It hasn’t been discussed much, but there will be at least one major benefit from the video-game revolution: the imminent death of the toy-train cult. Within a generation (or two at most), we will finally see the last of these model-railroading freaks and their miniature landscapes, their meticulously reproduced Lake Wobegons, and their hand-painted, perfect-scale Lionel cabooses. In this unsentimental, Doom VII-drenched near future, train sets will be shunned by even the most gullible tots, and they will crumble like tiny ghost towns on the shag rugs of suburbia, as 2048-bit Sega renders their unplugged, electric labyrinths—so awkwardly did they try to imitate reality!—as obsolete as cave paintings. Good riddance. Until then, there will continue to be sporadic gatherings of cult members in events like Greenberg’s Great Train, Dollhouse, & Toy Show from 11 a.m.-5 p.m. today and 11 a.m.-4 p.m. tomorrow at the Capital Expo Center, 4320 Chantilly Shopping Center, Chantilly. $5.
