OpenRail Concept Station Coordinate System

Hi all,

I have issue about my coordinate system. I couldn't find coordinate system same as my ContextCapture, Kertau 1968 / Selangor Grid (EPSG:4393) + EGM96 (EPSG:5773).

Can someone explain to me.

I have attached 3MX files into  OpenRail ConceptStation, it did not working.
