[edit] No fishtail UQ

There have never been fishtail UQ distant signals. (pointing inwards).

There have been pointed automatic signals between Hexham and Metford (pointing outwards). These signals showed stop, caution and clear.

Tabletop 02:03, 5 February 2006 (UTC) I know that there have not been fishtail UQ signals. I don't know why I wrote it and I couldn't believe I wrote it, but whenI saw it I corrected it. I suppose we can all make mistakes.

[edit] Queensland Signalling

QLD signalling (aka QR) is not 100% as per UK practice. There are some notable differences. One of them is the Flashing Yellow. In UK it's to advise the driver that the next signal is set for the junction. In QR, it is used as a Warner and advises the driver that the route is clear to the next signal with little or no overlap. The Double Flashing Yellow is not used in QR. However in QR, a Dynamic Speed Indicator (DSI) has been created, which is placed on the signal behind the junction signal, to advise the driver what speed to do through the junction.
