Seaboard M - - - Yes, the O5's were passenger haulers (I traveled behind O5b #5632 pulling an excursion in 1961, doing 90 mph along the Mississippi R in WI). But, they were also dual service freight haulers, quite comfortable pulling 100 freight cars at 60 mph. Great locomotives !
BR Web - - - Kind of an interesting story behind the two stainless steel streamlined 4-6-4's on the Burlington. One (#4000) was an existing locomotive, that received a streamlined cowl (1937). The other (#4001) was built new (1938) at the W. Burlington shop. The Burlington opted for steam locomotive back-ups for the new, diesel Zephyr fleet because the same horsepower could be obtained at a cheaper price with steam locomotives !! The two engines were de-streamlined in 1941, as the beautiful E5's had arrived in 1940, so the Zephyr fleet was adequately covered.
