Prosecutors delivering their closing arguments on Tuesday blamed the tragedy on a heater unsuitable for vehicles.
Some 155 people were killed when a fire broke out in a funicular train that was going through a tunnel up to a ski resort on the Kitzsteinhorn mountain.
Among the dead were skiers from Japan, Austria, Germany, the US and a Briton.
Sixteen people, including officials from the train company and transport inspectors face charges of negligence.

They pleaded not guilty.
In her summing up, the State Prosecutor Eva Danninger- Soriat said the fire had started in the cheap and inappropriately installed heater that was not designed for trains.
She said there had been a serious lack of fire safety measures.
The defence is due to give its final summing up on Wednesday, and a verdict is expected in February.
