These are not quite the same thing, being effectively permissive block signals on goods only lines.

 

No , was TCB you got a sub if going behind another train

Only colour light signals capable of displaying a stop aspects are fitted with telephones, there's no point providing on a telephone on a distant signal which you never stop at (of course unless choose to or the train fails at it).

P.S. Just for a shameless plug, further detail to all my above posts can be found in my book 

 

Between Norwich and Haughley the distants have phones this was because the signals are quite far apart (two aspects)  and it was so if you needed to find a phone you were never more than two miles from one

An example of a main line with alternate Y/G and R/G signals was Stage 1 of Oxford Resignalling between Wolvercot Junction and Aynho Junction in 1968.

A dimensioned plan was included in the traffic notice available at https://www.signallingnotices.org.uk/scans/35/1968 - LXO 102 Oxford Stage 1.pdf
