Security footage from inside the train shows Szymanski sprinting down the aisle of a car while passengers duck and cover in their seats and in the center aisle. The train's forward-facing camera captured the impact, as the train smashed into the rear quarter of the truck scattering vehicle parts, lumber, and construction material. Some of the lumber in the truck smashed through the train windows, but thanks to Szymanski's warning the seats were empty.
"We can say he almost certainly saved passengers from injuries," said Krzysztof Ryfa, a director of the railway that employs Szymanski.
According to Eurostat, a 2014 study on railway safety showed that Poland was one of four EU member states, along with Germany, Hungary, and Romania responsible for more than half of the 1,928 people killed or seriously injured in railway accidents.
