I went to my local model shop to collect my dcr class 31452 and whilst we were testing it , I noticed Hornby have changed the light configuration and now its wrong the issue is as follows   when going forward the red tail lights light up white along with the headcode and hi density light and other end just the red tail lights and change direction and same again, its not right   We then tried a network rail one and same issue,  Has anyone else noticed this change in the class 31s and why chan
