A different rule book that doesn't apply, but NS signals define a green dwarf as SLOW CLEAR, which is 15 MPH until clear of the interlocking. Not the "I brake for animals" speed of restricting (which includes being able to stop within half of the length of vision for defects, etc) but a signal that says the track is clear until the next signal.

The N&W started colorizing their Position Light signals in 1959.They started colorizing the dwarfs in September of 1964, according to Eric on his website for N&W CPL signals (which apparently is no longer around). Rules 287 and 288 - In the bottom position of the 2 aspect dwarf color light dwarf signal. Rule 290 - In the upper position of the 2 aspect dwarf color light signal. Rule 292 - Stop in all three dwarf signals: semaphore and 1 and 2 aspect color light. Rule 293 - Siding derail target, in derail position. A block signal with triangular plate bearing letter P is also actuated by a special protective device(s).

Dwarf signal aspects

Three position signals always need two arms or lights to display their aspects (except in the case of dwarf signals) and in Victoria a total of 6 aspects can be displayed by the combination of the two lights (7 if low speed aspects are included) http://www.ebay.com/itm/252440296081?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIThttp://www.ebay.com/itm/400943354498?_trksid=p2060353.m2749.l2 https://www.youtube.com/watch?v=X_E02 Dwarf Lights. http://www.ebay.com/itm/10-sets-Targe Loading Autoplay.

A 2-color dwarf signal often is used to indicate the position of a turnout. They take on quite a variety of forms -- vertical, position light or searchlight. In addition to Rule 9.1 of the General Code of Operating Rules, the following General Signal Instructions apply on BNSF Railway: • Dwarf signals will display the same aspects and indications as high signals. • The following symbols are used in diagrams of signal aspects.

However the cost effective signaling award might just belong to Conrail for its use of virtual headed 2, 3 and 4 lamp dwarf signals. Now this might be more widespread and I'm probably being a bit unfair picking on Conrail, but on the other hand the NORAC signal aspect system was tweaked specifically for just this sort of low cost signaling so I suspect that Conrail was one of the more
