I tripped myself.  The term "Medium Clear" should be "Clear Medium"
in DL&W and EL terminology.  Most other railroads, including my NYC
and D&H, used "Medium Clear."  EL had a good reason for being
different, though.  When signal indications are exchanged across
the engine cab by name, (Rule 34), it is less likely that "Clear Medium"
would be misunderstood as "Clear" than would "Medium Clear."
Sometimes only the last word makes it across in noisy conditions.

No.  If the westward signal from the Greenwood Lake to Boonton at Mountain
View displayed an aspect indicating "Clear" it would be Green/Red/Red, and
a "Clear Medium" would be Red/Green/Red.  Which one was used depends
on whether or not EL counted on the timetable speed restriction to enforce
the 30 mph limit. Either one would only be true if East Lincoln Park was 
lined
for the main and cleared (either "Clear" or "Approach").  If East 
Lincoln Park
was lined for the siding, under EL rules, the best you could get at Mountain
View would be "Approach Medium," Yellow/Green/Red, if Mountain View
 was signaled as as straight route, or "Medium Approach" if Mountain View
was signaled as a diverging route.
