SEPTA Regional Rail

The cars feature expanded interiors and windows, additional entrances and screens used to display information about the service. [7] They are all ADA compliant and meet Federal Railroad Administration safety requirements. [8]

The cars were expected to arrive in 2005, but due to contract disputes, design delays, and a factory needing to be built in South Philadelphia, they did not arrive until 2010.

SEPTA ordered a total of 120 cars at a cost of $274 million; [7] the first cars arrived in the United States on February 28, 2010 (five years overdue) from South Korea, where they were manufactured by Hyundai Rotem. [7] [8] The cars were built in South Korea and final assembly took place in South Philadelphia. [7] The cars entered revenue service on October 29, 2010, and all 120 were to be completed by the end of 2011. [9] However, due to delays that were reportedly to last until mid-2012, SEPTA is owed millions in fines for the overdue equipment. [10] SEPTA also closed off the very front row of seats due to safety concerns. [11]

The last of the 120 cars arrived on property for testing in February 2013.

Cars 735, 736, 871 and 872 are owned by the state of Delaware. However, they are used systemwide for service, and are not restricted to use on services to Delaware only.

On July 2, 2016, SEPTA removed all 120 of its Silverliner V cars – a third of its fleet – from service due to fatigue cracks in the trucks, leading to reduced service system-wide. [12] The agency received some of the trains back in September 2016; but subsequently withdrew 18 cars after an additional defect was identified – a “clearance issue” that led to occasional contact between old and new components. [13] SEPTA announced that it could resume normal schedules on October 3 and would receive all trains by November 2016. [14]

RTD Commuter Rail

In 2010 Denver's Regional Transportation District selected the Silverliner V for its new commuter rail line. A total of 66 cars were purchased in the married pair configuration for a total of $300 million. The first four cars were delivered to Denver on December 3, 2014, with service to start in 2016. [15] As of 2020, Silverliner V trains are used on the RTD's A, B, G and N lines.

Differences between the RTD and SEPTA cars include support for only 25 kV 60 Hz AC electrification, two center opening high level doors per side, less powerful traction motors, full-width cabs, and bells.

Electromagnetic interference

Some users of audio equipment have found that the presence of tracks carrying Silverliner V cars have introduced detrimental electromagnetic interference to playback and recording of audio. This phenomenon also affects audio and PA electronics inside the cars, although Hyundai Rotem has fitted filters to lessen the effect on internal equipment. [16]

The Pioneer III railcar was a short/medium-distance coach designed and built by the Budd Company in 1956 with an emphasis on weight savings. A single prototype was built, but declines in rail passenger traffic resulted in a lack of orders so Budd re-designed the concept as an electric multiple unit (m.u.). Six of the EMU coach design were purchased by the Pennsylvania Railroad with the intention of using them as a high-speed self-contained coach that could be used for long-distance commuter or short-distance intercity travel in the Northeast U.S. The 6 production Pioneer III units were the first all-stainless-steel-bodied EMU railcar built in North America and, at 90,000 pounds (41,000 kg), the lightest.

<span class="mw-page-title-main">Silverliner</span> Series of American electric commuter railcars

Silverliner is the name given to a series of electric multiple unit (EMU) railcars in commuter rail service in the Philadelphia area since 1958. As of the introduction of the Silverliner V in 2009–2010, there have been 5 generations of Silverliner cars, identified by the Roman numerals I through V placed after the name Silverliner. The Silverliner name came from the classes' shiny stainless steel body shell, which contrasted with the painted and frequently rusting carbon steel railcars used by the Pennsylvania and Reading Railroads between 1915 and 1936. Applied to the first large production order in 1963, the cars made such an impression that the name has since been applied to all subsequent MU classes purchased by SEPTA for the Regional Rail services.

<span class="mw-page-title-main">Budd Silverliner</span> American electric multiple unit railcar

The Budd Silverliner was a model of electric multiple unit railcar designed and built by the Budd Company with 59 examples being delivered starting in 1963. Fifty-five of the cars were purchased for the Reading and Pennsylvania Railroads with public funds for use in Philadelphia, Pennsylvania, area commuter rail service with the remaining 4 cars being purchased by USDOT for use in high-speed rail experiments in 1965. Based on a series of 6 prototype Pioneer III cars built in 1958, the Silverliners represented the first production order of "modern" commuter MU equipment purchased by either railroad and earned their name from their unpainted stainless steel construction which contrasted with the painted carbon steel bodies of the pre-war MU fleets. The cars became a fixture of SEPTA Regional Rail service providing the name to their entire series of EMU railcars before finally being retired in 2012 after 49 years in service.
