I think the class 37 itself is a really nice locomotive to have in the game and while the current noise isn’t bad it’s not amazing either. The idle sounds almost okay but I think acceleration noise needs reworking. It needs that fierce tractor growl in my opinion. Right now it sounds quite bland when accelerating, not much thrash and it’s lacking perfect noise. I think it would just be a nice idea to have a rework on the class 37 noise when accelerating and at speed. And on the topic of class 37s, I would like to suggest a ROG class 37 drag on the WCML south, perhaps starting at Wembley or from Milton Keynes to Wembley Yard? It would be a nice addition to the route to add a little bit more excitement. But I must say the WCML is my favourite route, great job on that one. Other than that I am very happy, but I would like a 37 sound rework. Thanks for reading and hopefully this will make its way into the game!
