Simplify the following text for a Grade 7 native English-speaking person.
Original: Travelling to and from West Berlin by road or train always required passing through East German border checks , since West Berlin was an enclave surrounded by East Germany and East Berlin .
Simplified: West Berlin was called `` Berlin ( West ) '' by the West Germany government , and usually by the East German government . The east German spelling suggested that West Berlin was not really part of `` Berlin '' as a whole , but a separate place .
