San Francisco MUNI Skoda ETI Trolley Bus #5483 on Route 30 - Stockton

It's sound of its traction equipment control not the axle or motors

The sound's probably an older style VVVF motor.

@bearchoirfan It's not the sound of motor, but it goes from the axle Rába from hungarian production.

The "please hold on" address is referred to in Hong Kong's subway trains as "please hold the handrail tightly", if I'm not mistaken.

sounds like a Skoda 15TrM

Dayton Ohio's GDRTA (was MVRTA) has the same SKoda Model 14TR trolley buses. As a matter of fact, Dayton was the test bed for the 14TR and MUNI ordered theirs after getting affirmation from MVRTA.
