Seeing how these old signals are quickly on their way out, I wanted to make sure I got a shot of them before they inevitably disappear. In the pre-UP era, that lower target on the signal on the right would display a lunar aspect, indicating a grade (restricting) signal. Today, the yellow G-Plate has been added (indicating a grade signal), and the lower target displays yellow, for a yellow-over-yellow aspect, if a train is going in the hole at Leyden (Approach Diverging).
