URBAN TRACK Issued: August 13, 2008<br />

Quality checked and approved by project co-ordinator André Van Leuven<br />

rail is obtained with al low exact known <strong>track</strong> stability and is therefore economical efficient Viennese cant<br />

is the only one realized which fulfils all the demands from the bending theory with known forces to keep<br />

it in shape.<br />

The jerks caused by <strong>track</strong> alignment design are continuous everywhere within the vehicle.<br />

It has the simplest mathematical description and is optimal suited for <strong>track</strong> alignment for centre of<br />

gravity.<br />

Modern cant gradient Viennese type<br />

It is the only curve and cant gradient with varying curvature which can be expected to be stable by<br />

reasons of the theoretical demands.<br />
