Trouble buying tickets on Hungarian train site

Lots of people seem to have trouble, so I believe you. But I've been lucky and havent. Do this, wait 24 hours to make sure their old Russian computers have processed your request and try again. Then, if you still have problems, try and change your password. Failing at that, call customer service. I spoke to them once and they were very professional

Or try Loco2 (https://loco2.com/) or Trainline (https://www.thetrainline.com/?redirected=true)

The others may be okay too. But check the prices.

On the MAV site you can get the discounted rate even the night before.

James is right. On the Hungarian train site, you can get the discount ticket for 13Euro one way from Budapest to Vienna.

I found the MAV site highly confusing as well. I was looking at Budapest to Vienna and it showed me different train times based on the ticket price I wanted to pay. And first you had to put in the passengers' birth dates. Then came the prices, click on a price and get one set of times, click on another price and get a different set of times. And the times aren't even the same as the ones I found when I researched it on DB. I'm planning to just go find the MAV office in Pest that is mentioned in Rick's book a few days before we travel and buy the tickets in person. I'm hoping this is going to be a good solution. The book says the train station office has long lines but the one in Pest (wherever that is) is quick.

And, I'm not sure the ticket office is still open in Pest. Maybe yes, maybe no. I have never seen a long line at the ticket office at Keleti. Going there also gives you the opportunity to see an interesting old train station and learn your away around before travel day. It is conveniently accessed on the metro.

My Updates for buying ticket on Hungarian train site:
James,
As you suggested, I waited a day, then went back to the site, it let me login and I purchased the tickets from Budapest to Vienna for 13 Euro one ticket. They emailed me the 10 digit code and I will get the tickets at Keleti when I get to Budapest.

Glad it worked out. Now you have to deal with the ticket machine at Keleti :-)

Will the vending machine be hard to deal with?

Noooo, just kidding... :-)

Hahaha, oh ok. Thanks again for your help.
