In the run-up to Sunday’s crucial election, the Guardian took a long journey through Europe’s heartland to talk to voters

Creaking, overcrowded, neglected, Germany’s railways, once a source of national pride, have taken a battering to their image in recent years. Amid wider concerns about the health of Europe’s stagnating largest economy, the state of its trains has become something of a metaphor for a more general sense of malaise.

On Sunday Germans will go to the polls in one of the most important elections in recent times, with an emboldened far right hoping to more than double its share of votes. In the run-up, the Guardian travelled more than 850 miles on trains across Germany to hear what its citizens have to say about the state of their nation.
