Trains on this route are expected to run at <strong>maximum speeds up to 350 km\/h<\/strong>, with average operational speeds around 250 km\/h \u2014 enabling the rapid 73-minute journey once the system is operational.<\/p>\n\n\n\n<p>To minimise disruption and optimise alignment, a <strong>final alignment survey<\/strong> has already been completed. The chosen route connects key urban hubs and emerging centres across <strong>Tamil Nadu, Andhra Pradesh and Karnataka<\/strong>, providing efficient inter-state connectivity.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Underground Sections and Urban Integration<\/strong><\/h2>\n\n\n\n<p>A unique feature of this high-speed project is the inclusion of <strong>underground sections and stations<\/strong> in Bengaluru. Two underground stations are planned \u2014 at <strong>Byappanahalli<\/strong> and <strong>Whitefield<\/strong> \u2014 to seamlessly integrate with existing metro and rail networks, while avoiding major surface-level disruption in densely populated areas. Additionally, an approximately <strong>12-kilometre tunnel<\/strong> will carry the line through parts of Bengaluru\u2019s urban zone.<\/p>\n\n\n\n<p>Other tunnels are planned in geographically challenging areas, including an <strong>11.5-km stretch through the Mogili Ghat section<\/strong> and a <strong>2.5-km tunnel in Chennai City<\/strong>. These underground sections help maintain high speeds and stable operations while conserving space and reducing environmental impact.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Stations and Connectivity<\/strong><\/h2>\n\n\n\n<p>Major stations set to be part of the corridor include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Chennai Central<\/strong> (starting point)<\/li>\n\n\n\n<li><strong>Poonamallee<\/strong> and <strong>Parandur<\/strong> (near Chennai\u2019s second airport)<\/li>\n\n\n\n<li><strong>Ramapuram (Chittoor)<\/strong><\/li>\n\n\n\n<li><strong>Kolar (Hudukula)<\/strong><\/li>\n\n\n\n<li><strong>Kodihalli<\/strong> (near Hoskote)<\/li>\n\n\n\n<li><strong>Whitefield<\/strong> and <strong>Byappanahalli<\/strong> (in Bengaluru)<\/li>\n<\/ul>\n\n\n\n<p>These stops are strategically chosen to enhance regional access and link economic hubs, supporting both commuter and business travel while fostering economic integration across states.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Impact on South India\u2019s Transport Landscape<\/strong><\/h2>\n\n\n\n<p>Once completed, this high-speed rail corridor will not only cut travel time drastically but also improve <strong>economic integration<\/strong>, boost tourism, and enhance talent mobility between two major metropolitan regions.
