Some places are just a place. Some places are a journey. Three days out of Vladivostok, the westbound Number One train lumbers across the Siberian outback like a team of driven oxen. The train’s nineteen hulking, crimson and blue cars creak and groan as they throw themselves forward at speeds not much different than when this track was hacked through half a continent of nearly impenetrable forest and bog in the days of the last tsars a hundred years ago. Three days aboard this beast-machine has gotten us deep into Russia, beyond a hundred ragged towns with names like Obluche, Zilovo, Spassk-Dalny, and Shimanovskaia, nearly every one of which, it seems, was established as a gateway to the mines and prisons of the tsars’ exile system or of the Soviet Gulag, and which generations later still seem more outposts than towns. Clusters of log homes and cabbage patches line the tracks, ashen concrete apartment blocks rise beyond, and doleful bands of kerchiefed women at each station peddle pirozhki and salted fish, unshelled pine nuts in newspaper cones, and hard-boiled eggs cradled in baby carriages. All are thinly tethered to Mother Russia by the lace curtains and flowers in every window, the stubbornly proud train stations, and these two thin steel rails. We’re three days deep into Siberia and, it seems, no place at all. Brown fields spread from the outskirts of the settlements, blotted at random intervals by abandoned and half-collapsed factories, and through the emptiness between passes an almost unchanging plain coursed by wandering rivers and deep thickets of dark pine and fir, wispy white birches, and larches glowing a brazen yellow. Dawn this morning revealed the regional capital of Ulan-Ude, the latest in a string of sullen cities of cinder blocks and smokestacks. This afternoon will bring us to the tarnished old imperial city of Irkutsk, first settled in the seventeenth century and later the destination of some of the luckier of the tsars’ exiles. We’re 3,700 kilometers west of the Pacific, 5,500 kilometers east of Moscow, 250 kilometers north of Mongolia, and south of nowhere.
