Facilities are going to be substantially better than anything that can be done with Eagle Junction - 2 concourses, straight and wide platforms.
Wooloowin and Albion passengers don’t have to backtrack to reach CRR stations.
Albion has and will have more density and activity happening around it than Eagle Junction
I think there’s even an argument to not stop Sector 1 trains at Eagle Junction (at the cost of needing to backtrack slightly or do a double transfer to get to the Airport or Doomben).
I guess the physical layout of the stations is a good reason, but I don’t think the network connections are any better. I would not like to see Eagle Junction skipped as the best connections to minimise total journey length should always be preferred. It would be a bad outcome for people from the north to have to go all the way to Albion just to get on a train that backtracked all the way back up to the Airport line.
I can see it becoming a major interchange if my plan for a Northside rail tunnel under lutwyche and Gympie road ever eventuated, which it won’t thanks to a stupid road tunnel that is also planned to use that same alignment
Judging by that metric, then it would also make sense for SC and Redcliffe trains to stop at Nundah instead of Northgate. It definitely hurts to see a large cluster of high-rise buildings only being served by an off-peak frequency of once every 15min while Northgate, being a more accomplished interchange, is in the middle of nothing spectacular (just a few Queenslanders and industry).
If Nundah station would receive a proper station upgrade, I would love to see QR resume the park and ride to realign track 4, widen platforms 3 & 4, and make the station significantly more accomplished to serve the high-density suburb. Afterwards, the SC and Redcliffe trains will bypass Northgate station. So not only the Sector 1 trains will stop at proper interchanges where passengers can transfer to Sector 2 trains, they will also serve two of the densest suburbs on the rail corridor.
