Itinerary from Belgrade to Budapest

The "High Speed" train is scheduled to hit speeds of 100mph in Hungary! They say the full trip is 2:40 to 3:17 but I dont believe that counts borer control. I would guess another 40 minutes until I see somehting different. Some reports are there will be two trains at first ramping up to 6 a day, other reports just say 6 a day. I havent seen a start date. They said Feb or March. Well, Feb doesnt look like it will happen. If you get some information, please post it.

Day 1 Belgrade to Subotica (you could take an earlier train to Novi Sad then join the high speed train from Novi Sad)
Day 2 Subotica to Szeged
Day 3 Szeged to Budapest

But it all depends on the times of the trains. Dont know. I think so much in such little time is iffy for my style as you may only get a few hours in each city, but each to their own. When you have the train schedules then you can figure it out. Maybe if you have more than 4 full days planned in Budapest you can spend more days on the trip?

Here is the most current news that I can find. Please note the stops that the train will make.. https://dailynewshungary.com/budapest-belgrade-ticket-dates-timetable/#budapest-belgrade-railway-where-will-trains-stop

Thank you for your quick responses. I like the slower approach especially with train uncertainty. I will stay tuned to train changes but plan on just Subotica and Szeged. I have my 2 week trip divided as follows: 3 days in Sarajevo, 2 days in Belgrade, 3 days in Subotica/Szeged, and 3 2/2 days in Budapest.

Correction: 3 1/2 days in Budapest
