So, I guess, the "cost benefit" analysis that would need to be done is "which is most cost efficient and, relative to cost, provides benefit to the most......spending additional money revamping the ARL into a local service or spending additional money (that is planned to be spent by 2018 anyway) accelarting the installation of the 4th track so that the GO service can be upped to provide that hybrid local/regional service".
I am not smart enough to know the answer.
A fourth track, even if it were imminent, would not give us infill stations, smaller trains, 15-minute headways, connection to the airport, electrification, or fare integration, all of which are needed before this line could become an important part of the *Toronto* transportation system. All of that is a long way off any way. But the ARL will stand in the way for a much longer time. And anybody who thinks Metrolinx will be quick to convert an underperforming ARL into a true local service just doesn't really get how bureaucracy works.
