Hi PJW:


thanks for your explanantion. I have looked the past post. but i still don't understand (i think i only have a general idea,but i would like to know more in detail), can you explain more in detail ? or do you know where i can get more information from ? (books ??)

thanks
william

The former Railway Group Standard has some information about what aspect sequences mean and, in its explanation of what should be shown, has some diagrams which support the words.
