The question for history is not only who should be driving the engine, but where. The Prokopoviches have something to fear, and they police these suspect, illegal branch lines, all the while insisting they do not exist. Onto such tracks the revolutionaries divert their train, with its contraband cargo, unregisterable, supernumerary, powering for a horizon, an edge as far away as ever and yet careering closer. Or so it looks from the liberated train, in liberty’s dim light.
