Hello! I am travelling from Prague Hlavni Nadrazi to Budapest Keleti in two weeks and I have already chosen my trains on the Rail Planner app. However, on the ÖBB website it says that there are some changes in the route due to construction work. Has anyone used this route and knows what is happening? Are the trains working?
Thank you all! 
Yes, trains run-with delays, as there are very long lasting works to double/quadruple the tracks on the busy sector east (vostok) od Prahy. This may mean delay on end of trip-or often also much earlier departure to be able to maintain normal times beyond works.
Again: it should be blind obvious that planner of railway there=cd.cz is the 1st to look at and give advice. For the daytime trains/vlakove RES is only optional. Double check again the day before.
As
Here is some useful information from the experienced travellers in the Community regarding both planning, reservations and activation of pass and travel days.
Planning
The rail planner is normally not up to date, as it only is updated once a month, so to be sure of the time table you better check the timetable and availability on the websites of the national railways. The bigger national railways, like DB (Germany) SBB (Switzerland) and ÖBB (Austria) cover several countries.
Reservations
The advice from the experienced travellers in the community is to use other ways to make reservations than the Interrail/Eurail website. You can look at the guide in the link:
https://community.eurail.com/train-connections-reservations-47/how-to-get-reservations-105
If you, after having looked at the guide, have questions about how to make specific reservation, please give your travel details (departure date, time and route) preferably in a new topic, and you will get advice.
Please note that Interrail/Eurail charges an extra fee of 2 EUR per person and train in addition to the fee for the seat reservation.
Activation of pass
During the activation process, when you choose the start day of the validity of the pass, the first day of the validity period is automatically made a travel day, even if you don't enter a journey, the advice is therefore not to activate the pass before the first travel day as you only can deactivate the pass before 00.00 on the day the validity starts. If your travel plans change in the last moment you will loose travel days if you have activated the pass in advance.
It can be wise to make a test and activate the pass with a start date well in the future and then deactivate the pass immediately, just to see that everything works.
Activation of travel day
The advice from the experienced travellers in the community is also never to activate a travel day, that is connect a journey to your pass, until just before boarding the train, otherwise you might loose a travel day if your travel plans change in a late stage You can't delete a travel day in the past. A travel day can only be deleted until 23.59 CET the day before the travel day.
