:::::Okay, one last time: with streetcar systems, grade separation is the exception.  For light rail systems, it is the rule.  For streetcar systems, multi-car trainsets are very much the exception.  For light rail systems, it is the rule.  For streetcar systems, wide regional applications are the exception.  For lightrail systems, it is the rule.  For streetcar systems, high speeds (25mph +) are as a rule not acheivable or desirable, because they run on low-speed streets.  For light rail systems, high speeds are desired and acheived wherever possible.  For streetcar systems, vehicles generally carry fewer than 100 people.  For light rail systems, trainsets generally carry more than 400 people.  Streetcars generally resemble what have been called "streetcars" since the 19th century.  "Light rail" generally resembles what has been called "light rail" since the 1970s.  I could go on and on and on, but I already have.  Why can you not perceive the difference between these things?  00:10, 22 Apr 2005 (UTC)
