LIRR does not use a cab-proceed signal like some other railroads. LIRR's most favorable signal is clear.

Head-end View wrote:LIRR also has a color signal called clear block (green-over-green). I'm not sure what it's used for; possibly a proceed indication at the end of signalled territory. Maybe some employees on here could help us with that one.There wouldn't be a signal at the end of ...signaled territory. From discussions (ad nausea) on this forum, LIRR does not consider Manual Block Territory to be non-signaled territory. The Book of Rules backs this up, it defines both Manual Block and Automatic Block as signal systems made up of consecutive blocks - absence of track circuits notwithstanding. From what I understand, at the end of a signaled block entering a secondary track, there could be a Rule 296 fig.B "END OF BLOCK" sign. This was the case when the Rule 251 ABS signaling ended at Bliss, at the entrance to "C" secondary. (Before they invented the NYAR Secondary)
Head-end View wrote:The green-over-green for clear-block is new since 2006 when LIRR first began color-light signals at Patchogue. Green-over-red-over-red would be a clear on most railroads.Thanks, Head-end, I was wondering as I wrote that last post how the Clear Block was displayed at SK2 in Speonk before the CTC was complete from there to Montauk.
