50 level crossings to be removed

The LXRA is exactly that - it removes level crossings.  It does not duplicate single track sections of 4.7 kms.  It is possible that both projects could be done at the same time, but not necessarily so.  In that event, whichever is done first must make allowance for the other.

Apparenty the duplication near Rosanna is being taken as an opportunity to raise the railway over Lower Plenty road.

No, there's no correlation between the duplication project between Heidelberg - Rosanna & the elevating of the line at Rosanna with the level crossing removal. The fact is the line is being duplicated between Heidelberg - Rosanna which involves widening the embankment and building a new tunnel. The level crossing removal at Rosanna could have either been built rail under or rail over but the rail over solution was picked. This is a part of a combined project called the Hurstbridge Line upgrade and I believe it also includes money to investigate duplication between Greensborough - Eltham.

But both that duplication and grade separation are being done at the same time in that location, so it seems like one is used as an opportunity to do the other.

No, they are seperate components of the one project: http://levelcrossings.vic.gov.au/rail-projects/hurstbridge-rail-line-upgrade

Just because one component is being done is not a cause to do another project. There's a whole range of components that are being completed or initiated as part of this Hurstbridge Rail Line Upgrade project.

Apparently the railways runs uphill and then downhill through Cave Hill station, just before Lillydale. How about a tunnel through that big hill?

No comment on the rest.
Myrtone
This has been thrashed out previously, but there is no Cave Hill station.  And the name of the station at the end of the line is Lilydale, not Lillyale.  The name confusion has also been dealt with previously.

Why on earth would you want a tunnel, when the line could be duplicated for a fraction of the cost?  The gradients are not a problem for today's EMUs, and the hill is not that big anyway.

How can a tunnel be comparable to duplicating the line. You noted this:

There is a long term project for a Lilydale bypass of the Maroondah Highway.  My Melways shows it crossing the railway line near the existing Taylor Street-Melba Avenue crossing.  If this ever goes ahead, it would require a grade separation at that point.

This diagram shows the gradient and makes it look big. If the railway runs through the hill, maybe a road could go straight over it.

Because the vertical distance in those diagrams is exaggerated compared to the horizontal.

An EMU on the 4.5km section of track between those stations is not going to have a problem. Putting in a tunnel to remove what amounts to about 2km of gradients is a waste of money.

The railway is already effectively paralleled by arterial roads, so there would be no point putting another one in.

The road is a projected removal of the Maroondah Highway from the main street of Lilydale, and re-routing it around the back of the shops/CBD.  There is a lot of point in removing the through traffic on this busy highway from the main street.  If it ever happens it would also remove the Maroondah Highway from the existing level crossing, but that crossing probably would have been grade separated before this goes ahead - if it ever does.  The projected bypass is shown on Melways map 38.
