I don't want to get off topic here, but Quantitate Easing is far more complicated than just 'printing money'. Sure, governments can and do 'print money', generally to keep track with natural inflation and ensure the money supply in an economy remains viable. Printing money to get yourself out of debt or in any large quantity is stupid and causes inflation, often hyper-inflation.
Regarding borrowing: The UK's credit rating is now AA (down from AA+, which was down from AAA, mostly due to the B-word), with our gov debt something like 88% of GDP - that's high, probably a little too high, but it's not as high as France, the US (105%) or Japan (200%). Bear in mind last time I looked at this was about 2 years ago so figures might need updating. Crucially, there's confidence in the UK as an economy (less than 2 years ago mind) that means that creditors are still willing to lend us money - what helps is our governments fiscal policies and their 'commitment' to tackling deficit. A government that doesn't 'care' about debt is going to have less confidence in it by lenders. The UK can borrow money for HS2, HS3, third runway....really whatever it likes.
THAT BEING said: THIS DOES NOT MEAN IT SHOULD. There's a whole variety of reasons why, most of them not to do with borrowing at all.
With regards to EWR, I'm most disappointed by its demotion as an electric railway, rather than the removal of freight loops.
