Deletion of BR Class 37 renumbering

Comment: The deletion rationale is poor, but speaking as a railfan, this is the prime example of the sort of content we should discourage rather than encourage. It's not encyclopedic. It's sourced, in the sense that it was copied out of Ian Allen railfan publications (I own several myself). That the class was renumbered may be worth mentioning and would be a good example of |summarizing content; listing each and every renumbering would be better done on an external site
