There are other features of course, but these are intended to be easy to spot even if you don't have other locomotives in the same photo to compare with. The King has the largest boiler, the County boiler is notably short and stumpy, the Star, Saint, Halls and Grange all have the same boiler, and the Manor the smallest boiler.

And here are some profiles so you can work out which is which (and if you want to cheat the class is on the name plate)
