Grinding is increasingly used by railways in order to improve track quality, reduce track forces, remove defects, modify contact geometry and reduce rolling noise. Wheel tread maintenance means machining-off of material in a workshop lathe. Aspects of these matters are considered in the EU project...
Toy railway track has points with suspended moving vehicles driven by an airflow. The rail is made as a hose from thermoplastic material in which a steel ball is fitted which corresponds to the hose's hollow profile. A magnetic plate fitted to the vehicle chassis frame which carries a cabin...
