Last year Eye brought us pictures of a tree on a bridge at Ambergate, resolutely withstanding any lumberjacks who may be patrolling the MML.
As the 2009 season of mists & mellow fruitfulness draws nigh, I popped up to see how the "garden" is getting on.
As you can see, the tree has had a little light "trackside" pruning - nothing too severe.

Perhaps Network Rail are leaving them there so they can act as carbon neutral stanchions when the MML is electrified?
