More progress photos posted 4/18/19 to the FB UP Steam Club Page.

"...Big Boy's rebuilt air brake system and the cold water turbine that delivers water from the tender to the Elesco TP503 exhaust steam injector.

"The cold water turbine was designed for a 4000-class locomotive to deliver massive water quantities to the Big Boy’s boiler. In the upper-left corner you can see the fuel line running along side the firebox."

Enjoy!
