Now, compare this with Virgin West Coast from here in Euston to
Manchester. The journey time is very similar at 2h40m but
obviously the distance covered is far less than above.

Well, it's about 18% less.

* New York Penn station to Washington - 225 miles - 82 mph
average
* Manchester Piccadilly to London Euston - 184 miles - 69 mph
average

Anyone have the mileage for London King's X - York? That is one
quick ride - the 1500 does it in 1 hour 45.

188.4 miles, which gives an average speed of more than 107 mph.
