The Railway Goods Van

This old railway goods van sits at the back of the barn and is in need of some TLC, so today we decided to put some new roofing felt on in an attempt to stop some of the rain from coming in.
But once we had taken all the old felt of, it became very apparent that the goods van was past the TLC stage. The sides have come away from the floor, and the floor, which has been patched in several places, that when Holly walked on bounced. Not good.
So we have decided to condemn it. Trouble is, it was a good place to store all the slab wood that needs cutting for our log burning stoves. Which means that all of it will have to be removed and a new, dry home found for it all. Tim had already brought a trailer load into the barn for me to start chopping and whilst we unloaded it this afternoon, we did a very ruthless sort out of what was good to burn and what was not.
Tomorrows job, you've guessed it. Remove the rest of the wood from the goods van and then decide how we are going to dismantle the van, without damaging the barn behind it!!!!!! Any suggestions..............
