A new road bridge connecting Station Street to Station Street over the Patterson River is planned.
This can be used as a temporary rail by-pass whilst any changes to the Patterson River rail bridge are completed.
Allowing for a safety fence 3m from the by-pass rail track access to properties either side of Patterson River remain unaffected.
This will require a stronger bridge for the train use but any additional height caused by deeper spans can be accommodated with the more lenient road design rules and/or service road use.
And this is working on a two-track by-pass where train schedules will not have to be altered.
But even with a single-track by-pass all trains can be accommodated.
Total by-pass length <500
Metro train length 150
Total to travel 650
Use a temporary by-pass speed restriction to suit track transitions:
Transit use time in by-pass
At 40km/hr ~ time 59 secs
At 50km/hr 47 secs
At 60km/hr 39 secs
Add acceleration 10 – 15 secs
Red figures indicate new schedule
All changes within 2 minutes
A minimum of 3 minutes between
entry to by-pass end
All trains serviced ~ No bussing reqd.

Changes to the Patterson River rail bridge DO NOT require a closure of the Frankston line for up to six months.
