Train horns/whistles broken – Tiny Rails Review

I have been Messing around with locomotive and I have come across something weird, the blue ducky A4 (or the Mallard) is a diesel horn. The yellow diesel has a steam whistle. Please fix this and make me happy. And please tell me what engine the 844 is. Or add one if it is not in the game!
