You also failed to take into account the TA has deliberately degraded the performance of their entire fleet from original spec, the final trigger was the Willamsburg Bridge disaster.Do you have evidence that the R160s are capable of accelerating at a greater rate than they achieve in service? Because the numbers disagree with your qualitative assessment. Nonetheless, I still get a jolt sufficient to knock me down and have to hold on at times when an R32 starts up from a dead stop You're describing the jerk rate, the rate of change in acceleration, not acceleration itself. And even then an NJT Arrow is capable of knocking people over when it departs a station despite an even lower 2mph/s acceleration. I have been at the RFW - you have not. And you had a precise accelerometer measuring the rate of acceleration while the train achieved the performance you claim it did, right? Because otherwise your qualitative assessment of rolling stock performance is absolutely worthless. It's just as worthless as my assessment would be in the face of numerical evidence I was incorrect. Unless you can find numbers showing the train reached 3mph/s your claim is false. That is not "foamer nonsense" as you put it. You're making a counterfactual claim based on nothing more than how the acceleration "feels" when you're leaving noseprints on the foamerglass. That's the very definition of foamer nonsense. |

I'm not as familiar with the B division cars, but the A division cars on the Lex Ave take off like a rocket ship.No, they don't. At least not to any greater degree than the R160s do. And the M-8's, while FRA heavy rail, are pretty close to that, and they weigh a lot more than any subway or rapid transit car. The fact that you think that, despite the M8s accelerating at 2mph/s, one third the acceleration of a HBLR Kinki-Sharyo LRV (and most LRVs, PCCs, and so on), shows just how flawwed attempts to determine acceleration through qualitative observations are. If SIR has a power issue that stops them from running rocketship-like trains, then upgrade the substations. ... Electric railroads should not be operated around the limits of their power supplies. Their power supplies should be upgraded to support the worst-case scenario imaginable in terms of power draw. Unfortunately there is a limited amount of money to go around. Replacing the rectifier/transformer sets in the substations to increase capacity at a time when the rolling stock is due for replacement may be needlessly expensive. Additionally there is a safety aspect to limiting the current that can be drawn through the substation equipment. |

Battles with FRA and UTU are battles, regardless of LRT.But they're made a lot easier if you're removing the rail line from the national network. The FRA is going to argue that by replacing the R44s with similar subway cars there is no sufficient reason to change the status of the line. But by going to LRVs there will be more than sufficient cause to remove the line from the national network, which should have been done decades ago. People are not going to dawdle off the Ferry and evenly distribute themselves between the 2 trains. Who said anything about distributing themselves evenly? An LRV based train isn't going to be half that of a 4 car R44 train. It'll be somewhere on the order of 66-80% that capacity, which will allow passengers to crowd one train or another. If the Ferry is late, you can't jam them all on the later train. Actually, you could. A 4 car R44 carries 720 passengers. A 3 car train of NJT Kinki-Sharyos would be slightly shorter and hold 600 passengers. Going to an LRV which is a bit larger would close that gap. I DID say Secaucus - Times Square will take 16 minutes because the Parsons report said so. Oh good, so you do know what numbers are and how to do a quantitative assessment. I also said your LRT scheme AVERAGES 2 minutes over the lenght of the route savings, not 5 minutes savings. That's not how a change in schedule time is computed. It's entirely erroneous to claim that just because 2 minutes are saved at the midpoint then 5 minutes aren't saved at the end points. It's still 5 minutes, your attempts to sandbag the numbers that don't support your baseless claims aside. Your alleged lightweight LRV for SIR is purely imaginary. It is neither an NJT nor NFTA car. So you can't claim anything about better performance. I haven't specified a particular model because you could easily go to Alstom, Bombardier, Siemens, CAF, Stadler, or almost anyone else and get them to build you an LRV which has a 42" floor, 60 to 80 mph top speed, and accelerates at 3mph/s. They'd more than likely be able to build those cars based on one of their existing designs, thereby saving significant amounts over custom NYCT cars. In case you haven't notice, WMATA does not buy lightweight, aero-aluminum, telescopic junk anymore, but heavier, stainless cars. You do realize the R160s are 1.4klbs/ft, while the WMATA 7000s are 1.0klbs/ft, right? A difference of nearly 150% is a very significant increase. Yes we can change gear ratios and still preserve adequate speeds. SIR trains need not go 70MPH. No. You cannot. That might be an option if they were to go with an extensive rebuild. But there is no way anyone would contemplate doing it to whatever cars awaiting the scrap line that SIRT may get in the interim. |

You have no idea what it is like to go against the FRA, and then you wish to go on UTU union busting exercise for no gain.The same simple 9th grade Algebra that says 14 miles taking 42 minutes is 20MPH, says 22 MPH takes 38.2 minutes. So yes, that is 4 minutes time saved, not 5. You were the one that introduced 20 and 22 MPH. The 42 minutes is the current timetable. There are no more unknown variables. You simply miscalculated. There is nothing erroneous that says that 2 is half of 4 and 7 is half of 14. As usual, your thought process can progress beyond the train reaching the bumper block at St George, just as you did not car about leaving passengers 18 stories down in Macy's Bunker. They do have to eventually get out of there and go to work. Your scheme of splitting passengers onto indirect ferry connections adds to trip time. So you have no time case to be made. Only a techno-nerd like you believes in manufacturer data sheets. As you well know, all MTA operators seriously downgrade all their rolling stock in testing, both on LIRR/MN and NYCT, and they mean nothing. Gear ratios can be altered in the DESIGN process. No said to do an extensive rebuild. The R44's were built to run at 80MPH. There is no reason for new subway cars to do that. Weight alone does not determine acceleration rate. There are gear ratios and there is horsepower and there is supply amperage. |

We have evidence that ALL rolling stock was downgraded, and so the R160's were built that way as there was no reason to do better.An Arrow could do 2MPHPS. The lighter LIRR M-1 could only do 1.5MPHPS because its performance was downgraded before being placed into service. I am still waiting for the 20% reduction in running times that Budd promised over the MP54, like 52 minutes to Babylon. You are the true foamer, believing in manufacturer data sheets, and can't let go of a failed argument that nobody else agrees with. You sarcasm says it all as well. You'd fit right in with the characters I have seen on fan trips (that I no longer go on). |

We know in the real world, the R44 was a shitty car, and the TA had to do several rebuilds on their propulsion and braking systems to get them to perform and get their MDBF acceptable. The current SIR car is much different than what last ran on the IND, and nothing like when Pullman delivered it. |

Right, I was thinking R46 at that point when I was typing.St Louis was not known for building great cars with good bodies at that point. At least Pullman proved themselves with the R46's and the Superliners. |

Your convenient amnesia has also forgotten that the NJT LRV cars once lengthened will produce a 5% reduction in performance.Apply that to 3.0 MPHPS, and you are down to 2.85 MPHPS. Bulk it more with a high, subway car level floor and a 10' width, and it degrades further. So your imaginary, sooper-dooper LRV car closes in pretty close to an R160 spec of 2.5 MPHPS. And that is before we do anything about substations. |

I don't know about "incapable", but the answer is, as told by NJT's LRT contractor, that there will be a 5% degradation in performance, and they will tolerate it. |

I've never been on anything that could take off like the Lex Ave Line.The people issue is rapidly disappearing as lines get converted over to CBTC, which should also eke out a little bit of time on the schedules, as they can wait until the absolute last second to slam on the brakes and platform perfectly versus a human driver who needs some margin. Commuter trains could do the same thing, although I'm not sure what the regulatory hurdles would be of programming them to run themselves. Not rocket science once you have PTC, it's just a software upgrade. |

Like I said, I'm not as familiar with the B division equipment, and the lines I happen to ride on B division are usually run with older cars.A limited amount of money definitely would rule out any crazy light-rail ideas here. Standardize on subway equipment like it is already set up to handle, and take it from there. Beefing up power infrastructure is a relatively cheap way to get more performance out of the existing trains if it is needed. |

What made a lot of difference on the LIRR was not only replacing 15 ancient substations in the late 1960's or early 1970's with 45 solid state ones, but gradually upping the nominal 3rd rail voltage from 650 to 750.We all know the leisurely BMT Standards took on quite a different personality when sent on to the Queens Blvd line in the late 1950's, which had better 3rd rail power than the BMT. I do hope HBLRT someday gets to Staten Island, though not sure if it can with the Bayonne Bridge raised. But that is not the car to be also run on the main From St George to Tottenville, and they belong to NJT. There is no economy of scale to a huge MTA system in having a tiny SI fleet of the equivalent of 64 75' cars when there is little chance of light rail anywhere else in the city. If it comes to 42nd or 34th Streets, it won't be a high floor SI car. |

The only reason why the C train have some new cars (temporarily I might add) is because of the awful air conditioning issues that its 51 year old fleet have. Once summer is over the C will be 100% R32s. |

Then maybe the R160's do tooNo. They don't. We have the numbers, I posted them here for you to review. We know they accelerate at 2.5mph/s. That is an unassailable fact. Qualitative assessments by foamers need not apply. A limited amount of money definitely would rule out any crazy light-rail ideas here. Standardize on subway equipment like it is already set up to handle, and take it from there. Beefing up power infrastructure is a relatively cheap way to get more performance out of the existing trains if it is needed. But that's the most expensive option possible. You're talking about changing both the rolling stock and the power infrastructure over the next decade or so. Going to LRVs would allow the rolling stock to be changed out while the power infrastructure improvements are pushed off another decade or two. |

There you go again with the meaningless data sheets.Yes, how dare I make an argument grounded in facts and numbers when I could do like you and argue from questionable anecdotal evidence? Upgrading voltage and substations has been done repeatedly over the decades to LIRR and MN. It can be done on SIR. What makes you think SIR is going to get the capital budget of the LIRR or MNRR? LRVs allow us to forestall improvements to the power infrastructure while changing out the rolling stock through end of life attrition. |

The same simple 9th grade Algebra that says 14 miles taking 42 minutes is 20MPH, says 22 MPH takes 38.2 minutes. So yes, that is 4 minutes time saved, not 5.Lets leave subjects that are apparently far beyond your ability, like 9th Grade algebra, alone and instead focus on 3rd grade rounding. It's 5 minutes. As usual, your thought process can progress beyond the train reaching the bumper block at St George, As usual I come up with a superior solution and you rant and rave about how it cannot be done and how it'll be the worst thing ever. But the numbers definitely favor converting the SIRT to LRT. Only a techno-nerd like you believes in manufacturer data sheets. Aw, I'm sorry. Here I made you look quite the fool with your ridiculous defense of how a railcar acceleration "feels", so you feel the need to dismiss the numbers now. Why don't you just quit while you're WAY, WAY behind? As you well know, all MTA operators seriously downgrade all their rolling stock in testing Those sheets are based on specification, not some as-built test data. The MTA specified a 2.5mph/s acceleration. There is no downgrading involved. Your whole argument is completely and utterly fallacious. Gear ratios can be altered in the DESIGN process. I thought your argument was that the R44s needed to be modified to provide a higher acceleration rate. Sure, if they were getting new rolling stock that'd be a possibility. But by the time you do that economically you'd end up with something about the size and weight of an LRV. |

I do, he can't round numbers and feels the need to make arguments to the second. If that's not the surest sign he's flailing for the thinnest of reeds after making a fool of himself, I don't know what is. |

The extended NJT Kinki-Sharyo LRVs achieve that acceleration rate with just half the trucks powered. The R160 pokes along with every axle powered. |
