VIDEO: Dapol semaphore signals

In this brief video we highlight the operation of Dapol's new GWR lower quadrant signals for 'O' gauge - the same mechanism is used in its new design of GWR bracket signals for 'OO' gauge. The signals are servo operated and can be DC or DCC operated. This signal is controlled by Train-Tech's new SC4 signal accessory decoder which is has been created specifically to work with these new items.
