My version of the WP.

Set in the early 1980s, the Western Pacific is soon no more and the Armour yellow of the Union Pacific begins to take permanent root in the Feather River canyon. A two level shelf layout set in a 12x10' spare bedroom, the layout will model the 2nd and 3rd subdivisions (Stockton to Portola). Track is Atlas code 55 with minimum 15" radius and #7 turnouts and Digitrax DCC for control. Heavy focus on switching with plenty of mainline OPS if wanted.
