The Silverliner V is an electric railcar designed and built by Hyundai Rotem. It is used by Philadelphia's SEPTA Regional Rail and Denver, Colorado's Regional Transportation District. This is the fifth generation railcar in the Silverliner family of single level EMUs.

SEPTA Regional Rail

The cars feature expanded interiors and windows, additional entrances and screens used to display information about the service. [5] They are all ADA compliant and meet Federal Railroad Administration safety requirements. [6]

SEPTA ordered a total of 120 cars at a cost of $274 million; [5] the first cars arrived in the United States on 28 February 2010 from South Korea, where they were manufactured by Hyundai Rotem. [5] [6] The cars were built in South Korea and final assembly took place in South Philadelphia. [5] The cars entered revenue service on 29 October 2010 and all 120 were to be completed by the end of 2011. [7] However, due to delays that were reportedly to last until mid-2012, SEPTA is owed millions in fines for the overdue equipment. [8]

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. [9] The agency received some of the trains back in September 2016; but subsequently withdrew 18 cars after and additional defect that was identified as a “clearance issue” that led to minimal, occasional contact between old and new components”. [10] SEPTA announced that it could resume normal schedules on October 3 and would receive all trains by November 2016. [11]

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. [12] 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. [13]

The Fern Rock Transportation Center is a SEPTA rail and bus station located at 10th Street and Nedro Avenue in the Fern Rock neighborhood of Philadelphia, Pennsylvania. Fern Rock serves as the northern terminus and yard for SEPTA's Broad Street Line, as well as a stop for SEPTA Regional Rail's Lansdale/Doylestown Line, Warminster Line, and West Trenton Line.

Pioneer III

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.

A Line (RTD) Commuter rail line in Colorado

The A Line, officially called the University of Colorado A Line for sponsorship reasons, is a Regional Transportation District (RTD) commuter rail line serving Denver and Aurora, Colorado, operating between downtown Denver and Denver International Airport (DIA). During planning and construction, it was also known as the East Rail Line, but most locals refer to it as the A Line. Despite its official title, the line does not serve the campuses of the University of Colorado.

Lansdale/Doylestown Line

The Lansdale/Doylestown Line is a SEPTA Regional Rail line connecting Center City Philadelphia to Doylestown in Bucks County, Pennsylvania. Until 1981, diesel-powered trains continued on the Bethlehem Branch from Lansdale to Quakertown, Bethlehem, and Allentown. Restored service has been proposed, but is not planned by SEPTA. The line is currently used by the East Penn Railroad, serving Quakertown's industrial complexes and distribution centers.

Paoli/Thorndale Line

The Paoli/Thorndale Line, commonly known as the Main Line, is a SEPTA Regional Rail service running from Center City Philadelphia to Thorndale in Chester County. It operates on Amtrak's Philadelphia to Harrisburg Main Line, which in turn was once the Main Line of the Pennsylvania Railroad and is now part of the Keystone Corridor, a federally-designated high-speed rail corridor.

Cynwyd Line

The Cynwyd Line is a SEPTA Regional Rail line running from Center City Philadelphia to Cynwyd in Montgomery County. Originally known as the Ivy Ridge Line, service was truncated on May 17, 1986, at its current terminus at Cynwyd. Track between Cynwyd and Ivy Ridge was dismantled between 2008 and 2010 for conversion as an interim rail trail, preventing service restoration for the foreseeable future. The Cynwyd line is the shortest of the SEPTA regional rail lines, and is the second shortest regional rail line in the United States, with only the New Jersey Transit Princeton Branch being shorter. It is by far the least ridden and least trafficked SEPTA Regional Rail Line. It is fully grade-separated.

The ACS-64 is built at the Siemens factory in Florin, California, located outside of Sacramento.

Silverliner

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 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.

Budd Silverliner

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.
