How does a train line run from the United Kingdom to Germany?
A friend of mine who lives in England told me that sometimes on his lunch break, when he feels for good tasting fried chicken, he would board a train and in a matter of minutes he would reach Germany, eat his lunch and he would head right back. What is confusing to me is when I looked at the map, I saw that they are separated by a body of sea water so what I want to know is how does the train line get across? Also, is it true that he can arrive there and back in limited time and is it really cost effective?
