AMHS Trial and Implementation phase

Contract Signed – 2011

FAT – in end of 2011

AMHS gateway to be installed in first Q 2012.

SAT – after installation

Trial with adjacent countries in 2012

AMHS Implementation scheduled in 2011 -2013

What we need to do

To begin technical cooperation with China for:

AMHS

AIDC

To make Technical solution over existing ground high speed line

To determine target date of star of technical test connection between AMHS

and AIDC

Any Questions?
