No merge with the regular L line page please. If anything this article on subway automation will gradually be expanded as the CBTC system is installed on more subway lines in New York and the tie in to the L line will be diminished. At that point it won't make sense to have in as L line page, so why move it there now? It's a distinct enough subject to remain seperated form the regular L line page. —The preceding unsigned comment was added by Rock nj ( talk • contribs) .
The result of the move request was: page moved. Propaniac ( talk) 17:37, 20 May 2010 (UTC)
BMT Canarsie Line automation → Automation of the New York City Subway — With this article being expanded to include the automation of the IRT Flushing Line, it is no longer at the right title. I propose we move this article. Acps110 ( talk • contribs) 17:55, 12 May 2010 (UTC)
The article seems biased toward CBTC. Perhaps references to differing opinions are in order, eh? 98.113.229.245 ( talk) 02:34, 13 June 2010 (UTC)
Well, since my removal of this material was reverted, time to discuss this. I removed it for three reasons. First, it's completely unreferenced, so there's no real way to verify if it's accurate. Secondly, because this material is too detailed for an encyclopedia article, being essentially straight from an operators manual.
Thirdly, it's not really that relevant; it doesn't describe anything about the planned system, nor anyting about its implementation, which is the focus of the article. It is sufficient to say that the current system is a version of automatic wayside signals, as the article already does, and link to an appropriate article, as again, it already does. Maybe if there were an article on current sgnalling of the subway, these charts woud bring there, but that is it here. And again, it's completely unsourced. oknazevad ( talk) 18:46, 9 October 2013 (UTC)

Automation of the New York City Subway → Signaling of the New York City Subway – I suggest this for the following reasons:
1. This page includes a substantial amount of information about the old wayside block signaling system in place throughout most of the system.
2. The rest of this page is about CBTC, and CBTC is not simply automation- it is a new signaling system which enables partial automation. CBTC in the MTA's current and planned installations still requires operating personnel onboard the trains.
3. There is no page for NYCS Signals, which is certainly a broader and more notable subject than an "automation" which is not really happening. Furthermore, such is the topic that this page is currently describing, despite its title. 2604:2000:C6AC:D00:31E8:786D:9719:6806 ( talk) 16:46, 6 August 2015 (UTC)
The main article says 28 tph, this says 26. Is the 26 the actual and 28 the possible? Lex line already runs close to 30 and that hasn't been updated yet, headways are as low as two minutes though that may be due to rounding error. CBCT and other ATO-related articles, including individual metro aritcles, don't give enough info let alone in a concise manner such as more mention of actual service headways, not just tph. I've heard of headways on a heavy metro as low as 105 seconds, and possibly even 1.5 minutes, 90 seconds, but I think train length and also dwell time is the limiting factor on NYC subway.

I'm not the only person who has taken pics of one of these, but I spotted this signal at Hunters Point Avenue (IRT Flushing Line) back in November. I hope I'm not wrong in assuming this is a countdown clock, like on pedestrian signals. --------- User:DanTD ( talk) 16:01, 30 December 2017 (UTC)
@ Epicgenius: I feel as though that this section will become bloated and too large, with too much of a focus on recent events, if it hasn't already. Maybe it could be cut back here and moved to 2017 New York City transit crisis? Thanks.-- Kew Gardens 613 ( talk) 22:47, 21 January 2019 (UTC)
@ Epicgenius:, how would you recommend adding information concerning the CBTC Equipment Supplier Interoperability project and the Ultra-Wideband pilots on the Flushing and Canarsie Lines? Thanks.-- Kew Gardens 613 ( talk) 23:25, 23 June 2019 (UTC)
In UK get lots of signal failures. Track Circuits fail often. If 2 Track Circuits are connected together with a pair of wires, create a false feed, signal will show clear aspect, train will rear end another one. Ian C Burnett ( talk) 14:20, 13 September 2019 (UTC)
@ Kew Gardens 613, I found this source when looking for something unrelated:
This source has a bunch of info about the original signaling system of the IND, such as details about grade-time signals, bidirectional signaling on the central track of the Concourse Line, and signal towers. There might also be another article about the Eighth Avenue Line's signaling in the October 1932 article of the same magazine, though I haven't looked into it yet. – Epicgenius ( talk) 22:32, 7 May 2023 (UTC)
