Stadler and ÖBB have unveiled a new trimodal rescue train at the ÖBB training campus in St. Pölten, Austria.
Stadler is set to deliver 18 of these multifunctional, low-emission firefighting and rescue trains to ÖBB-Infrastruktur AG (ÖBB).
Named the Servicejet, these trains will be stationed at strategic tunnel portals across Austria to assist firefighters in emergencies.
The new rescue train is 68 metres long and has a top speed of 160 km/h in both directions. It features a trimodal electric hybrid drive system that can operate using the overhead line, traction batteries, and diesel generators.
This versatility will allow the rescue train to operate in all environments, including navigating through smoky tunnels, reaching fire sources, rescuing individuals from damaged trains, towing trains, combating fires, and evacuating safely from danger zones.
“Our new Servicejets enable us to provide assistance even faster than before. They provide more power in a larger operational area. The new concept also enables a reduction from 21 to 18 vehicles.”
Each of the new trains can accommodate over 300 people during emergencies. The train’s three cars are interconnected, providing uninterrupted access throughout. Eighteen seats are equipped with SCBA brackets for firefighters, while an HVAC system with special filters protects occupants from smoke gases.
The entire train is pressurised, maintaining a slight overpressure inside to keep smoke out in tunnel environments. Additionally, the driver’s cab is safeguarded by an external water spray system.
The rescue train can also be equipped with themed roll containers that transport essential firefighting equipment like portable pumps, forest firefighting gear, breathing apparatus, and protective suits. These containers, preloaded at ÖBB Infrastruktur support points, can be swiftly loaded and unloaded using built-in lifts, ensuring rapid response to various emergencies.
For firefighting, the rescue train is outfitted with two distinct extinguishing systems: a high-pressure system (100 bar) for generating fine spray mist to cool tunnel walls or moisten track verges, and a normal-pressure system (10 bar) for conventional firefighting. The train carries 40,000 litres of water and 1,200 litres of foam concentrate.
What’s more, jet fans on the roof help disperse water mist and create counter-pressure in smoke-filled tunnels, aiding in evacuation efforts. Additionally, powerful searchlights and thermal imaging cameras enhance visibility during search and rescue operations.
“With the launch of the rescue train, we have put a highly innovative concept on the rails that meets ÖBB Infrastruktur’s specifications and satisfies all the customer’s quality and safety requirements.”
The development and production of the rescue train took place at Stadler’s Swiss sites in Bussnang and St. Margrethen.
The Servicejet is a bespoke solution for ÖBB, also approved for use on the German rail network. The vehicles will debut during the opening of the Koralm Railway, which includes a 33-kilometre tunnel.
