perspective of someone riding a moving walkway through a dark tunnel or corridor

perspective of someone riding a moving walkway through a dark tunnel or corridor. The walkway itself is gray with black treads. On one side, there's a black guard rail with ventilation slits. Beyond the guard rail, the wall appears reflective, showing blurred images of foliage and other objects passing by. The environment is dimly lit, creating a sense of depth and movement as the walkway carries the observer forward. No people are visible, only the tunnel and the walkway itself.
