M7 rail car
The M-7 is an electric multiple unit railroad car built by Bombardier, with delivery beginning in 2002. The cars were ordered by theMetropolitan Transportation Authority (New York) for the Long Island Rail Road (M7) and Metro-North Railroad (M7A). The M7 replaced theM1 railcars, which had previously provided electric service on these lines. The M7 are powered from an electric third rail.
There are two different versions, owing to the different electrical and signaling systems on the LIRR and Metro-North. The M7 has AC traction motors and can accelerate more quickly from a standing stop than previous MU sets. The two different cars also contain different door-closing lights; the LIRR (Long Island Rail Road) has small red button-sized closing-lights, while Metro-North has white light strips. Unlike the M7s, the M7As have pads behind each headrest. On the M7, the seats face towards the center, but away from the center on the M7As.
The cars are operated in married pairs, with each car containing a complete set of controls for an engineer, conductor, or brakeman. However, the B Cars contain a handicapped accessible restroom, which is larger than the restroom provided on the M1 and M3 railcars and designed to accommodate a wheelchair, as well as an attendant and/or service animal (such as a guide dog, hearing dog or service dog) accompanying the passenger. The enlarged bathroom reduces the number of seats in the car. B cars are assigned odd-number designations.

the M8
The M-8 is an electric multiple unit railroad car built by Kawasaki for use on the New Haven Line of the Metro-North Railroad.[1] [2] The cars were ordered by the Connecticut Department of Transportation which has ordered 342 cars out of a total 380 cars, the rest of which are still on option. The M8 improves on the design of the M-7 car used on the Harlem Line and the Hudson Line.[3] It will replace the 240 M-2's which have been in use for over 30 years.[4] Current schedule calls for an eight car test train to be delivered late 2009.[5] Full production of the M8's is to begin in early 2010 and the cars are to be delivered at a rate of 10 cars per month[6] until delivery is completed in late 2012. The M8s will differ most from the M7s in that they will have both third-rail and catenary electrical power. The M8s will be able to pick up 750 Volt direct currentpower from third rail via shoes for operation along the New Haven Line from Grand Central to Pelham, 12,500 volt alternating current power fromoverhead lines via pantographs for operation from Pelham to New Haven (as well as along the New Canaan Branch), and 25 kV AC power from overhead for operation along the Shore Line East route east of New Haven. Unlike in earlier classes, changeover between the two AC voltages can be made by the engineer while on the move.[7]
As of Aug 6, 2010, Governor Rell has approved expansion of the purchase order by an additional $226.3 million to cover all options, bringing the fleet total to 380 cars. [8]
In response to rising number of people seeking to use their bicycle to solve the "last mile problem" between Metro North stations and destinations, ConnDOT has pledged to provide hooks for storage of two bicycles in the disabled riders area of each rail car. In the event that a disabled rider boards a car, all cyclists must move their bicycles to the entry vestibule. The effort to procure bike hooks is in fulfillment of a letter from Governor Jodi Rell on June 6, 2008 directing "that the new [M-8] rail cars provide adequate bicycle storage." As of October, 2009, Metro-North and ConnDOT have issued a Request for Information (RFI) to vendors of bicycle hooks and are moving forward with issuing aRequest for Proposals (RFP). The most suitable bicycle hook will then be selected from among the solicited proposals. In spite of the planned hook installation, during peak travel periods only folding bicycles are permitted aboard most Metro North trains.

MTA NYC Transit Takes Delivery of Final Set of New Subway Cars
MTA NYC Transit Takes Delivery of Final Set of New Subway Cars
The final units of the 1,662-car order of brand new R160 subway cars have been delivered to MTA New York City Transit and are in service. Like the preceding orders of new technology cars, the R160s have brightly-lit interiors, crystal-clear digitized voice announcements, advanced heating-ventilation and air conditioning systems (HVAC) and a smooth air-cushioned ride.
The gleaming new-technology cars were unloaded from flatbed trucks in May and rolled into the system at the 207th Street Maintenance Facility. They were paced into service along the lettered lines less than a month later.
The cars were built as a joint venture by Alstom and Kawasaki, and funded in the MTA's 2005-2009 Capital Program with monies provided by the Federal Transit Administration. Deliveries of the cars began nearly five years ago and since then, the fleet has earned a reputation for high reliability, recently operating an average of more than 370,000 miles between mechanical failures.
Other features include digital information boards and the Flexible Information Notice Display (FIND) system, which incorporates a video screen, scrolling station names as the train progresses and a route map that can be changed if a train switches to another line. And, like the new technology R142 cars that have been in service since late 2000 on the numbered lines, the R160s have an advanced heating and cooling system which is designed to be easier to maintain than the units in older cars.
"A lot of work went into the development of the R160 fleet and these cars have allowed us to retire hundreds of subway cars that first entered service in the mid to late 1960s, said Carmen Bianco, Senior Vice President of the Department of Subways. "These cars are state-of-the-art, and designed to provide customers with far more information and comfort than older models and they are designed to last at least through mid century."
The R160 cars have several advanced operating and maintenance features, including computer-monitored throttles and speedometers for better control and smoother ride and an onboard, computerized diagnostic system that allows quicker repair when a failure does occur. The new technology car fleets (R142/A, R143 and R160) have proven to be extremely reliable.
Gone from the rails are more than 1,500 subway cars in service for more than 40 years. The majority of these cars have been stripped, cleaned and placed on the Atlantic seafloor where they joined more than 1,000 redbirds as artificial reef material. A lucky few have ended up as exhibits in the MTA's New York Transit Museum in Brooklyn Heights—a great place to catch all of the trains you've missed.

Countdown Clocks" Continue to Pop Up on Subway Platforms
Subway customers at 40 stations are now able to take advantage of next train information as MTA New York City Transit continues to turn on customer information screens in the ongoing effort to provide riders with real-time train arrival information. The system is being activated incrementally, now more than halfway toward the 75 station goal for 2010. NYC Transit hopes to have 152 numbered line stations on line in 2011.
The Customer Information Screens are taking the guesswork out of knowing when the next train will arrive, joining the 24 L line stations that introduced the program in January, 2007 through the line's communications-based train control system. In recent weeks, these "Countdown Clocks" have been added at 40 additional stations on the number lines in Brooklyn, the Bronx and Manhattan where riders are no longer forced to lean over the platform and scan for oncoming headlights.
A and C Line customers at six stations in Washington Heights and Harlem will also benefit from a new pilot project testing the delivery of next train arrival information utilizing previously installed electronic signs tying them in with existing infrastructure. Unlike the more advanced system currently being turned on along the numbered lines which receives its information from the scheduled data provided by ATS (Automatic Train Supervision), this simpler system identifies train location using the signal system's track circuits and sending this information to existing equipment. This method allows NYC Transit to get the "Countdown Clocks" up and running as quickly as possible at very little added expense.
"These countdown clocks are another way we are fundamentally changing the customers' experience using our system by connecting them with 21st century technological advances," said MTA Chairman and CEO Jay H. Walder. "Despite tough economic times, we continue to move forward in modernizing our communications network, finding creative and affordable ways to better service the riding public."
The Public Address Customer Information Screen (PA/CIS) provides train arrival messages in audio and video. The messages indicate when the next two trains are due to arrive at the station and their destinations. Screens are located on the platform and near turnstiles where passengers can view arrival information before paying their fares.
"We are moving ahead steadily with this vital customer information initiative," explained NYC Transit President Thomas F. Prendergast. "With the PA/CIS screens activated on a regular basis across the system, more and more subway riders will be able to just look up and see when their train will arrive."
