Seaford Road Level Crossing
Rail Under Road
Another 8 level crossings on the Frankston Line are due to be removed. Three have already been grade separated with a Rail Under Road solution: Ormond, Bentleigh and McKinnon. This article explains how Seaford Road can be Rail Under Road also.
1. Rail Reserve
• A 40m wide railway reserve allowing “parallel” construction, similar to new Springvale station.
• A rail trench can be constructed alongside the current rail line which can remain in use.
• This would cut rail closure to just a few days to dig under the road.
2. Ground Water
• Groundwater levels are similar to current Rail Under Road sites (ie: Ormond) so can be dealt with as per other Rail Under Road projects.
3. Soil Type
• Local soil type (which may or may not be Acid Sulfate Soils) has supported railway operation for over 100 years. A correct concrete mix can be adapted for all conditions.
• Soil type (sand) can be supported with proper pile foundations, correct concrete mix, and soil anchors (as per Ormond.)
4. Roadway Clearance
• Only a 6 metre clearance is required to put Rail Under Road compared with 9 metres for Rail Over Road (aka Elevated Sky Rail.)
5. High Voltage Power Line
Groundwater Depth: Could be as low as 4 to 5 metres below average ground level.

Soil Type: Coastal Dune Deposits (sand)

Traffic Volume: High, 17,400 vehicles/day 210 trains/day. Boom Gates down for average of 32 mins between 7am and 9am. (Source: LXRA community consultation information displays)
Other Factors: Kananook Creek 200m to the west of the crossing.
Rail Under Road – Advantages
• Rail Under Road will also reduce, rather than increase, air-borne pollution.
• A rail trench will be much quieter than elevating the rail 9 metres in the air.
• Less visual pollution and less opportunity for graffiti
Retain Property Values
• Property values will be preserved or increased, rather than facing a 20% decline as predicted with Sky Rail, “elevated rail” or railway bridges
Less Council maintenance and increased rate revenue
• No extra cost to council for cleaning (graffiti, removing dumped rubbish, etc) under an elevated railway bridge if the crossings are put in trenches.
• No loss in rate revenue as property values will not decline.
• A Rail Under Road option will be a proper long-term infrastructure solution that will increase the amenity of area and leave a lasting legacy that will not be an eye sore for generations to come.
