This last summer Hanecki had captured Lenin’s imagination with his plans to found a trading company of his own in Europe, or take a partnership in some existing firm and make guaranteed monthly remittances to the Party out of his profits.

At one level, that may mean tailoring services to demand and introducing vehicles that are genuinely lighter in weight. At another, calculating the energy and emissions of track renewal - whether steel rail, concrete sleepers or mining ballast, crushing, shipping using dirty fuel, and re-handling it before finally placing and maintaining with diesel equipment. And then shortening its life though the wear and tear of tamping to counter the effect of elephantine passenger vehicles.
