FH class S01

The FH class S01 is a class of double-deck electric multiple units currently operating on the Metro Cercadas network. The S01 trainsets were built by and  under two orders, the first 45 sets for the line A project and to increase capacity on line C between 2003 and 2007 and the remaining 12 to boost frequencies on line M between 2006 and 2009.

The class S01 is based off Alstom’s platform and resembles the  trains utilised in Paris, albeit with less doors and increased capacity. The first S01 sets initially entered service on line C on March 18, 2003.

Design
The class S01 sets are formed in a double-deck four-car consist with two wide doors on each car. The middle two cars are non-control motor cars while the two non-powered driving trailers are located at the ends of a trainset. The traction system used on the S01 trains since its inception are ONIX 1500 IGBT-VVVF inverters sourced from.

The S01 trains feature longitudinal seating at the vestibules on each end of a single car, with reversible transverse seating in a 2-3 configuration on both decks at the middle of the car. As the first new fleet order for the Metro under Transport for Cercadas (TPC) ownership, the trains are the first to bear an orange-yellow colour scheme in both the exteriors and interiors.

All S01 sets are numbered 01 001 to 01 057.

History
Shortly before the transfer of ownership of the Metro Cercadas brand to TPC in 2001, plans were already laid out for two new lines to the Cercadas Ferdinand Magellan Airport and the Carrazeda Racecourse in the late 1990s. As such, the Herendish National Railways began a bidding process for 45 double-deck and 33 single-deck commuter trains. In February 2001, Metro Cercadas awarded the contract for double-deck trains to a consortium of and, both of which whom were building the  for Sydney Trains at the time.

Parts for the class S01 were built in Alstom’s factory and final assembly took place in the form of complete knock-down kits at EDi Rail’s  workshop. The first S01 trainset arrived at the Port of Turiz in late November 2002, with the TPC accepting the first few S01 trains for testing in December that year.

Revenue service of the S01 trains commenced on March 18, 2003 on line C, after a test run with news reporters and officials the previous day. The S01 later ran the inaugural line A service on May 21, 2004.

In late 2004, twelve additional S01 trainsets for line M were ordered, with the trains briefly running on line R from September to November 2006 and eventually on line M shortly thereafter.
