train with mechanical problems |

Posted by RAILFAN_7_40st on Wed Apr 23 10:18:08 2008 Due to a train with mechanical problems at the Northern Boulevard Station, Forest Hills-bound R and V trains are running express between the Queens Plaza Station and the Jackson Heights-Roosevelt Avenue Station.In addition, due to a train with mechanical problems at the Canal Street Station, Brooklyn Bridge-bound 6 trains are running express between the 14th Street-Union Square Station and the Brooklyn Bridge-City Hall Station. Please expect delays in service on the R,V and 6 train at this time. looks like that R32 need to be scrapped... & is rarely seen an r142 with mechanical problems |

The Victors Run R46's as well and they run on the Local Track just liek the Romeos which run R46's also.. & is rarely seen an r142 with mechanical problems I guess you havent rode the Subways a lot then i was in the A Div for 5 years got almost a book of R142's with mechanical problems in my head.. |

Jamaica yard doesnt take care of their trains so they brake down a lot. And the R32s do NOT need to be scrapped. Maybe the phase II with the braking probems yes but the phase I R32s HELL NO!!!! |

As was previously mentioned, the R/V would most likely be an R46.And if R142's didn't have problems, then why were these R62A's from the 1 line running on the 4…    …and 7?   And why were all these R142's seen in 207 Yard?

So if 1 R32 has a mechanical problem, the whole fleet must be scrapped? The 32s are the most reliable and cheap to fix trains in the system. Stop talking out of your ass. And BTW, the 142s are junk and are always breaking down. |

Bet the un-neutered redbirds would probably be better.Sometimes it seems as if the 62 are not as neutered as B division stock, because they seem to reach 30 miles a lot easier than ANY B div stock. |

I'd perfer to think in terms of maintain rather than fix. Fix, you do when it's broken but maintenance is more evenly balanced for all car classes. That being said, the 4 & 5 car links are less costly to maintain because;a) There are less components that can fail or that require maintenance. b) The inspection teams use less inspectors/car c) Since they are the newer cars the components are still more dependable and fail less frequently. d) Greater dependence on Solid State devices which have no determinate life-cycle whereas contactors, etc. do. |

Guy, they do that on purpose, they installed flaws into the contactors so that they fail more, that was a problem with the 68s when they first came.You can still have a smee with solid state electronics, you know. SMEE is the best design, period. |

Dude, I don't want you to take this the wrong way but I have no interest in your uninformed opinions. I've previously suggested that you shut your mouth and read more but you'd rather continue to pontificate, spewing your methane-laden rhetoric based on nothing but your own prejudices and 4th grade mentality. You are not well versed in the subject matter. You are not well educated in general and mostly, you are not even slightly likeable. I doubt that there are very few here who find your unsupported arguments even slightly persuasive. |

Do you not remember the problems 68s had with their contacts?You can have the SMEE design with solid state electronics too, you know. Replace the resistors with DC choppers, or inverters, and the hard switches with solid state soft ones. |

When they first came in, remember, they were considered to be lemons at first due to a JCDC switch, which would arc over, and cause a short, which would trip the breaker and cause dead cars. They fixed this by adding shock absorbers to the contact. |

Well as long as you are such a knowlegable train expert, let me correct a few things that you got wrong in your single mis-informed statement.1) It's J/BDC as in J switch/Build Down Contactor 2) It's not contacts it is a contactor 3) The J/BDC was unreliable moxtly because of two other devices that controlled it (The JMR and the FFR) 4) When the J/BDC failed, it did not close - it remained open - IT DID NOT SHORT 5) When the J/BDC failed, it did not trip a breaker and cause dead cars. 6) When the J/BDC failed, it did not close, allowing coast current to exceed design limits and resulted in overheated grids. So, let's see. You made one statement that had 6 glaring errors in it and still haven't idenified the the primary causes of the R-68s poor performance. Keep trying though. |

If you are interested in the specifics of the older equipment you'll probably have to get some old manuals or volunteer at a museum and get your hands dirty. If you want to learn about contemporary Railcar Electronics Technology, there is a school in NYC that offerss a good basic course. A few years ago I reviewed the course material and found it overly general if you want to know just NYCT equipment. It will, however, provide a fairly comprehensive overview of the field. |

I don't want to keep sounding like a moron when I type because I would love to learn about the older equipment (R32-R68). I will ask around the museum because I would like to work on this equipment, but before I do, I must learn from the posts from you, Jeff H, randyo, etc... I will also look into that school in NYC.So once again, thank you. |

Interesting.So the controller, which has 4 settings (coast and three increasing applications of power), was effectively rendered somewhat unresponsive to the engineer's command? The controller could be set to coast, but the current that was supposed to be registering whatever it was suppposed to - since I know little about such things, let's represent it by 0.25 A for coast and increasing currents above that in 0.25 A increments for each notch of power up to the full amp for full power - would instead register as a higher current, which indicated that more power was to be applied? |

To put it very simply, cars with dynamic braking never truly coast. When in coast position, the car is actually set up for dynamic brake but with enough resistance in the circuit to produce minimal retardation. The braking efort is then increased by stepping resistance out of the circuit.In the power modes, it's not as simple. (But to over-simplify) In the first & 2nd points of power the 4 traction motors ae connected in series - at first with maximum resistance. The resistance is stepped out, as the logic tries to maintain specific currents (by sending run signals to a motor that rotates a cam that steps out grid elements). In the 3rd point of power, the motors of the same truck remain in series but the two trucks are hooked up in parallel, doubling the effective voltage each motor sees. Other factors such as counter EMF and field shunting also come into play but would likely confuse things here. Suffice it to say that a train may begin in 3rd point at 475 amps (per leg) at start-up but will drop to less than 1/2 that once the train is up to speed. |

Can you explain what the fix involved, roughly speaking? |

For the curious, this is the story:Link April 5, 1987 SAFETY DEVICES FAIL IN NEW SUBWAY CARS By RICHARD LEVINE LEAD: Electrical controllers - sometimes called the brains of a subway car -have been failing on many of the two newest models in the city's fleet, according to Transit Authority officials. Electrical controllers - sometimes called the brains of a subway car -have been failing on many of the two newest models in the city's fleet, according to Transit Authority officials. Nevertheless, the authority has ordered 200 more cars with the same devices, which are made by the Westinghouse Electric Company. The controllers, which regulate acceleration and braking, can cause a car's motor to go dead when they fail. Although officials say they believe the problem can be solved, the authority has made provisions to have the controllers on the new cars replaced if the trouble persists. Each car has its own motor, and an eight-car train could run safely even if motors in two or three cars go dead. But authority officials fear that the strain of dragging cars with dead motors might damage the other cars, which cost $1 million each. The director of car equipment engineering for the authority, Frank D. Westfall Jr., said the controllers have malfunctioned on about 20 percent of the R-62A's, which began service in 1985, and ''at most'' about 10 percent of the R-68's, which entered service almost a year ago. The latest car equipment department status report showed that controller problems on both models increased in February. 'Towed Piece of Equipment' Officials say controllers made by General Electric, which are used on another model, the R-62's, have proven more reliable. However, the controllers made by G.E. are also $5,000 to $7,000 more expensive than the Westinghouse units, which cost about $50,000 to $60,000, according to Mr. Westfall. Besides price, authority officials said that they specified Westinghouse controllers for the newest cars, the R-68A's, because they wanted them to be compatible with earlier R-68's. Since the entire R-68 fleet is to be based at Coney Island, it will be more efficient to maintain the cars if they have identical equipment, they said. Mr. Westfall said the Westinghouse controllers, which are part of a car's propulsion system, started malfunctioning shortly after the R-62A's began arriving from their Canadian manufacturer, Bombardier. Although the Westinghouse controllers have since undergone two dozen modifications, Mr. Westfall said, a problem remains with a part called a JBDC contactor, which has tips that are supposed to open and close to complete an electrical circuit but that sometimes fuse shut instead. When that happens, he added, the motor goes dead and ''a car that is designed to be self-propelled becomes a towed piece of equipment.'' Westinghouse controllers are also being installed on 118 older R-28 models being overhauled. Over all, more than 1,500 of the authority's 6,000 subway cars are to be equipped with the devices. Westinghouse controllers are also used on new and refurbished cars on the Path system. But Path ordered ''beefed up'' versions of the device and has avoided the problem, according to Richard Kelly, the vice president and general manager. A Westinghouse spokesman, Robert Henderson, said the contactor tips close whenever a car that is accelerating starts to brake and vice versa, about 2,000 times on a typical day. Sometimes, he said, the tips bounce apart after they close, creating an electrical arc that can fuse them together. In the latest attempt to solve the problem - the fourth, according to the Transit Authority - the company has devised a new contactor unit with shock absorbers to prevent bouncing. It will be tested in 50 subway cars for 90 days beginning this month and, if successful, will be installed on the other cars at no cost to the Transit Authority, according to Mr. Henderson. Law Suit Pending Mr. Westfall said the new unit ''looks very good'' in laboratory tests. However, he said, ''the key is putting equipment into revenue service.'' Last summer, about a year after problems with the controllers arose, the authority ordered 200 more R-68's from a consortium that included Westinghouse and Amrail, the French subway car builder. Although the authority switched last month to Kawasaki of Japan, which built the R-62's, for the final 200 cars in the R-68 fleet, they will again have Westinghouse controllers. That has prompted Amrail to file a lawsuit accusing Westinghouse of breaking an agreement to work only with Amrail on the R-68 project. Mr. Henderson said Westinghouse considered the suit ''without merit.'' Hats Kageyama, manager of transportation systems and equipment for Nissho-Iwai American Corporation, which represents Kawasaki, said the company submitted two proposals to the Transit Authority, one for R-68A's with Westinghouse controllers and one with General Electric devices, and the authority made the choice. |

I'm sure that he can indeed elaborate.Mind you, the article doesn't say what you just said. It speaks speculatively: In the latest attempt to solve the problem - the fourth, according to the Transit Authority - the company has devised a new contactor unit with shock absorbers to prevent bouncing. It will be tested in 50 subway cars for 90 days beginning this month and, if successful, will be installed on the other cars at no cost to the Transit Authority, according to Mr. Henderson. |
