Czech Railways website & train Prague-Budapest

That was unfortunate! You'll have to get a refund on the ticket and replace it for the train you really wanted.

Be sure to include those hard-to-spell Czech words meaning "Return for replacement" to get you to the exact page you want.
Cheers!

Thanks @Kenko! I looked again at ticket & Google translate. Things seem more in order {fingers crossed}. Though there is some mystery to me where some of the numbers are coming from.

I think they come from the Gremlins living in our mobile devices!

There is a departure from Praha hl n around 9 AM (09:12) getting to Budapest at 16:20, a direct connection. The other departures require train changing one or more times. This 09:12 departure is on EuroCity (EC) train.

If you want the night train option as Budapest is a major night train hub in east-central Europe, that's available too, a direct shot to BP arriving at a decent hour. If I were doing this route, day or night is quite satisfactory, ie, direct connections, absolutely no problems. I would most likely take the night train option as to squeeze out another traveling day.

Your google converted it to East Coast time zone. Hilarious. So your train really does leave at 3:12 am East Coast time.

But I would have flown. Faster, less boring. But 3x the price of the train.

Thanks all!
And wonderful job solving this Mystery, Mr James E. Thanks very much

Its happened to me. Sometimes computers are too smart for us simple folks. Of course I am only correct if you do actually live on the East Coast (and your computer knows that).

It was the Gremlins in your cell phone!
