At least I managed to recover all the bits from the gravel. At one point, when back at the workbench, I wasn't quite sure that the jigsaw was complete, but after a bit of puzzling, it is.
Assembly of this kits was with Revell Contacta, which sticks the ABS material, but weakly enough that the joints break cleanly. This makes reassembly a lot easier. The clean breaks extend to the paint, which won't need a touch up either.
Half an hours work, and everything is as good as new. I've used Contacta again, with the odd wash of ABS solvent to speed up the joint drying.
The thing is, I really liked the look of the train behind Ragleth. Which is why there is a box with some more of these kits in the office now...
