See, that would be amazing. As an ex (as if) train spotter I spent an inordinate amount of time with my head stuck in the annually published Combined Motive Power books. These books listed all Locomotives and electric/diesel multiple units in operation across the UK rail network. There is something about such taxonomic tomes, the layout, the systems of classification (don’t get me started on Dewey), just information presented in such a fashion gets me quite moist! But seriously, do it, I’d certainly love to work on such a project. Reference material *swoon*
