Just a small thing. The new static tube train at Earling Broadway on Great Western Express is clipping the buffers. Because of this if you sit in the seat of the cab it will immediately derail and end the service.
I know that there isn't really anywhere to drive it. I'm just saying that its what caused me to notice that it was clipping the buffers. I jumped into the cab because I was curious, and it immediately derailed. So I loaded back in to investigate a bit further and noticed the clipping.
