Over time I have forgotten how Graham and I were

invited into the huge Chetser No. 4 signal box. However, to prove that we were here is a photograph of the interior looking along the length of the impressive one hundred and seventy-six lever frame. By this stage of its operating life with just three years left in use, there are many levers painted white and out of use. One of the two signalmen on duty looks like he has just pulled off a blue lever that would control some sort of ground frame. I am not at all sure what the green tape wrapped around the handles of some of the levers was for.
