Hello all,

The latest round of questions into signaling and position lights got me
wondering about some things. Living up here in New Jersey, I'm familiar
with PRR position lights and their use of say "Medium Clear". Where as the
N&W used and NS (Outside of former CR territory) still uses "Diverging
Clear" on position lights. Was this something that was done at the
beginning of the use of position lights on the N&W or was there a time
where they to were using "Medium" as well? Seeing as how the PRR had
influence over the N&W I've always wondered why the signal rules were a bit
