wil9402 Posted January 22, 2012 Report Posted January 22, 2012 Passengers? The most blatant example I've seen of this recently, with the person running down the stairs and actually bouncing physically off the door that had just closed, was an off-duty TTC operator! They're still passenger, are they not?

smallspy Posted January 23, 2012 Report Posted January 23, 2012 The entire braking system is controlled by computer, which has a software the controlls it. I'm sure that with some fine tune'ing that you would be able to find a sweet spot and prevent the wheels from locking up....at least in Theory. You think that if it wasn't possible to do it that they wouldn't have by now? The cars have anti-slide systems. But sometimes even computers can't react fast enough to physics. By the way, when it comes to steel-on-steel the moment of most grip is when the tread of the wheel is travelling at a very slightly different speed than the rail. It is called wheel creep and equipment with traction control has been set up like this since the 1980s. Dan
Shaun Posted January 23, 2012 Report Posted January 23, 2012 So you are saying flat wheel spots are a factor of life and you have to live with it?
Turtle Posted January 23, 2012 Report Posted January 23, 2012 The cars have anti-slide systems. But sometimes even computers can't react fast enough to physics. On the ep brakes too, or just the dynamics? So you are saying flat wheel spots are a factor of life and you have to live with it? No, just smack the ops upside the head when they make flats.
smallspy Posted January 23, 2012 Report Posted January 23, 2012 On the ep brakes too, or just the dynamics? The older cars had it on both, so it stands to reason that the same would apply with the TRs. Mind you, the rail has to be in pretty shitty condition before you start to cause it to slip in dynamics.

nfitz Posted January 23, 2012 Report Posted January 23, 2012 Bouncing? We were only a door away from the conductor. I have to wonder if they closed the door deliberately, knowing the guy wasn't going to be able to stop ... The bounced operator did look a bit taken aback when the doors started to close ... It was quite entertaining.

Edit/Add: You can hear the dynamics changing "tone" in the (T1/H5) car with the spin/slide, but never put 2+2 together on that. It's not something they teach the operators, they don't really go into technical details of the trains. As far as slide goes, it's more along the lines of preventing flats and overshoots by applying less brakes sooner.
TDE Posted January 25, 2012 Report Posted January 25, 2012 541x Tuesday and 5501 this morning were at Davisville Yard. First time I've encountered them sitting that yard 'as per usual'.

TTCNLFBT Posted January 26, 2012 Report Posted January 26, 2012 A lonely TR 5523 is parked at Wilson.
BBfellow Posted February 1, 2012 Report Posted February 1, 2012 551x is in service. Rode on it today. Didn't even have to purposely wait for it, it just came. Also, there seems to be less 'bugs' with the doors now.
eja2k Posted February 1, 2012 Report Posted February 1, 2012 Also, there seems to be like 'bugs' with the doors now. ... the doors have always had 'bugs' ...
BBfellow Posted February 1, 2012 Report Posted February 1, 2012 ... the doors have always had 'bugs' ... Ooops, sorry! Meant "less bugs"... fixed it!
Articulated Posted February 1, 2012 Report Posted February 1, 2012 There's a potentially serious quirk with the TR's door closing sequence. Because the door closing chimes and warnings play out over the internal PA system, whenever Transit Control is making an announcement inside the trains, the door closing chimes and warning is not played, and the doors close silently with only the flashing light to warn people.
buschic Posted February 2, 2012 Report Posted February 2, 2012 The one thing I'd like see fixed if possible is the dammed gap, the height of train vs, platform gap, its driving me bananas, I've nearly tripped so many time in the last few weeks, that I'm gutting nervous just wanting to get on the TR's, I've had to modify the way I probe with my cane before getting o with them, its annoying because it slows me down, & people tend to push you when your in a crowd trying to get on during rush hour.. which can be really dangerous.

Thankfully, the TRs doors are over-sensitive. They re-cycle even if there was a strong wind gust from the other side of the platform.

I rode 551X today, the announcements in 5511 seem a little off, almost like two speakers aren't synchronized properly. There was a 7 minute gap infront of it and the train behind it was only a couple minutes behind. Doors still seem a little buggy, took a while to open when getting off at Dundas. There's also a door that's out of service on 5511.

There's also a door that's out of service on 5511. That gap in front of it was because the train in front, 5401-06, was pulled from service southbound at Lawrence around 8:45am due to a mechanical problem. 5511-16 was at the end of a group of 5 TRs during AM peak.

People with motorized wheelchairs or scooters, especially the ones with small front wheels, have trouble with it too. The ttc have gotten the heights a little bit better, pretty close to the rest of the fleet in some cases. No platform is exactly the same height, especially when they start to sag like the east end of Union (Yonge side). I don't know what can be done to fix them, it's not for lack of trying. The ttc has a guy that goes out and measures heights on cars when there is a complaint or injury. One station manager does that sometimes too. Thankfully, the TRs doors are over-sensitive. They re-cycle even if there was a strong wind gust from the other side of the platform. Have you tried sticking your hand between them and letting them close on you? Now picture that hand is a dog's tail, a service dog no less who had a previous fracture from a set of doors.

I caught it southbound at Bloor at 11:13 though, which would've been on it's next southbound trip. More than enough time to recover.
Subwayboy Posted February 2, 2012 Report Posted February 2, 2012 Is it true that 5381-5386 Prototype Train 1, will be replaced by 6081-6086 5391-5396 Prototype Train 2, will be replaced by 6091-6096?
D. DeLarge Posted February 2, 2012 Report Posted February 2, 2012 Is it true that 5381-5386 Prototype Train 1, will be replaced by 6081-6086 5391-5396 Prototype Train 2, will be replaced by 6091-6096? Where'd you hear this? Doubt it. Unless there were some seriously unfixable flaws with both sets.
