I still don't understand why they want to build rail to Leitrim and continue the rapid transit route as BRT. Just build rail, that will save millions in the long run both in operational and capital costs (possibly billions by the time of conversion) as well as massive headaches during conversion. Look at the pain in the ass the Confederation line construction is causing just by having to widen the Queensway, and they haven't even started conversion, now that's going to be hell!
Here is the planned extension, don't know why they don't put the passing tracks at stations when possible, or in the case of Gladstone, if you have passing tracks, might as well build platforms.
