There were some issues with the mounting of the stem on the titanium fork of the Brompton Superlight that could make the fork tube crack but its not a real design default, crack happens only when the stem mounting is tightened too much what could easily happen if the tightening wasn't done with to torque wrench. Brompton modified the mounting of the stem using a classic quill mounting.
About the hinge, you can easily see the difference of the hinge of the T-line and G-line on the pictures below:
The fix of the G-line seems to be a reinforced spindle.
I don't know which is which, but the gray bike (T-line?), note opposite side of the pin, there's a small vertically oriented protrusion and mating slot for it inside the hinge, and notice that it's tapered for a tight lockup; That may do a better job of keeping the hinge halves aligned under frame torsion (climbing while standing is worst), and thus reducing loads into the pin. It does nothing for vertical bending loads on the pin. Since the pin interface is hard-steel pin on steel or titanium frame, it would be nice if there were replaceable metal bushings on which the pin bears, but I doubt it. Lacking that, I'd fab a kevlar/amsteel diagonal line to Triangulate-Tech^3* (tm) the frame and reduce bending loads on the pin.
