Upon arriving at the train station, we entered the front doors and found the ticket window on our left, with a small waiting area in the middle and restrooms and a restaurant on the right. We went straight to the ticket counters and requested two tickets to Bratislava... the friendly lady at the counter carefully began asking us questions, but we couldn't figure out what she wanted to know. Finally, she printed out two itineraries on the front and back of a half sheet of paper--one was to "Bratislava N. Mesto" station (95 km, 0 stops, 126 SKK or 4.10 USD) while the other was to "Bratislava hl. st." station (120 km, 1 stop at Nove Zamky, 146 SKK or 4.75 USD). With our limited understanding of the language and a basic travel guide, we finally realized Nove Mesto was the new town, just like in Prague. We also figured out that "hl. st." was hlavna stanica, or the main station, which was near the old town. Tickets in hand, we paid our 5 SVK to use the restrooms, then grabbed lunch at the pub while waiting for the train. Our train departed at 1305 from the first platform and we arrived in Bratislava around 1522 after a 5 minute stop at Nove Zamky to change trains.
From Komarom, Hungary, you can walk right over the bridge to Komarno. Of course, you have to go through the border control point, which is a breeze. It's about a 10-minute walk to the center of town then about 5 more minutes to the train station.
If you are wherever in Europe,the best thing you can do is to get to Budapest,the capital of Hungary or to Bratislava,the capital of Slovakia.When you are already in Budapest,you can take train and get right into Komarno.It takes about an hour or so.
From Bratislava it is better to take bus.It takes from hour and a half to two hours and a half,depending on the type of the bus link.
Komarno is not too big.While you are in the centre it is possible to walk.If you want to get to further parts you should either take a taxi,rent a car or bicycle,or take bus.But i would not recommend taking a bus,because they are not reliable at all,and they go very rarely.
If you get lost ask.Keep on asking in english.Although some people might not look too helpful you'll find somebody speaking English,or maybe other language beside Slovak,Hungarian and Czech.
