                              Abstract
                              Having different gauges on a railway network is a difficult challenge for planners
                              and operators. There are a set of tools that can be used to minimize the connection
                              problems at gauge frontiers. For HS, the solution has come through automatic
                              gauge changing trains. For freight there are other solutions working now such as
                              static wheel changing at frontier and third rail, but each has its disadvantages and
                              there is need for enhancing the array of tools at the disposal of the infrastructure
                              planners and decision makers at the transport ministry.
                              The Spanish rail authorities have decided it is time to develop an automatic gauge
                              changing  technology  for  freight  trains,  and  they  have  put  forward  a  program
                              that aims at having a certified variable gauge wheelset by the end of this year.
                              ADIF awarded the consortium formed by the Spanish companies TRIA and AZVI
                              a contract to develop and homologate two variable gauge wheelsets for wheel
                              diameters of 920 mm and 760 mm, that mount on Y21 bogies in the case of the
                              920 mm wheel and on vehicles carriages in the case of the 760 mm wheel.
                              At  this  moment,  the  prototype  train  has  done  20  thousand  kilometres  on  the
                              HS and conventional networks of the 250 thousand required for final approval.
                              Previously, the wheelsets have passed bench tests and the gauge changing tests.
