Piggy trains

Hi guys, could you explain to me how they work?

It's where people get s piggy from one place to another. For example say someone saw some piggys in a rescue in Birmingham they wanted but they lived up north, I would collect them as that's near me, I may look after them for a day or several, then drive them to another location to another member and then they may do the same and so on until they reach then destination
