A Work in Progress

Our company N-Scale railroad is like most, A Work In Progress.  We are attempting to model the Coastal Division of the Southern Pacific Railroad between LA and San Jose.  The railroad main line is about 8 scale miles incorporating LA (staging) Oxnard, a siding at Ventura, Santa Barbara with a scratch built station and a large yard and engine terminal.  Moving on West railroad meanders across the bridge at Gaviota State park then on to the yard at San Luis Obispo (SLO).  Once the helpers are removed at SLO the train goes down a large helix and arrives at Soledad then in to staging at San Jose.
