days) - detailed training in the Lötschberg base tunnel
- Module 4: Management training (4 days)
In the management training module, police and medical officers from the cantons of Bern and Valais are also integrated into the training in order to train them to deal with major events jointly.
Alerting and operational readiness
As with all fire brigade operations in the canton of Bern, the alert is issued by one of the three operations centers of the Bern cantonal police at the same time using the systems commonly used in Switzerland:
- analog radio signal receivers
- digital message receivers
- SMT ( S ystem for M obilisierung means T elefon)
The driver on duty must begin to get the LRZ 04 ready to run within 5 minutes. The fire brigade BLS and the AdF of the railway bases put the fire extinguishing technology, the breathing air system and the rescue technology into operation with five AdFs.
The LRZ is required to be ready to drive out 15 minutes after the alarm has been issued with around 15 to 20 AdF.

vehicle
The LRZ 04 was designed on the basis of the Windhoff MPV . It is the combination of a fire fighting train consisting of an equipment vehicle and a tank fire engine as well as an ambulance train consisting of two rescue vehicles. The train is equipped with the Signum INTEGRA and ETCS Level 2 train protection system.
Equipment vehicle
The equipment vehicle is a self-propelled unit with a driver's cab built on one side, which was manufactured by Windhoff GmbH. Parts of the equipment come from Dräger Safety AG & Co. KGaA and Windhoff GmbH and Vogt AG (fire extinguishing technology).
The driver's cab is a pressure-tight cabin for the train driver, a radio operator and a fire-fighting engineer. A thermal imaging camera can be installed from the outside in front of the train; The image for the engine driver is transmitted to a monitor next to the driver's cab so that they can drive in the thick smoke.
Various communication devices enable radio communication with units of the fire and rescue train, the fire brigade, the rescue service, the train radio, organization radio of BLS AG and the telephone network.
The work module I / machine room 20 'contains a power generator and a compressed air compressor, the work module II / equipment room 30' includes various extinguishing and rescue equipment.
The fire extinguishing system has dispensing fittings for water and foam.
Tank pumper
The fire truck is a non-powered vehicle with brake equipment for coupling to a towing vehicle, with a driver's cab built on one side for controlling a coupled drive vehicle, which is always the equipment vehicle. Equipment vehicle and fire fighting truck are only separated for maintenance purposes. Josef Meyer AG (vehicle), Windhoff GmbH (driver's cab), Dräger Safety AG (breathing air system) and Vogt AG (fire extinguishing technology) acted as manufacturers.
The driver's cab and the communication equipment correspond to those of the equipment vehicle.
In addition to a 6-cylinder diesel engine (232 kW), the machine room also contains the units for dispensing water and foam from the 52,000 liters of water, 1,600 liters of foam compound and 100 liters of compressed air foam carried along.
In addition, a wide variety of fire brigade equipment ( mobile water / foam cannon , hose material, jet pipes, etc.) is carried.
The built-in fire extinguishing system has containers and, as with the equipment vehicle, dispensing fittings for direct dispensing of water and foam.
Emergency vehicles
The rescue vehicles are self-propelled units with a driver's cab attached on one side and a rescue platform on the opposite side. The two vehicles are coupled together on the platforms. The transition from one platform to the other is possible via a bridge.
Manufacturers are Windhoff GmbH (base vehicle) and Dräger Safety AG (rescue container, breathing air system).
The two driver's cabs correspond to those of the equipment vehicle and the tank truck, but have no fire extinguishing technology.
The communication facilities correspond to those of the equipment vehicle.
The rescue containers each have a main room with overpressure that is independent of ambient air and that is accessible through a lock area and offers space for 60 people (sitting / standing) or 40 people (sitting / standing) and 9 people (lying). In addition, equipment is used with respiratory protection and for the rescue and care of affected people.
