Indeed. The Tories are currently doing the exact same thing, but because they are Tories, no-one likes the idea, and shouts "privitisation". Hopefully Labour, because it's Labour, will be able to make some meaningful changes, because, you know, it's OK, because they aren't Tories but Labour.
And you could say that about most policies to be frank. Labour will pretty much do the same as the Tories, but it will be more palatable, because people are ready for a change, any change.
To the OP - No "real" lefty parties have won elections for decades, Labour has to be centre left to get elected aka "New Labour", hence the need to distance themselves from the "loony left".
