Welcome to BVEStation.
I was also considering doing the R11/R34 at one point, but then dropped the idea. I do however, have several texture shots.Do remember, the R11/R34's seating layout is just like that of the R16 with longitude and cross seats.
Good start. This will go great with CT1660's package. Remember to make both a GE and Westinghouse version for the final product, since CT1660's trains will also come with both versions.
