For the sake of consistency with proper terms, I'd recommend changing bogie related parts to have "Bogie" instead of "Bogey in the part names. Now, this does have the issue of potentially breaking pre-existing models but allowing both "Bogie" and "Bogey to be used for the same purpose would avoid this issue, whilst allowing people to have their preference on which they use. Some valve gear components already have this feature, so I imagine this wouldn't be too hard to implement.

Could be added as an alternate name in the regex
