According to the Croatian Railways (HŽ), certain changes will apply to international trains no. 158, 159 and 212 due to maintenance works between the Savski Marof and Zagreb Glavni kolodvor stations from 7 to 27 October:
- Train no. 159 runs only on the route between Dobova and Vienna; on the Dobova-Zagreb route, a replacement HŽ trainset runs.
- Rail replacement bus service is organized instead of trains no. 158 and 212 on the Zagreb Glavni kolodvor – Savski Marof route. The replacement bus service departs from Zagreb Glavni kolodvor station at 6.45 instead of 7.00, and at the Savski Marof station, passengers change trains to the international train no. 212. Passengers who continue their journey to Vienna, board the international train no. 158 in Dobova.
