"When there was only one line for the whole of London" What can that
refer to? Neither telephones nor rail lines makes much sense in this

When the various "lines" that now form the London Underground were
built, they were separate railways and were referred to by their
names, ie C&SLR etc. I assume that the practice of calling them lines
must have come in when they were all part of London Underground. Does
anybody know when the term "line" first came into use in this context
