You shouldn't necessarily make a special trip, but if you happen to be in the vicinity of the Alamodome, check out the former rail depot Sunset Station. Originally the Southern Pacific Railroad Depot and the city's Amtrak station (which moved next door), and a stop along the Sunset Limited line between San Francisco and New Orleans, the station has been fully restored to its old glory, complete with stained-glass windows and a colorful, bold interior. Don't overlook the vintage 1916 steam engine either. The station is usually hired out in the evening for private events, but it's open to visitors during the day. Look on its website for a historical walking tour.
