There are several branch lines: Salem-Dharmapuri-Hosur-Yeshvantapur, Salem-Mettur Dam and Irugur/Podanur-Coimbatore-Mettupalayem. This network links the railway network in Kerala to the networks in Tamil Nadu and Karnataka, and subsequently other states. HistoryThe first train service in southern India and the third in India was operated by Madras Railway from Royapuram / Veyasarapady to Wallajah Road (Arcot) in 1856. Madras Railway extended its trunk route to Beypur / Kadalundi (near Calicut) in 1861[1] The metre gauge Podanur-Mettuapalayam line was opened to traffic in 1873. The UNESCO heritage track, Nilgiri Mountain Railway was opened in two stages. The Mettupalayam-Coonoor section was opened in 1899 and it was extended up to Udhagamandalam (Ooty) in 1908.[2] The Podanur-Mettuapalayam section was converted to broad gauge in early 2000s. Two {{RailGauge|762mm}} wide narrow gauge famine protective lines were opened in the early years of the twentieth century. The {{convert|25.25|mi|km|0|abbr=on}} long Tirupattur-Krishnagiri line was opened in 1905 and the {{convert|18.5|mi|km|0|abbr=on}} long Morappur-Dharmapuri line was opened in 1906 and extended to Hosur - {{convert|54.5|mi|km|0|abbr=on}} long . The Hosur-Dharmapuri line was decommissioned in 1941 and other two lines were closed around 1945.[3][4] The {{convert|229|km|mi|0|abbr=on}} long {{RailGauge|1000mm}} wide metre gauge Salem-Bangalore line was opened in 1969.[5][6] It was converted to {{RailGauge|1676mm}} wide broad gauge in 1997.[7] ElectrificationThe mainline was electrified in stages. The Jolarapettai-Morapur sector was electrified in 1989-90, the Morapur-Salem (excluded) in 1990-91, the Salem-Erode sector in 1991-92, the Tripur-Waylar sector including Coimbatore in 1995-96, and the Waylar-Vallatolnagar (beyond Shoranur, towards Ernakulam) in 1996-97. The Magnesite-Mettur Dam sector was electrified in 1990-91. The electrification of Coimbatore-Mettuapalayem was completed in 2015.[8][9] Speed limitThe Arakkonam-Jolarpettai-Salem-Erode-Coimbatore-Ernakulam line is classified as a "Group B" line which can take speeds up to 130 km/h.[10] Loco shedsErode diesel loco shed holds WDM-2, WDM-3A, WDM-3D, WDG-3A and WDG-4 locos. Erode electric loco shed holds WAG-7 and WAP-4 and WAP-7 locos. It is home to the largest fleet of WAP-4 locos on Indian Railways and handles some of the longest routes for electric trains in the country.[11] Jolarpettai has an electric/ diesel trip shed.[11] Passenger movementSalem, Coimbatore, Erode and Palakkad, on this line, are among the top hundred booking stations of Indian Railway.[12]References1. ^{{cite web| url = http://www.irfca.org/faq/faq-hist.html|title = IR History – Early days|work= 1832-1869 | publisher= IRFCA| accessdate = 23 December 2013}} 2. ^{{cite web|url=http://www.indiainvites.com/tour_packages.php?mod=det&tid=78&i=1&cid=1 |title=Mettupalam-Udhagamandalam (Ooty) Train |publisher=india invites |accessdate=23 December 2013 |deadurl=yes |archiveurl=https://web.archive.org/web/20131224112012/http://www.indiainvites.com/tour_packages.php?mod=det&tid=78&i=1&cid=1 |archivedate=24 December 2013 |df= }} 3. ^{{cite web| url = http://www.irfca.org/docs/history/salem-district.html |title= Salem District (1916) | publisher= IRFCA| accessdate = 29 December 2013}} 4. ^{{cite web| url = http://www.irfca.org/faq/faq-history3.html |title = Chronology of Railways in India, Part 3 (1900-1947)|publisher= IRFCA |accessdate = 29 December 2013}} 5. ^{{cite web| url = http://irfca.org/articles/manning/salem.html |title = Mysore|work= Bangalore-Salem |last=Manning|first= Ian | publisher= IRFCA| accessdate = 23 December 2013}} 6. ^{{cite web| url = http://www.irfca.org/faq/faq-history4.html |title = IR History: Part IV – 1947-1970 | publisher= IRFCA| accessdate = 23 December 2013}} 7. ^{{cite web| url = http://www.irfca.org/faq/faq-history6.html |title = IR History: Part VI – 1995-1999 | publisher= IRFCA| accessdate = 23 December 2013}} 8. ^{{cite web| url = http://irfca.org/docs/electrification-history.html|title = History of Electrification| publisher= IRFCA| accessdate = 23 December 2013}} 9. ^Coimbatore-Mettupalayam electric train service commences 10. ^{{cite web|url=http://www.indianrailways.gov.in/railwayboard/uploads/codesmanual/IRPWM/PermanentWayManualCh2_data.htm |title=Chapter II : The Maintenance of Permanent Way |publisher= |accessdate=23 December 2013 |deadurl=yes |archiveurl=https://web.archive.org/web/20131203030524/http://www.indianrailways.gov.in/railwayboard/uploads/codesmanual/IRPWM/PermanentWayManualCh2_data.htm |archivedate= 3 December 2013 |df= }} 11. ^1 {{cite web| url = http://www.irfca.org/faq/faq-shed.html |title = Sheds and Workshops| publisher= IRFCA| accessdate = 23 December 2013}} 12. ^{{cite web|url=http://www.indianrail.gov.in/7days_Avl.html |title=Indian Railways Passenger Reservation Enquiry |work=Availability in trains for Top 100 Booking Stations of Indian Railways |last= |first= |publisher=IRFCA |accessdate=23 December 2013 |deadurl=yes |archiveurl=https://web.archive.org/web/20140510115649/http://www.indianrail.gov.in/7days_Avl.html |archivedate=10 May 2014 |df= }} External links
