The modifications enable trains from Groningen to reverse at Weener station in Germany. Services between Groningen and Leer have been interrupted since December 2015 due to damage to the Friesenbr├╝cke bridge across the Ems river following a collison, and is yet to be repaired by DB.

Test running took place on October 28-29 between Nieuweschans (Netherlands) and Weener to check the modified signalling situation. An hourly passenger service resumed on October 30.

The bus service, which operates between Groningen and Leer, will continue as a two-hourly service, with a 55-minute journey time. The bridge should be repaired and reopened for train operations in 2020.
