Yardway describes the model as suited to high-speed lines, main lines, open track and level crossings.<\/p>\n<p>Its operating range spans light cyclical intervention, preventive reprofiling and heavy corrective grinding. Forty-eight independently powered grinding positions provide the installed grinding capacity, while onboard measurement supports profile control and work verification.<\/p>\n<p class=\"rgw-note\"><strong>Configuration note:<\/strong> SPENO machines are customised for the customer and network.
