Can anyone here with documentation explain the reason LIRR chose to go with the Numeric cab signal indications and not the position light aspect as the PRR has done when first installed?
Older LI CSI units had a (MAS) (30) (15) or a (12) 3 aspect indicator
Where as the PRR units and the aspects actually displayed and not the signals speed.
(Clear) (MAS)
(Approach Medium) (60*)
(Approach) (30*)
(Restricting) (15/20) for slow speed aspects and restricting.
* not sure what speed the PRR associated with their signal aspects.
Thanks for you help.
