Can anyone explain why Merinda Park Railway Station had to be rebuilt In the opposite platform configuration (requiring the most amount of work / expenditure) ?
The Railway Station was designed / built as an Island platform with a disused platform face (yes sure It would of needed a full refurbishment and extension)
Why would they build a ground level island platform these days?
I suspect that's not the reason at all.
For example Williams Landing and Caroline Springs stations were built island platform, but don't necessarily have 3 lifts involve, either they have ramps involve and some lifts too.
The LXRA team have upgraded stations with island designs before such as Blackburn and Essendon stations. Though I'm disappointed they didn't add some lifts to the Essendon station like they did in Blackburn (out of scope reasons they told me).
Honestly the alignment of the Bridge piers on the Thompson's road bridge favors a two track alignment straight in and platforms on each side. Honestly the blame is not typically the LXRA for rebuilding the station, it's more along the lines of: "every infrastructure being built needs to be built in mind of further enhancements".
The fact the Cranbourne line being electrified was essentially on Federal money and no state contribution meant we got a poor design outcome where they essentially didn't accommodate the future needs of the area. With state contributions by Jeff Kennett, could of duplicated the whole line in the same process, but now have to rebuild again.
Why did it even take 15 years to reopen Evans road, the state government could of resurfaced the road on the level crossing and reopened it many years earlier? Once again railway infrastructure was neglected for a very long time.
This is kinda why I'm so happy to finally see investment into the railway infrastructure, it's been neglected and built cheaply in the past. Now we can rebuild the network back to modern standards.
