These tickets are 2nd class tickets and only valid on that/those specific train(s) you chose when booking.
No refund or change is possible.
You can buy them up to 7 days in advance, but not later than 1 day before travelling.
How to book:
1. Insert your travel details here: http://bahn.ltur.com/index/ConditionSpar
"Hin- und Rückfahrt" means a return ticket, "Einfache Fahrt" a one-way ticket.
Insert your "from" and "to" cities and the date you want to travel on, also choose the number of travellers.
Erwachsene = adults. For those cheap 25€ tickets, any kids 6 years or above count as adults.
Kids of 5 years and under travel free and don't need a ticket.
Click on "Suchen"
2. On the 2nd page, check the box to the left of "nur 25 € Sparangebote" to get a filtered list of connections showing you only the 25€ connections.
3. In the now filtered list, mark the connections you would like to book and click on "Weiter".
4. You now have to give your personal details.
Under "1. Reisender" fill in the name, address, phone nuumber and e-mail address of the 1st traveller (the tickets will also be sent by e-mail to that e-mail address):
Anrede = Herr (Mister) oder Frau (Ms./Mrs.)
Vorname = first name
Name = family name, surname
Straße/Nummer: street and street number
PLZ = postal code
Ort = town, city
Land = country of residence
The USA is "Vereinigte Staaten", Canada is "Kanada", and the UK is "Grossbritannien" in the country drop-down menu.
Telefon/privat = your private phone number
Telefon / Mobil = your business phone number of your cell number, you don't have to fill in this field.
E-Mail = your e-mail address
"E-Mail bestätigen" = please write your e-mail address again, to be sure you have got it right.
All fields that have a * next to them have to be filled in.
Ditto for "2. Reisender" = 2nd traveller, if you are booking for two travellers, and so on.
5. Under "Identifikation für das Online-Ticket" you have to give the details of a credit card that one of the travellers will have on him/her on the train, to give to the train conductor to scan the magnetic band on it and therefore to see whether the card number is the same one as defined during the booking process.
Put a bullet to the left of "Kreditkarte".
To the right of "Kartennummer" write your credit card number.
To the right of "Gültig bis" put in until when that credit card is valid.
6. The area "Bezahlung" is about paying for those tickets.
You can either use the same credit card you defined above for identification purposes, or pay with an entirely different credit card.
"Kartennummer"= credit card number
"Kreditkarte" = type of credit card, e.g. MasterCard, Visa, American Express, Diners Club, JCB
"Prüfnummer" = the 3-digit CVC code on the back of your credit card
"Gültig bis" = valid until
7. Under "Reservierung" you can choose whether to add a seat reservation at 4€ per way and person to your booking.
You don't have to but it's advisable to do so so that you are sure you won't have to stand on the train.
8. Click on "Eingaben prüfen" to get a page where you can again check all your details, and if necessary go back to make changes.
If all is ok, go to the next page to pay for your ticket(s).
9. You can print the ticket(s) right away, but they are also sent by e-mail to the e-mail address of the 1st traveller which you gave during the booking process.
If you are printing on US letter size paper, be sure to check after printing that the bar code hasn't been cut off. If it has been cut off, buy some European-size A4 paper from any Staples store and print it again.
10. Take along the print out and the credit card (the one you defined as identification while booking) on your train journey.
If you are a group travelling together, you need only that one credit card for identifying your whole group.
Enjoy your train trip in Germany!
