Derailed fixed truck artics.
  Dudley Horscroft

I think I have now caught up with the emails regarding re-railing fixed
truck artics.  No doubt someone managed to do the job, else there would
have been more emails about it.  However, I can only think that the best
way to do the job would be what you do with toy trains, pick it up and
put it back on the tracks.

Two cranes, one for each half or just a large side loading fork lift, as
used to load containers on some ships.

Obviously in the past, derailments have not been too bad a problem, but 
might it be that with cement lorries and fire trucks rampant on the
roads, stronger measures are needed?
