Why New York Subway Lines Are Missing Countdown Clocks

The meat of the story is that the MTA purposefully allows their system to remain crippled to drum up public money.<p>&gt; That’s why the MTA has tried to associate CBTC [a enormous overhaul of the signal system for the subway] with countdown clocks. New York riders crave realtime information about trains. They don’t care how they get it. So when Transit wants to drum up support for an obscure, costly, many-decades-long capital project to upgrade to CBTC, they always point to the clocks. (“Sustained Investment Makes Real-Time Information Possible,” declares one 2012 press release.) Reporters, struggling to make sense of a half-dozen interrelated projects, follow the MTA’s lead and assume that realtime train-location information depends on signal upgrades.<p>&gt; But that would make for some pretty expensive clocks, and it would make them awfully long in arriving. The F train, for instance, if it had to wait for CBTC to get realtime arrival information, wouldn’t see it until 2035.<p>&gt;It’s a misleading narrative. You can get countdown clocks without touching the signals. The MTA knows this.<p>The analolgy with the ACA website comes at the end:<p>&gt; I keep thinking of Healthcare.gov. Everyone knows that the initial project was a costly disaster, but less well known is that a small team came along and saved it. The story includes this remarkable fact: The old system cost $250 million to build and $70 million a year to maintain. The new system—which actually worked—cost about $4 million to build; its yearly maintenance was about $1 million.

It&#x27;s worth pointing out that the Bernard S. Greenberg mentioned in the article in connection with NXSYS is the celebrated Multician who ported Emacs.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Bernard_Greenberg" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Bernard_Greenberg</a>

Well, if all they&#x27;re after is a system to inform the ops where a train is... put active microwave beacons on the train ends, and recievers in regular distances in the tunnels. Problem solved.

By way of contrast - not only does the London underground have countdown clocks on platforms (accuracy +&#x2F;- 1 minute), they also have an API allowing 3rd party developers to integrate tube (and bus) times into transport apps.<p><a href="https:&#x2F;&#x2F;tfl.gov.uk&#x2F;info-for&#x2F;open-data-users&#x2F;" rel="nofollow">https:&#x2F;&#x2F;tfl.gov.uk&#x2F;info-for&#x2F;open-data-users&#x2F;</a>

In Russian metro there are count-up timers. Not that this is a big deal, though, when intervals between trains are shorter (2-4 minutes in St.-Petersburg; less in Moscow).

CBTC and moving-block signalling systems like ETCS are nothing new though? They have been in use on main line railroads and subways all over the world for years now.

I&#x27;ll take the New York Subway system any day over what Boston has (MBTA).
