Machine translation from one of the pdfs:
The fire and rescue train has a top speed of 100 km / h and can move trailer loads of 940 tons on an incline of 27 per mile.
Not sure how a 153 would compare though. I'm guessing SBB is probably planning for freight breakdowns. (I think they may have locomotives on standby too)

machine translation of one description:
326 tons of flexibility
The latest generation of fire and rescue trains consists of a tank fire truck, an equipment vehicle and two rescue vehicles. The drive is carried out with two diesel power packs (6 cylinder turbocharged diesel engine from MTU, particle filter, turbo gearbox with built-in retarder and cooling system) according to EU emissions standard IIIA, each with an output of 390 kW via the two rescue vehicles and the equipment vehicle. The fire and rescue train
has a top speed of 100 km / h and can move trailer loads of 940 tons on an incline of 27 per mile. The train's total breathing air supply is 1980,000 standard liters and is stored in 132 storage bottles, which have a volume of 50 liters, at 300 bar pressure. Connections for the supply of breathing air are available at various locations in the interior and on the platforms. Separate respiratory masks or the portable respirator with transmitter and slave hose can be connected to it. All driver's cabins are pressure-tight and have a breathing air supply that creates excess pressure. A control panel for the fire extinguishing technology is also installed in the driver's cab of the equipment vehicle and the tank fire engine.
