Great,so order some thing like these:It'll be largely mechanically compatible with whatever LRVs are ordered for the North Shore Line,and it'll still use the high platforms and third rail. How is the vehicle shown in the picture you posted substantially different than a typical metro vehicle? Who said anything about changing the South Shore line's infrastructure at all? Leave the third rail and platforms alone. Just order rolling stock which delivers some synergy with the rolling stock that would likely be utilized by the North Shore line. You said you wanted to order LRVs for SIR. If something is totally grade separated and using high platforms, IMHO its not light rail anymore. There's no reason light rail cannot be grade separated if the structures are in place and are structurally sound. But while the structural soundness or replacement of the elevated structures is critical to the implementation of a heavy rail line using subway cars it is merely optional with a light rail alternative. The LRT offers the possibility of taking down a particularly difficult to replace segment of structure and running at grade along the segment. It'd even be possible that they'd utilize some amount of street-running if that were required by local pressure. In any event,the North Shore may have some grade separated elements,but it's definitely not fully grade separated. The approach to St. George will require a tremendous amount of work for a heavy rail line,particularly threading the heavy rail line along Richmond Terrace. Light rail opens up alternative approaches to implementing the line which may ease local opposition. If you're going to go to the trouble of building rail infrastructure, I would think we would want to keep it grade separated. If we're going to make significant parts of the line street running, then maybe the studies evaluating BRT will show that it is a better option. As we all know, MTA doesn't exactly have plentiful capital dollars laying around. The March 2004 study by URS for the SI Borough President and the Port Authority found that they could not keep O&M costs under the limit of $10 million a year if they ran the heavy rail mode at the same 12 minute headway that was proposed for all other rail based modes. The two person train operation presumably was simply too expensive. As a result the heavy rail mode was constrained by its costs to a 15 minute headway. This meant the LRT mode was projected to be capable of carrying around 2200 more passengers per day at around two thirds the annual O&M cost ($5.62 million vs $9.06 million) and 20 million dollars less in capital cost ($351 million vs $370 million As SEPTA has demonstrated with the Market-Frankford line, and NYCT has shown with the crosstown line, you can operate heavy rail with OPTO. A SIR north shore line would likely have ridership capable of such an arrangement. Additionally, just because the capacity would be there doesn't mean it would be used. The present SIR doesn't operate anywhere near 12 minute headways for most of the day. At the end of the day, how would a "light rail" vehicle that was designed for high platforms, ran on 3rd rail and matched NYCT car dimensions be significantly different from a heavy rail vehicle that did the same? You would essentially be able to take such a vehicle and put it on any subway line. For that matter, why couldn't you take an R68, strip its existing power collection system, throw catenary on it and run it on the street? Chicago's South Shore line runs even heavier vehicles in the street. I think we're getting to a point where making rigid descriptions of separate modes only serves to hinder what a comprehensive transportation system is capable of. So to be clear, if the light rail vehicle you want to see comes complete with high platform boarding and the ability to run on 3rd rail and catenary, I'm all for it. |

The LR/HR issue is bogus. CTA has third rail on the ground w/grade crossings,Cleveland has catenary LR/HR mixed equipment w/platforms to match.You can have grade crossings with 3rd rail, but not street running. Also, you can mix low and high platform equipment, but they can't stop at the same platform. To me, that's the only tangible separation of modality. Rapid transit can serve low platforms (typically as light rail) or high platforms (as "metro", or heavy rail), but not both (typically because such solutions would either sacrifice time to vehicle capacity). Commuter rail can operate vehicles that accommodate both. |

Chicago North Shore & Milwaukee were high/low, and had both third rail and overhead trolley. Today, San Francisco lrvs are both street (low platform) and high platform (in the subway). Karlsruhe, Germany has lrvs that are similar to San Francisco (high/low platform) and also operate on the Deutsche Bahn (national railway system), sharing facilities with Acela-type trains and high speed freights. These are just a few examples; I suggest you check these out before saying "it can't be done." It has long ago and in the present. |

The C, however, is not exactly packed with riders. Full length trains would be nice, but I'd rather see improved headways before full length trains. [The A and C] both share the same yard Not really. The C is 207, the A is Pitkin. At any rate, they're totally different fleets. The A doesn't run R32s, and the C doesn't run R46s. Nothing would change after the R179 arrives. Well, nothing except roughly 40 R179s will be in 5 car sets and the C's spare ratio will decline, so the Eastern Division will get R179s as well. |

My typo not withstanding (should say or, not to in the parenthetical), I made it pretty clear that it indeed is possible to procure vehicles capable of handling both low and high platforms, but that such a solution sacrifices either time or capacity. The LRVs you mentioned do just that. |

This uniformity that you would like would cause purchase of 36 more cars (18 trainsets). We don't need them. For that money, we could re-fleet half of Staten Island.I'd cut back 50 cars from the M-9's, overhaul M-3's for Brooklyn Shuttles. It would be an easy, in door life for them. If its saves $50M, there are plenty of other better uses for it. |

Don't forget the entire CTA and I believe also Boston's Blue Line and also Philly's Broad St Line. As I mentioned in another post, the distinction between heavy and light rail has become rather fuzzy since there are so called light rail systems that are high platform and grade separated. |

No, there's no truly fuzzy distinction. Heavy rail still has trains of up to eleven cars. High platforms and grade separation don't mean anything in particular.They may share rails in Cleveland, but that's a traditional setup that wouldn't be paralleled today if it were new-build. |

Not that different from how the TS S cars having to get to Livonia.I mention R46s because they have AA pairs and you can have those replace those R68 singles it currently runs.

Longer C trains would be fewer C trains (same total amount of cars running, but a few less crews*) running and with that extra room you could run more A trains.*80 cars now is 10 trains. But with a longer train you have 8 trains and a possibility to add an extra A train if needed. There's no need to restrict the C to shorter trains. |

It is better to have a surplus than a shortage.R143s may have filled the void left by the premature retirement of the R27/30s, but weren't enough to meet the growing demands of the L. At least if the C gets 10 car trains (only to run fewer trains), there's always room to add more trains to that line if it ever needs it. |

I remember reading here about 242nd being closed down (temporarily or permanently and moving the operations to 207th). So if I'm wrong please correct me. |

PCCs operated on the streets and in the old tunnels--Sunset Tunnel on the N Judah streetside stops both ends nothingt bunderground, and the Twin Peaks Tunnel from Castro/17th to West Portal. The latter had two "subway" stations--Forest Hill and Eureka. The Eureka platform is still there for emergency egress, Forest Hill was converted to high platform. In low platform days the West Portal stop was on the street--now it is a station built partially into the hill. |

Understand that a practical balance must be maintained between consist capacity and headways. For example: the MTA could cut the headways of the G train in half and turn the G into full length trains. This would result in the same theoretical capacity on the line and would save on crews as you and randyo point out. However, it would also result in a rush hour headway of almost 15 minutes!The C already features some pretty poor headways (so poor that I walk an extra 4 minutes to an express stop). Reducing its headways and running longer trains would be a serious disservice to local riders on Fulton and CPW. Additionally, the A doesn't really need more trains, it just needs more even spacing. At its peak, the A operates 18tph from Brooklyn during the AM rush. Without reducing C headways, one could increase that number, but the CPW express tracks are already close to max capacity, with 18 A's and 10 D's. Leave the C at 8 cars, and if anything, cut the wait time for it. |

Then why did 4018 come away (relatively) unscathed at Woodley Park back in November 2004? 1077's apocalyptic damage can be understood, but I wasn't aware that the 4K cars had that issue too.1077 is more then 25 years older then 4018. They also have 25 more years of wear and tare on them and were driven much harder and faster during the first 15 years of the life then their younger brothers and sisters. It take years before there are viable signs of medal fatigue. John in the sand box of Maryland's eastern shore. |

What was the purpose of having high platforms in the Market Street MUNI tunnels then . . . ?Arguably, the same reason that Frankfurt went high platform for their Stadtbahn, superior loading characteristics and reduced dwell time at core stations. Mind you, most of those advantages went away with the development of 70% low-floor Stadtbahn units. |

Originally BART was to be double deck w/ the upper level taking over the Twin Peaks Tunnel to...maybe St Francis Circle? So the Muni platform are dimensionally the same as the Bart one level down. Further, at the Civic Center Station the stairs were clearly designed for plat to plat transfers. SS caging/handrails were an afterthought. On paper, the Muni Central Control bunker built above the West Portal station was a BART project. |

Both CIYD & 207th are overhaul locations for all NYCT & SIR equipment. Most of the cars up on horses at 207th Street have been IRT A Division equipment in part because all but one of the IRT's main line yards are located in the Bronx. IRT cars have easy access via a ramp from the Broadway #1 line into 207th Street YD.207th Street Overhaul Shop is responsible for repairing any problems that pertain to the subway car itself. This will include anything from a simple truck change to major carbody repairs. Along with running repairs, this shop is responsible for maintaining a Scheduled Maintenance System (SMS) program as well. In 2010, the Car Repair Shop was responsible for the SMS on the R-142, R-142A and the R-62 car classes. This consisted of work on all major subsystems of the subway car such as Air Brake, Propulsion, Trucks, Electronics Systems, Doors, Carbody and HVAC. The Car Repair Shop removes components from these subsystems and ships them to the various support shops that then overhaul these items. The parts are then returned to the shop for final assembly on the car and testing. The Car Repair shop also is responsible for replacing any items on the car that cannot be overhauled in a support shop. In the past year they have replaced over 800 trucks, 1200 Door Operators, 700 Modular HVAC units and 800 Propulsion Units while also rebuilding over 900 Draftgears and 50 split system A/C systems. In 2010 a major change to the propulsion system on the R-62 was begun. The original SCM based propulsion system is being replaced with an electronic controlled propulsion system or E-Cam. This requires the replacement of the entire Group Switch Box and Resistor Grid Assemblies. This system was prototyped in 2010 and production was completed on 85 cars with the rest of the cars to be completed this year. The running repair staff also has been instrumental in maintaining the fleet of cars that are owned by the New York City Transit Museum. These cars have been painstakingly restored from years of neglect to bring them back to a state of repair that allows them to be used in passenger service on excursion trips throughout the year and during the Christmas Holidays. While the primary focus of the Car Repair Shop is to keep cars “In Service”, they have also become experts at scrapping cars that have reached the end of their life cycle. Special Projects and Prototypes: •Provided museum cars for excursion throughout the year •Restoration of the museum car 4902 •Car 6660- Removed flip up seats & heaters •Conversion of 85 R62 General Electric group box to an E-Cam system •Salvaged propulsion components from (44) R44 scrap cars to support the R68 SMS program in 2011 |
