Abstract
This paper aims to demonstrate the advantages of the Alternate Double-Single
track (ADST) solution with respect to the traditional double track alternative for
railway line design. The paper starts with an introduction and a summary along
with a description of the ADST approach and its main advantages. For illustration
purposes two real cases, which use this procedure, have been described.

The Santander-Bilbao and the Vitoria-Zaragoza line proposals are analysed in some
detail showing the important savings and performances when compared with the
double and single track solutions. Finally, some conclusions and recommendations
are given.

Keywords: Railway line design, rational investment analysis, optimization, rail capacity, relative travel time
