Beautiful, creative, talented, inspirational and a friend to many.

Those are just a handful of the many words friends, former classmates and teachers are using to describe Anna Damjanovic after her shock death in Brisbane on Friday night.

The 19-year-old former St Andrew's Catholic College died after being struck by a car on an overpass and falling on to train tracks some 15 metres below.

She was revived at the scene by paramedics but today passed away in hospital from the injuries.

In a heart-wrenching post on Facebook, St Andrew's principal Lee MacMaster described Anna as an "amazing young lady".

"She graduated at the top of her cohort in 2015, graduating that year with an OP2. Anna was an outstanding artist, winning numerous awards for her art and featuring in the 2016 publication by the Queensland Curriculum and Assessment Authority publication of highest achievers in Visual Art. Anna went on to study at university in Brisbane. 

"Anna was a much admired young lady in the College community and her passing will leave us empty and in need of healing.

"I feel assured that God is cradling Anna now and sending his love forth for the family. A beautiful young lady, creative, talented, inspirational and a friend to many.

"We will support the Damjanovic family in every way we can over the coming days, weeks and months.

Al"l Saints’ Chapel at the College will be open over the next few days to allow staff, students, friends and community to pray for Anna.

"May Anna rest in God’s love and peace always. She is in our hearts."

The police forensic crash unit is currently investigating the incident.
