In western Ukraine, some 1,100 train wagons carrying grain are stuck near the main rail border crossing with Poland, unable to transport their cargo abroad.

They are just some of the 24,190 wagons carrying various goods for export, including vegetable oil, iron ore, metals, chemicals and coal, that were waiting to cross Ukraine’s western border as of Tuesday, according to data from the state-run railway company that hasn’t previously been reported.

With war raging along the country’s southern coast, and its main ports blocked off by Russia's invasion, Ukraine is struggling to export its grain and other goods, according to government officials and industry insiders. But as Kyiv looks for alternative export routes by land, that effort has been hampered by logistical challenges and red tape, industry officials and commodity traders say.
