Would it be true to say that the flashing red 20A signal is permissive signal of some kind while the steady red 20B signal is an absolute signal. Otherwise what is the principal difference?

- Both are absolute. 20A is used for entry to a station and in block posts (points on the line that seperate two blocks), while 20B is used for exit from stations.

[edit] Home and Distant?
How does one combine a home signal and a distant signal on the same post?
Tabletop 11:37, 19 May 2005 (UTC)
- The distant signal is placed on the same pole, below the home signal. Usally, the distant and home signals are to separate units, but they can also be combined in a 5-aspect unit (green, red, green, yellow, green). The distant signal is not lit when the home signal shows signal 20A.

[edit] Flashing Ink?
How does one arrange things so that the flashing (pulsating) colours on the article page of this topic continues to flash when printed out on paper?
Similarly, how can the coloured signals still be recognisable on a black and white printer?
The flashing signals all appear black on the printout - oh dear!
