Thanks Gene. The previous owner did a real nice job of painting it.
==================
Intermittent lost of power fixed.
Several times the new decoder install on the Milwaukee F-7 Hiawatha train would lose power.
The 'keep alive' would keep the engine moving until power was regained.
Found the tender to be the culprit.
Usually the axles on brass engine have blunt ends whereas this model has pointed ends.
I'm guessing that is the main cause as all other parts were cleaned.
Drilled/tapped the tender truck for a screw and attached some wire from the screw to the axles cured it.
