A traction substation , traction current converter plant , rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage , current type and frequency to supply railways, trams (streetcars) or trolleybuses with traction current .
15-593: Punalur railway station (station code:PUU) is an NSG–6 category Indian railway station in Madurai railway division of Southern Railway zone . It serves Punalur, located in Kollam district of the Indian state of Kerala . The temples related to Sabarimala like Achankovil, Aryankavu, and Kulathuppuzha are Located near Punalur. The Kollam–Shencottah railway line is the first railway line in erstwhile Travancore state and
30-509: Is also finished. Now it is serving as the shortest rail-route from Kochi port to Tuticorin port. Infrastructure of the station will be changed as proposed in tune with handling demands and matching to the glory of past. The Kollam Junction–Punalur metre-gauge railway line to broad-gauge conversion works foundation stone was laid in 1998 at Punalur. Services on the Punalur–Kollam metre-gauge section were withdrawn on 1 May 2007, to facilitate
45-477: Is completed , the trains with electric locos will be operated once the Traction Sub Stations at Punalur and Sengottai are ready. The station presently handles six express trains services to Kollam Junction , Ernakulam Junction , Palakkad Junction , Tirunelveli Junction , Velankanni , Chennai Egmore and eight passenger train services, of which four services ply to Kollam Junction, one of
60-582: Is more than a century old. The Kollam–Sengottai section is part of the Kollam–Chennai metre-gauge rail route commissioned by the British during 1904. The line which was metre gauge has been completely converted into broad gauge and train services started. The first idea of rail link from Tirunelveli to Kollam which was the trading capital of the Travancore Kingdom was conceived in 1873. The line
75-551: Is part of the 325 kilometres (202 mi) Kollam – Sengottai – Tenkasi – Tirunelveli – Thiruchendur gauge conversion project and part of the Tenkasi–Virudhunagar trunk route to Chennai at an estimate of ₹ 320 crore (US$ 38 million). The gauge conversion of the Thiruchendur-Sengottai section has been completed and is open to traffic. In Kollam Junction – Shenkottai section the broad gauge conversion
90-641: The overhead lines or third rail of the traction system, with no feed into a traction current distribution network) or centralized (for the supply of the traction power network , usually in addition to the direct supply of the overhead lines or third rail). Central traction current converter plants are generally found in Germany (primarily in the cities of Neckarwestheim , Ulm , Nuremberg ), Austria and Switzerland , while decentralized traction current converter plants are generally found in Norway , Sweden and
105-765: The conversion equipment usually consisted of one or more motor-generator sets containing three-phase synchronous AC motors and single-phase AC generators , mechanically coupled to a common shaft. Rotary converters were also used, especially where the desired output was DC current from an AC source. In the 1920s, DC was derived using electronic valves ( mercury arc rectifiers ). In modern systems, high-voltage DC ( HVDC ) "back-to-back" stations are used instead of mechanical equipment to convert between different frequencies and phases of AC power and solid-state thyristor rectifier systems are used for conversion from AC power to DC traction power. Traction current converter plants are either decentralized (where one plant directly supplies
120-526: The gauge conversion work on the Punalur–Sengottai section, train services on the section were withdrawn in September 2010. The 49.2 kilometres (30.6 mi) Punalur–Sengottai section gauge conversion works is in progress currently and expected to get completed by 2017. Sections like Punalur–Edamon reach and Sengottai–Bhagavathipuram reach have been completed and open for traffic, Though electrification
135-446: The gauge conversion work. The gauge conversion took almost 11 years to complete after the foundation stone was laid. The 44 kilometres (27 mi) line was converted to broad gauge and inaugurated on 10 May 2010. Express and Passenger train services connecting Punalur to Chennai , Tirunelveli Junction , Palakkad Junction , Kollam Junction , Madurai , Guruvayur and Kanyakumari are currently operational in this route. To facilitate
150-558: The one-kilometer long tunnel between Bhagawathipuram and Arayankavu. The station at Punalur was equipped with locomotive service centre, Parcel and Timber Depot, Train parking bays, Storage Tanks for water and oil, etc. The scenic Punalur–Shencotta railway lies across the western ghats, providing a valuable link across the southern states. The journey through the western ghats is incredible. The station has three platforms, of which two are functional. It also has five tracks used for passenger and shunting purpose. The Punalur–Sengottai section
165-584: The passenger trains run between Punalur and Sengottai, while one pair each run from Punalur to Madurai Junction , Kanyakumari . List of railway stations in India This is a list of railway stations in India . The railway operations are managed by Indian Railways (IR) in the country. Hyderabad Uttar Pradesh Traction substation These systems can be used to convert three-phase 50 Hz or 60 Hz alternating current (AC) for

#1732791754845180-515: The rocky mountains of Western Ghats . The first goods train travelled on this route in 1902 and a train carrying its first passengers began its run in 1904. It makes for a thrilling train journey as it passes over five big bridges and hundreds of tiny ones while negotiating mountain streams and valleys. Passengers are also treated to a breath–taking view of the Western Ghats. The train also passes through five tunnels on this stretch, including
195-405: The supply of AC railway electrification systems at a lower frequency and single phase , as used by many older systems, or to rectify AC into direct current (DC) for those systems (primarily public transit systems) using DC for traction power. The three-phase voltage from the local utility is stepped down and rectified in the traction substations to provide the required DC voltage. Originally,
210-461: Was inaugurated on 26 November 1904. The construction of the metre-gauge rail route between Kollam–Punalur and Punalur–Shenkottai (Ghats section) along the scenic mountain terrain was started in 1873 by the British engineers and was completed in 1902. Travancore rulers in association with the British prepared the plan for the track through the challenging mountain terrain as it involved construction of long arch bridges over steep valleys and tunnels across
225-482: Was sanctioned by the Madras Presidency in 1899 and the survey was completed in 1900.The railway line was built jointly by South Indian railway, Travancore state and Madras Presidency.It was the ruler's desire to create a rail link between Kollam, the then commercial capital of his State and Madras. The meter gauge line from Kollam to Punalur was inaugurated by on 1 June 1904. The Punalur–Sengottai railway line
