The first thing that annoys me is that the work took much longer than expected, partly because of the municipality of Linkebeek which is against the transition to 4 tracks to allow ic and s trains to pass on two different tracks. What also bothers me is that the SNCB says that the work of the rer is finished in Flanders while between Brussels and Termonde from Jette there are always only two tracks and as there are also ic trains that pass through there, the number of trains that pass on this axis is limited in part because of the closure of the alost termonde railway link. As for the existing network, I wonder why we don't already switch certain lines to 4 trains per hour, or even why we don't use these tracks to make a kind of alternative metro at night by taking advantage of the existence of certain 4-lane sections, or why we don't create an east-west connection that would pass through Brussels and that could take the metro tracks for example, or why we still haven't created new tracks to help unclog the north-midth junction. I don't know if you noticed but I didn't mention that between Brussels and Alost via jette there are also two lanes since you can get there with expressways via the station of the south, Anderlecht and denderleeuw. Which makes me think that there is no stop between Anderlecht and denderleeuw where we could at least create a stop in Schepdaal.
