NASHVILLE, TN—The acquisition of new boiler tubes and flues has marked another major milestone in the restoration of Nashville, Chattanooga, and St. Louis steam locomotive No. 576, bringing the future Middle Tennessee rail attraction one step closer to operation.
“With boiler work nearing completion, the installation of the tubes and flues will be the last step before we begin filling it with water for the required hydrostatic pressure tests, which will pave the way for a steam test and eventual operations,” explained Shane Meador, President of Nashville Steam. “We were able to make this purchase thanks to the strong support from our generous donors.”
The boiler tubes transfer heat from the locomotive firebox through the length of the boiler, which generates steam and is then used to propel the locomotive and operate its various appliances. This steam, once it leaves the boiler, is sent through an additional array of piping that “superheats” the steam, making it more efficient by converting the remaining water droplets into dry steam and therefore gaining additional heat energy before it reaches the cylinders to provide the energy to move the 25” diameter pistons that power the 70” driving wheels.
Initial inspection of the superheater units revealed that the bottommost row had not been properly blown out and the remaining water had frozen and burst the piping from its time displayed in the park. The remaining superheater element rows appear to be in good condition, but hydrostatic testing to confirm will begin by the end of the year. As Nashville Steam’s dedicated team continues reassembling the 1942 locomotive, the superheater tubes will be needed for installation between the hydro and steam test, which are planned to occur during the spring and summer of 2025 respectively.
A new matching grant has been announced in time for Giving Tuesday. Between now and December 6th, donations will be matched dollar for dollar to raise $25,000 for the new superheater unit materials. Donations can be made online at nashvillesteam.org/donate or by mail at 220 Willow St, Nashville, TN 37210.
“Our supporters have continued to step up year over year, and this sustained support is at its most important as the restoration nears completion,” stated Meador. “Our crew is not only working on finishing the 576, but also laying the groundwork for operations in Middle Tennessee, building our partnership with the Tennessee Central Railway Museum, exploring real estate development opportunities, and studying the kinds of programs and offerings that will enrich our region with authentic Nashville history. The need continues to expand our volunteer, donor, and support base to bring Nashville’s newest attraction to life. Will you help?”
