CaptionMay-June. A driver tops up an OL-49 locomotive with oil before a run. The locomotives that ply the route from Wolsztyn to Poznan in western Poland form one of the last scheduled steam-train services in Europe. Huge OL-49 engines, more than half a century old, consume up to 18,000 liters of water, three tons of coal, and eight liters of oil on the 180-kilometer round trip. It takes one-and-a-half hours for the drivers to ready the train for the journey, stoking up the boiler to build up steam.
