So if the Amtrak diesels were converted to LIRR third rail then I must assume they run diesel even where MNRR third rail is present up the Hudson Line. Also, by Amtrak diesels you are referring to the P32AC-DM's?
Also if anyone has any insight on which tracks within the station have the third rail that would be appreciated.

When position lights were gradually introduced system-wide later on, the signals remained in place. In the brief glances I've had at them in recent years it appears that they have been replaced with new equipment, but displaying the original aspects.
Second question: They were installed in the North and East River Tunnels and in Penn Station itself because clearances did not permit semaphores, and while color-light signals of that day were not easily visible in bright sunlight, they were clearly visible in the tunnels. From what I can tell from photographs of the earliest days they used semaphores at all outdoor locations.
That makes sense. Those tunnels look way too cramped for any PL's or even full tri light signals. I would be interested in what aspects they can display whether they are that of a single headed signal or can display every aspect a double headed signal could display.
If anyone can dig up any pictures of these that would be most appreciated.
Thanks
