Deutsche Bahn is also holding talks with the smaller train drivers' union GDL.
Both unions want a 7.5 wage increase and also have demands on working hours and holidays.
Deutsche Bahn, which said it had offered a 5.1 percent wage rise in two stages and a one-off payment of 500 euros, said EVG's decision to break off talks had caused a "completely unnecessary escalation".
"To leave the negotiating table with this offer is incomprehensible and unnecessarily unsettles our customers in the middle of the Christmas period,' said Deutsche Bahn human resources head Martin Seiler in a statement.
