NO, TRAIN (truck, streetcar, trolley, etc) VIBRATIONS CANNOT CAUSE CRACKING IN ANY TYPE OF CONCRETE (DRIVEWAYS, FOUNDATIONS, ETC). No, train vibrations do not cause cracking in houses (sheetrock, stucco, etc) that are more than 20 to 30 feet away from the tracks. However, train vibrations easily felt by people and can cause glasses to shift on shelves, pictures to shift on walls, and cause vibrations within a house that is easily felt. There is a very good manual on train vibrations issued by the US Dept of transportation (available on the web). The europeans have strict standards on train vibrations. These are designed to reduce human annoyance only. The level those standards require are orders of magnitude less than the level necessary to cause cosmetic damage to buildings.
