- Unfortunately I don't agree. There are no mainline flashing yellow signal
- indications. What you refer to is still a pulsating signal. I was a
- trainee signal engineer for four years, so I should know.
-
- Now being an acting driver (ie. locos), I should know even better!
-
- The new interlocking at Maitland came after the initial installation at
- Berowra. In fact, the success of the one at Berowra was the reason this
- has been adopted elsewhere. The south coast is full of signals that show
- this indication.
-
- You have to be clear on the definitions. And is apparent that some other
- systems (mainly overseas) use 'flashing' to refer to lights that actually
- pulsate (ie. they just alter the intensity, but don't turn off during the
- duty cycle), and vice versa. The NSW definitions are literal.
