That's okay, no problem.Sorry to add a "granny sucking eggs" type comment but it needs to be borne in mind that the brakes need to be unpinned from the same side that they were originally pinned down.
It looks like the person pinning down the breaks (hopefully) would know this and pin down the right hand side of the wagons. That way, unpinning along side the Up platform you would be free from the platform, in between both Up and Down tracks.
Thanks,
Andy.
