HS2 would have removed high speed trains off the main lines to allow for more regional trains and/or freight trains.  Only after it began to be cut back did its goals become rather pointless and now we're at a point where it looks like it'll run on exisiting lines designed for tilting trains without using tilting trains - so they'll have to run them slower.
HS2 as a concept is a great idea - right up until the idiots in charge decided to meddle with it.
