It's more to make sure I know which '37 I'm moving as I have several running at the same time on my mainline and in and out of my fiddle yard, as I have, on more than one occasion collided into my rolling stock causing derailment's when I thought I was moving one loco but wasn't, I really have to re number the loco's but having recently inherited over 60 various diesel and steam loco's that need servicing, cleaning, repairing etc. it's a ongoing process
