I think the biggest failure of the APT was not so much the technical glitches associated with the new technology even though they resulted in much bad press publicity which admittedly certainly didn't help matters. The end of the project I always thought was brought about by the bigger issue of the Kinematic Envelope being flawed in relation to the infrastructure.
Or, simply put, the damned thing was "too big for our railways" which created clearance and safety issues due to its ability to tilt. I believe that one of these issues was that two APTs with failed tilt mechanisms stuck so as to lean towards each other could collide when passing. This kinematic envelope may also have had consequences for the general network of platform edges, tunnels etc etc.
