M1/M3 (railcar)
From Wikipedia, the free encyclopedia
The M1 and M3 are two identical series of electric multiple unit rail cars made by the Budd Company for the Long Island Rail Road and the Metro North Railroad and the latter's predecessors, Penn Central (which also operated the LIRR) and Conrail. Originally branded by Budd as The Metropolitans, the cars are more popularly known under their model names, M1 (late 1960s/1970s cars) and M3 (1980s cars). The proper name for the Metro North series are the M1A and M3A respectively though they're colloquially called by the main LIRR designations for simplicity's sake.
The Metropolitans, at the time of their introduction, were arguably revolutionary. With rounded ends and quarter-point sliding doors, the cars resembled long rapid transit cars more than typical commuter rail equipment and provided inspirations to the R44 and R46 series of cars for the sister New York City Subway. Both series were also the catalyst of change for their respective systems. The Metropolitans were high-perormance cars capable of sustaining 100 mph in service, though they were never run that fast. The LIRR upgraded its third rail from 650 vdc to 750 vdc to tsake advantage of the cars' performance. Both the LIRR and then-Central division introduced high-level platforms for all stations in electric territory and the LIRR.

[edit] M1/M1A series
The M1 series were funded by both New York State and the then-fledgling MTA which gained operation of the lines partway though the order. 770 M1s (9001-9770) were built for the LIRR between 1968 and 1973 and 178 M1As (8200-8377) were built for the then-Central division from 1971 and 1973.
[edit] The Cosmopolitans
On the heels of the success of the M1/M1As, the MTA and Budd then made a series of structurally similar cars for the New Haven Line. Built between 1972 and 1977, the M2s (initially branded by Budd as the Cosmopolitans) fully replaced the ex-New Haven EMU cars for use on the New Haven mainline and the New Canaan Branch. Budd and MTA would later licence the design to other manufacturers for updated versions.
[edit] M3/M3A series
In the early 1980s, the MTA began to expand electrification areas of both the LIRR and the then-newly rechristened Metro-North. With the M1 series design proven, the MTA put in an order for similar cars in 1982 with the first trains entering service in spring of 1984. Fully compatible with the M1 series, the M3s had updated elements (largely mechanical, some cosmetic) and a far more subdued interior scheme. 174 M3s (9771-9946) were produced for the LIRR between 1984 and 1986 with 142 M3As (8000-8141) produced for Metro North, arriving between 1984 and early 1985.
This order would be the second-to-last handled by Budd, which in April 1987 left the railroad business after taking the name "TransitAmerica" under which the last M3s were produced under though their builders plates kept the Budd name. The M3's also have the distinction of being one of the last, if not the last, third rail-powered cars to have the "blinking lights" effect at third rail gaps.
[edit] Refurbishment and retirement
With the arrival of the M3 series, the M1 and M1A cars each saw mid-life rebuilds in the late-1980s in order to prolong their useful life. In the mid-late 1990s, smaller overhauls also took place. Still, time began to take its toll on the original M1 cars and by the end of the 20th century the time for the cars was running short.
In 2000, the MTA gave Bombardier Transportation the contract to build the replacement for the M1 series, the M7 series. With the arrival of the first M7s to the LIRR in 2002 and the first M7As to Metro North in 2004, the M1 series began to be slowly retired. The last LIRR M-1 cars were retired in January 2007 while a small number of M1A's remaining in service on Metro-North. In preparation of the retirement of the M1's, the Sunrise Trail chapter of the National Railway Historical Society hosted a "Farewell to the M1's" fan trip on November 4, 2006.
Metro-North plans to keep approximately 30 M1 cars in sporadic revenue service. This will help keep the cars ready for shuttle service to the Bronx when Metro-North builds its Yankee Stadium station on the Hudson Line.
The M3 series is currently in the process of being given a midlife overhaul. One set of LIRR M3s has been given a minor interior makeover somewhat similar to the M7 cars as a test while a set of Metro-North M3A cars is being rehabbed in a different updated scheme.
