The final four level crossings have been removed and trains are stopping at the new Murrumbeena and Carnegie stations.

Boom gates at Poath, Murrumbeena, Koornang and Grange roads are a thing of the past as trains are running on elevated rail through the entire Caulfield to Dandenong rail corridor, the busiest in Melbourne.

Previously, the boom gates were down for 87 minutes during each two-hour morning peak.

In the last five years, there were 120 accidents or near misses reported along the nine Caulfield to Dandenong level crossings.

Metro, V/Line and freight trains will travel along the six kilometres of elevated rail.

The construction teams will be putting the finishing touches on the new stations and public spaces over the coming months.

Twenty-three level crossings have now been removed with two more – Skye/Overton Road, Frankston and Thompsons Road, Lyndhurst – set to go before the end of June.

The total will be brought to 25, which is half of the level crossings scheduled to go by 2022.
