Sierra No. 28 Repair Project- Removing the Jacket

To access the boiler, the jacket and lagging must be removed.  Lagging is a kiln-like material that is wired and cemented into place, and encapsulated by a sheet metal shell.  The main purpose of the lagging and jacket are to retain heat in the boiler. On this project we will be replacing the lagging and jacket with new material.  The jacket will be preserved.
