    The speed in Automatic is no faster than it was as trains are still governed by the automatic blocks and timers of yore.  The difference is that the signals are quickly cycled electronically, based on the data it receives, and not mechanically (or pneumatically).  This substantially cuts the distance between consists and permits closer, yet fluid, headways.  That's how service can be increased, assuming you have the equipment, crews and budget to do it.  In short, CBTC does not promise FASTER trains, but should support MORE trains, which can keep moving along and not create traffic jams.

    A certain T/O I know would like to disagree with you on this statement. Final build-out of the signalling system for Flushing CBTC involves removing a TON of existing signalling, ie, lengthening blocks; certain speed restrictions will be (and some have already been) lifted.

    I think it more about an NTT on the (A) more than anything else... If the ten car R179 debuted on the (Q) for example, I doubt people would care as much.

    Well, let's be realistic. There're people who'd still foam over that.

    24 5 car sets, or roughly 120 individual cars,

    for reference, the (A) has a bit above 300 individual cars in service. So R179s definitely are enough to cover a vast majority of the (A) fleet

    No, the (A) runs 38-39 trains during the peak hours. That is the equivalent of 380-390 60-foot cars. 

    12 trains is not a "vast majority" of 38 trains, nor is it even "roughly half", and that's before you even consider the fact that at least 2 of the 12 trains will be out of service at any given time as part of the spare factor.

    Then I suppose 3112-3113 will be coming tomorrow?  That would be weird considering it's usually been the highest numbers first.

    Unless they came in yesterday.

    So far, this is my list of delivered cars. Am I missing anything? I haven't really been paying attention too closely.

    3010-3019 (10)
    3050-3069 (20)
    3078-3101 (24)
    3110-3113 [4]

    Saw both R179s passing each other this morning at Kosciuszko Street, thing of beauty. Though we all got discharged at Lorimer Street just minutes later due to a mechanical failure. Fun morning.

    I did notice that the LCD is quite low-res. I wonder if it is the panel itself or the actual image fed to it.

    The LCD screen on the 179 FINDs is larger than the 160 FINDs, but the TA never re-did the image resolutions for the 179 display, hence the blurriness.

    But why was it added?  I vaguely remember a few years ago when the (Q) used to fly into that station, so I'm guessing that timer is only a few years old (unless I never noticed).

    I think there's also one southbound approaching Prospect Park; it's either a timer or it's due to the steep gradient of that stretch of tunnel, because trains slow down well before entering the station.

    Signal department has been adding timers left and right over the last decade, all in the name of safety......

    Yes, there's a timed section coming S/B into Prospect Park because of the blind curve just before the station. Once you clear the last timer, you're in the curve and starting to go uphill.

    I've never really noticed the (Q) unnecessarily slowing down before entering Kings Highway; is it a timer that allows for decent speeds?

    That timer is there to protect the reverse curve coming into the station; without it, you'd be able to fly in around 35 - 40 mph, which is not exactly desirable in that specific setting.

    True, but there are those awesome rare occasions where they don't slow down at all and you go reallly fast.

    In regards to CPW express northbound, the trick to have the timers clear perfectly is to keep it on the post until you crest the hill around 86th, then shut off power and coast down the hill. If you max out at 42 MPH at the bottom of the hill between 103 and 110, you don't have to brake for any of the timers until you hit the slower timers at the north end of 116th street.

    That's interesting - I've always felt the (L) moves much faster between short distances than any other line. That explains it.

    Btw does anyone know where, as of right now, trains go fastest? I "feel" like it's the (L) in the 14th street Tube, but inside a tunnel isn't a good measure of speed. There's also that 'dip' on CPW between 103rd and 110th, where the (A) and (D) go noticeably fast.

    The 60th Street Tube [ (N)(R)(W) ] is still the fastest section in the system. If the timers are run correctly, you can still do 60+ MPH in that tunnel. I've heard 64-67 mph on a 160 Siemens; most of the acceleration above 55 mph would be gravity anyway.

    He sure had somewhere to go!! Think he got the call from home :lol: lol.. Yeah seem like in the 50mph range. I stumbled on a video not so long ago on youtube showing an R160 coming into 42nd on the express. Similar that unit had a gravity assist of course as well. Yeah, 86 to 42 sb had to be fast.

    The R142 train in that video takes about 7.5 seconds to pass by the fixed point (which is the nearest station column). With 510 feet of train, that translates to about 46 MPH.
