passes are obtainable online or through your travel agent. While
these are all varied from unlimited / global tickets to 5 -
15 days travel within 2 months etc., separate tickets from each
country for example Swiss Pass, French Pass, Italian Pass are
also available and definitely worth looking into.
with limitations can restrict the spontaneity of your trip so
be mindful of this when buying a ticket.
things you need to be aware of are :
with most prearranged tickets, reservations and some supplements
do apply on most international trains and high-class national
trains. For example in Switzerland and Germany particularly,
the quality of train travel is very, very high and you do
get what you pay for even although it can be expensive. This
is where a Eurail for example is very much worth its price
if it covers these more expensive countries.
