Physical vibrations are indeed caused by moving trains, trucks, and other transport modes. The CIPS L3M6 module explains that these vibrations result from mechanical motion (e.g., train wheels on tracks, truck engines), transmitting through the ground or air. In supply chains, this is a notable environmental impact—e.g., rail freight near residential areas can rattle structures. The statement is false, as transport is a primary vibration source, a key consideration in LO2 for sustainable logistics planning.
