I was led to believe that the point of the loop would be that you

about the trains themselves!), the economics didn't add up. More
juice, heavier, higher leasing...can't say I remember or indeed ever
knew the details.


If the economics of a loop and new rolling stick "don't add up", let's
see you try to justify the cost of constructing a flyover/flyunder,
which would be orders of magnitude higher!

Should be quite a laugh.
