Randwick Council is hopeful of saving a small park slated to be used as an interchange for Sydney's new light rail line, but may lose a battle to preserve a large row of historic trees on the edge of Centennial Park.

The council is in negotiations with Transport for NSW and the consortium building the light rail line from the city to the eastern suburbs about moving the planned interchange at High Cross Park.

According to one councillor, Murray Matson, the department has signalled that it is open to moving the interchange, with major construction on the line due to start within months.

"We are getting very positive feedback," said Cr Matson, from the Greens.
