Basically unit is robbed of every useful part that they can get away with for spares.
I think, more accurately, it's stripped of those things for which the TOC is responsible, rather than the ROSCo, and for which the TOC has further use. I can't think of specifics on these units, but were it a bus, it would be stuff like ticket machine, cash vault, GPS equipment and so on. If the TOC has installed FFCCTV or other systems in its own right, these will be removed if they have reuse value. The other aspect of decommissioning will be draining any fluids etc. that aren't required for the unit to be dragged.
