G-20 leaders need to forcefully address the complications created by this bifurcation of growth prospects and required policies. Otherwise, we are in for a train wreck.

My comments:

In other words, great damages will be done.

A train wreck happens after the train goes off rail….

You see the picture, of course. In other words, all that is left is the wreckage. Likewise, a car wreck or ship wreck also refers to great damages done, to the car or ship after, say, an accident.

In the G20 example, "we are in for a train wreck" means that if the G20 leaders don’t get their act together and come up with policies that will actually work, the world economy will, again, be heading towards a crash.
