A woman crouches down in the doorway of a blue and yellow train at a station in Kyiv, Ukraine’s embattled capital city. Her husband stands on the platform below and cranes his neck up for a kiss that both hope will not be their last.

As the train door closes, the woman holds up their 2-year-old son and he smiles and presses his tiny hand against the smudged window to wave goodbye to his father, who is staying behind to fight the Russian invaders.

Nearby, a grandmother reaches out to bid farewell to her daughter and grandson, who are on the train headed toward the border with Poland. She backs toward a wall of the train station and is soon overcome with emotion. She places her hands over her mouth, squeezes her eyes shut tight and lets the tears fall.
