A sliding step for a public transit vehicle, comprising:
- a tread plate including two lateral arms, a tread surface located between the lateral arms, and at least two rollers at each lateral arm to run on a track attached to the vehicle,
- wherein the tread plate is configured to be horizontally extended or retracted by a drive,
- wherein at least one of the lateral arms is formed in two portions, the two portions including a lateral arm assembly portion and a sensor arm assembly portion, and the lateral arm assembly portion and the sensor arm assembly portion each including at least one roller;
- wherein said at least one of the lateral arms includes an offset section which includes a strain gauge element to detect deformation, and the offset section is located between the at least one roller of the lateral arm assembly portion and the at least one roller of the sensor arm assembly portion.
A sliding step as defined in claim 1, wherein at least one roller of at the least one of the lateral arms is a profile roller.
