The LIRR third rail used to be 660 vdc, as was the New York Central RR underrunning third rail. The extra 10 percent was supposed to give the trains a little extra oomph, and help counteract voltage drop with distance from the substations. The boost to 750vdc is further in that direction With a third rail that stretches 326 miles, zapping 750 volts of electricity into hundreds of trains a day, and a system so expansive that fencing it all is impractical, the LIRR's charged metal rail is a hazard to anyone who steps onto the tracks
The LIRR, established in the 1830s, electrified major segments with third rail between 1900 and the early 1930s, and replaced steam locomotives with diesel-electric units between 1926 and 1955. The Oyster Bay Branch was electrified as far as East Williston in 1934 SUB - STATIONS SUB-STATIONS CONVERT HIGH VOLTAGE ALTERNATING CURRENT TO LOWER VOLTAGE DIRECT CURRENT AND CONTROL ITS DISTRIBUTION TO THE THIRD RAIL. TRANSFORMERS LOWER THE VOLTAGE FROM 11,000 VAC TO 650 VAC WHICH IS THEN CONVERTED TO DIRECT CURRENT
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track.It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the. The dual mode DM30AC's had 4 chopper modules with inductors that raised the 750 VDC third rail up to the max 2,800V; they were set to pull up to 3,900A from the third rail. IIRC, the LIRR third rail breakers trip at about 14,000A
The 3rd rail for top running shoes is mounted to the bracket via the bottom of the 3rd rail. The 3rd rail for bottom running shoes is mountedf to the bracket via the top of the 3rd rail. I am asking if instead of mounting the 3rd rail from the top, shown here: or having bottom mounting, shown here: Note the green box, it is the bottom mounting The Long Island Rail Road wants to be the first commuter railroad in North America to run battery powered trains. It will begin a nearly $1 million analysis of its electric trains on the Oyster.
In all, when the LIRR Expansion Project is completed, eight railroad grade crossings will have been eliminated, seven bridges replaced or expanded, five stations completely rebuilt, 10 miles of a third track installed and infrastructure such as power substations and interlockings built The third rail in the MBTA system is a steel conductor rail that provides 600v D.C. power to the subway cars on the Orange, Red, and Blue lines. The electricity that is constantly flowing through this steel rail is then picked up by the trains as they drive past. Each train in the system is equipped with two steel shoes that jut out from each.
An ironworker involved in the Long Island Rail Road's (LIRR) third track expansion project was electrocuted on March 14 and is in critical condition. The accident happened during the erection of a pedestrian bridge at the Mineola station. A crane that was being used for the construction hit a high-voltage line, injuring the worker The Metropolitan cars were also the catalyst of change for their respective systems as the high-level boarding required all stations in the electrified zone to be rebuilt from 1966-1968 and the increased power demand forced the LIRR to update its third rail power supply from 650 V DC to 750 V DC to take advantage of the cars' performance. On. If all goes as planned, in about one year, MTA Long Island Rail Road will be testing a prototype BEMU (battery-electric multiple unit) that operates on third-rail power or batteries on the 13-mile, non-electrified Oyster Bay Branch. The program, a venture with Alstom, will be North America's first test-of-concept of this application on commuter railcars LIRR to test battery-operated trains to travel on diesel branches. SentinelOne Exceeds IPO Goal to Raise $1.2 Billion. Cramer's Mad Money Recap: Facebook, Merck, Nvidia. The Long Island Rail Road.
President of the Metropolitan Transportation Authority's (MTA) Long Island Rail Road (LIRR), Phillip Eng, has announced that LIRR has entered into an agreement with Alstom to test batteries that could enable electric railcars to travel on the railroad's diesel branches.. Upon successful completion of an eight-month initial analysis, technicians will retrofit a two car-long electric train. The third track will reduce congestion and delays along the main line for a total of 9.8 miles. From Floral Park to Hicksville, commuters are eager for relief. The overall project is expected to. If batteries succeed on the LIRR as they have for light rail in Europe and Asia, the use of battery-powered railcars promises over the long term eliminate the need for transfers to a separate diesel fleet to reach the railroad's expansive unelectrified regions extending 160 miles from East Williston to Oyster Bay, Huntington to Port Jefferson. This is necessary to pay for planning, design and engineering, environmental review, land acquisition for construction of power substations, expansion of commuter parking, potential relocation and/or consolidation of existing stations, new stations and platforms, new electric Multiple Unit car storage yard, new track, third rail and signals Apr 20th, 2021.

Credit: Howard Schnap LIRR's prototype BEMU will be a two-car Bombardier M7 married pair, with four of the car-set's eight traction motors (one per axle), which normally draw power from 750 VDC third-rail, retrofitted with battery propulsion. LIRR had begun discussions with Bombardier on the project prior to Alstom's acquisition of Bombardier; the program is. The train would run on third rail power and charge the batteries while on the electric portions of the route, then switch to battery power on the unelectrified segment between East Williston and Oyster Bay. People have been talking about extending electrification to various segments of the railroad for generations, Eng said There are 104 substations on the LIRR across all areas of the Rail Road's electrified territory. At each of these substations, AC voltage is converted to DC voltage and safely fed to the third rail out on the tracks. This electrical power then energizes each train's traction motor, which propels the train
Third Rail. A third rail is a method of providing electric power to a railway train, through a continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment By N Miller. OYSTER BAY, NY-MTA Long Island Rail Road President Phillip Eng on April 19 th that the LIRR has entered into an agreement with Alstom to test batteries that could enable electric railcars to travel on the railroad's diesel branches. Upon successful completion of an eight-month initial analysis, technicians will retrofit a two car-long electric train to operate on battery power. Haqving that kind of voltage on a third rail would result in shorts, because of the short distance from third rail to ground rail, the running rails. But one could design high speed trains using 1000V DC or 700V AC which would be safe with third rails, but nobody seems to want to go that route LIRR's Third Track Gets Key NY Senate Approval to Move Ahead. While thousands of daily Long Island Rail Road commuters cope with service disruptions as Amtrak makes emergency repairs to Penn.
Officials from the 3rd Track Constructors, the organization working on expanding the Long Island Rail Road, announced that expansion work will be temporarily halted to review safety protocols The M8 is similar in design to the M7 car used on the Harlem Line and the Hudson Line.Like the M7, the M8 is able to pick up 750 Volt DC direct current power from underrunning third rail for operation along the New Haven Line from Grand Central Terminal to Pelham, where the traction power source is transferred to the overhead catenary wire.The overhead wire is at a nominal 12.5 kV AC power. While on electric portions of the route, the train would run on third rail power and charge the batteries, then switch to battery power for the unelectrified segment between East Williston and Oyster Bay. If successful, the LIRR would ultimately be able to carry passengers directly between Oyster Bay and the railroad's terminals in New York.
