Abstract: The invention relates to an elevator system comprising at least two elevator cars adapted to travel in respective separate hoistways of the same building. The at least two elevator cars have at least two different rated speeds comprising lowest rated speed and a rated speed higher than the lowest rated speed. At least each said elevator car with the rated speed higher than the lowest rated speed is provided with an electronic overspeed monitoring equipment configured to stop the movement of the elevator car, if the speed of the elevator car meets an overspeed threshold. The overspeed threshold is decreasing towards at least one end terminal of the hoistway. Each of said separate hoistway of the building has a bottom end terminal space with a substantially equal height and/or a top end terminal space with a substantially equal height. The invention relates also to a process for providing an elevator hoistway arrangement comprising at least two separate elevator hoistways and to an elevator hoistway arrangement obtainable with the process.
