Affected stock: BR Class 375 from SHS. Issue: When connecting a keyboard, the R and F keys can be used to adjust the speed limiter, the same as any other loco including such a feature. However, the 375 doesn't actually have a speed limiter. Pressing these keys therefore adjusts the dial next to the anti-icing button and doesn't actually do anything. It would seem this feature has been left in in error, presumably as the 375 is based off the 377 which did include a speed limit function.
