We are planning to go from Prague to Krakow by a night train. So we've been looking for trains on the DB Bahn website and we've found one which departs on 7May 20:17 in Prague and arrives on 8May 07:14 in Krakow. But there's a reminder "runs not every day" for this train.
So I wanna know if the train will be really available on that day and are the train schedules listed on the DB Bahn websites confirmed for May??
Also the web listed both EX 403 and R 403 as the "products" but indicates that we don't have to change trains. I'm a bit confused. So which exactly am i going to take?
And will there be any people coming onto the train to check our passports when we cross the Czech-Poland border at night?
This would be my first time in Europe so i may sound a bit naive. Sorry :P
