A lot (well, I haven't found any that are not like this) of the railway near me
(Leicestershire, UK) has four nodes where there should only be one. Of course,
only one of these nodes is actually used.

They all have low ID numbers, so must have been around for a while. I've sorted
one or two, but it's a real pain to do manually so they usually get left. Ideal
project for a computer to look at ;).
