To serve this rapidly expanding market, TTX provides numerous car types for the transportation of blades, towers, nacelles, hubs, and other wind power generating equipment. Moreover, TTX Company's engineers possess substantial expertise in modifying railcars for this service in conjunction with engineering firms and wind turbine OEMs who design and manufacture the fixtures that apply the components to the railcars. For instance, TTX converted hundreds of 89-ft flat cars and former intermodal spine cars (each spine car is at least 260-ft long) to handle wind turbine blade fixtures. Likewise, these and other cars transport the tower sections as well. Additionally, TTX Company’s large fleet of heavy duty flat cars, bulkhead flat cars and 89-ft, 110-ton flat cars are all suitable to carry heavy nacelles and hubs.
