One hand to the tripod, the other to the cable release... ;-)
Given by the speed at which people can walk stairs (those in the picture seem to have traversed two to four steps over the course of the exposure), I'd guess at a exposure time of two seconds for that picture, perhaps a bit less if the photographer caught them running for a departing train, but nowhere near being hand-holdable. As it has a rock-steady background, it must have been shot on a tripod (or with a tripod substitute, e.g. pressed or clamped to the railing). If handheld, the photographer must have used heavy duty electronic stabilization.
