It's damn impressive that they've gotten this far with the project. I don't think many people expected all 50 to be removed, and it really looks like that's going to happen. I wonder what the total will be at by the next election. Considering the additional crossings that will be removed on the Mernda and Upfield lines I reckon it might be closer to 55 or even 60. You'd think that they'd keep going to remove 100 by 2030, which is very doable considering they've effectively already won the 2022 election so only really need to make sure they win the 2026 one. I wonder which crossings they would add. It would be very tempting to eliminate all remaining crossings on the Sunbury and Pakenham lines. You'd think that Macaulay Rd and Puckle St couldn't be ignored for much longer. It would be pretty easy to get rid of all the crossings on the Melton line with road-over bridges, meaning that the entire Sunshine-Dandenong group could run level crossing free.By 2022 there should be 65 gone. Taking into account all of the promised ones, by 2025 there will have been 78 done, to which you could add three in Geelong if so inclined, although 2 of those are not expected to be completed until 2028.
Should the Baxter electrification project get up there would be another 5 done by whenever that gets scheduled for completion. Closure of the original line through Wallace and Bungaree removes 4 more, if you want to count them.
The Frankston line will have only 10 LX left after 2025; eliminating the two remaining tramway squares; Madden Gve in Burnley, one on the Vicroads high priority list; Coolstore Rd Croydon which had a business case done by the local council; Bedford Rd Ringwood which just begs for rail under to eliminate a steep grade on a tight curve; the remaining 4 or so on the Sunbury line; and those standouts remaining on the Pakenham line, as reubstar6 suggests, are all good candidates for consideration for another round of removals. There are probably others that I haven't looked at like Spotswood, Yarraville, Gaffney St on both Upfield and Craigieburn lines that could be considered.
