My whole layout has been done with Sunset Valley track. The code 250 looks great. Rail is sprayed rust color before installing. The turnout in the first picture is a Sunset Valley #8. I operate with battery so I use aluminum rail to save some bucks. Turnouts are nickel silver.
This is a little off topic, but Paul, those are some beautiful photos of your layout!
Seeing the rolling stock and RS3s, I can see why you were interested in doing the San Joaquin Daylight. BTW I went ahead with Aristo heavyweights and USAT streamline cars for my San Joaquin Daylight. I haven't seen them together yet so have my fingers crossed on the color match....
I do think the code 250 really adds to the overall effect for standard gauge. I'm using code 215 Llagas Creek on my indoor 1:20.3 layout.
I use Sunset valley rail and Accucraft tie strips. I just happened to like the appearance of the Accucraft ties a bit better; but, both makes are first-rate products. You can't go wrong with either. And I really like the more prototypical appearance of code 250 rail.
