Option 2

Rail bridge modified; 2.1% grade.

Showing the difference 0.1% grade makes to platform position and track elevation at platform.

 

Using 2.1% grade; McLeod joining Nepean from its’ current position and with the rail bridge modified.

Platform starts 84m past McLeod. This will be taken up with the station building(s) positioned at McLeod and ramp. The ramps for trenches at Springvale, McKinnon etc are over 100m long.

Rail elevation at the platform = -1673mm

The distance between the Patterson River (southern pier) and McLeod Road IS LONG ENOUGH to provide train clearance under the road and return to ground level before the Patterson River rail bridge (where boats access) at an incline that would allow trains to run safely.

Option 3

Rail bridge modified; 2.26% grade.  Still a full 0.1% less than currently on the Frankston line.

Showing platform position and track elevation at platform.

 

Platform starts 10m north of McLeod. Station building(s) can be positioned north of McLeod in the shopping centre area.

Rail elevation at the platform = -943mm

The distance between the Patterson River (southern pier) and McLeod Road IS LONG ENOUGH to provide train clearance under the road and return to ground level before the Patterson River rail bridge (where boats access) at an incline that would allow trains to run safely.

 

Option 4

Rail bridge modified; 2.3% grade.  Still a 0.06% less than currently on the Frankston line.

Using 403m distance, ie. Not continuing McLeod alignment to the edge of the trench.

 

Platform starts 10m north of McLeod. Station building(s) can be positioned north of McLeod in the shopping centre area.

Rail elevation at the platform = -938mm

The distance between the Patterson River (southern pier) and McLeod Road IS LONG ENOUGH to provide train clearance under the road and return to ground level before the Patterson River rail bridge (where boats access) at an incline that would allow trains to run safely.
