station, which has remained in service years since KTM Komuter's launch, albeit with a replacement platform. The layouts and sizes of the new station buildings, as of the launch of the service in 1995, vary by location but are generally divided into two classes: Railway halts, consisting of a small single-storey structure with only ticket counters (a ticket booth, ticket machines and faregates). The stations are usually placed along straightforward dual-lane lines. Medium-sized and single-storey stations, housing both the ticket counters and station offices, and typically stationed along three or more lines. Such stations are typically intended to support additional responsibilities, such as managing railway signals, controlling points and handling goods services. The stations themselves are similar in design to the original wood-based stations along the line with slight hints of Western colonial designs (arches, wooden-and-glass windows and wooden doors), but are larger and modernised. Some stations also have parking facilities. The platforms of the 1995 stations are virtually standardised, down to the design of the passenger semicircle-crossed shelters, the use of similarly-styled foot crossings to link all platforms, and the diamonds-based brickwork of the platforms. Depending on the number of patrons through the years, each station has undergone upgrades or expansions that consist of either increasing the number of ticket counters or opening new facilities for use by passengers or railway staff. Taller, wider canopies were erected on the platforms of most stations to replace narrower, original versions in 2006 and 2007. The pace of the upgrades varies by location. During the 2000s, new stations such as the Mid Valley station appeared in more modern designs, consisting primarily of high, curved canopies above the entire platforms. Certain new stations along dual-lane lines are also included with facilities typically reserved for medium-sized stations, such as the Rasa station. The Kuala Lumpur Sentral station, however, is housed under the concrete base of the transport hub, and is stark and utilitarian in design. Rolling stock The original Komuter rolling stock consists of three versions of three-car EMUs added over the course of three years, beginning in 1994. The EMUs were the first in KTM's history. All Komuter EMUs operate in multiple-unit formation, running from overhead single-phase 25 kV AC 50 Hz catenary supply, with two driving cars and 1 trailer car in between. The EMUs were state-of-the-art, with remote-controlled pneumatic doors, Automatic Train Protection (ATP), train data recorder, wheel-slip control, GTO/IGBT traction
