Hello,
Article writer here. For those not yet aware, I have written two major special features articles for RaiseTheHammer, which are:
GO Part 1: Major GO Train Construction for Hamilton
GO Part 2: Weekend All-Day GO Trains Possible In Hamilton 2016
Although the Niagara seasonal train season is now over; it's worth noting that the summertime Niagara seasonal GO all-day 2-way weekend trains
ALREADY (during season) pass West Harbour GO without stopping. 16 trains per summer weekend; including 8 towards Toronto and 8 towards Niagara. So Hamilton could get all-day summer weekend Toronto GO trains too; just by having the return Niagara GO train stop.

This is currently because West Harbour is still a stub of a track:
The work is already funded to extend the track as ongoing work according to publicly available info; approximately similar to this guesstimate of a map.
The question is whether this happens by 2016, 2017, 2018 or 2019 (upcoming Centennial Pkwy station). For such a short extension, it should be sooner rather than later.
This is needed thanks to the
Lewis Road GO Layover Facility, which is being built in Site #3:
Several months ago during the summer, I appear to have been the first person to have ever published construction photographs of the trackage at Site 3, the Lewis Road facility:

The facility completes very shortly (operational 2016), which probably is when they will double the number of peak trains at West Harbour GO (and hopefully an 8:00am train...). As a bonus, hopefully this will also introduce summer weekend all-day GO train service (by virtue of Niagara Seasonal GO trains stopping at West Harbour GO). If not for Spring 2016, then at least hopefully by Supercrawl 2016.
It really is just a short section of track extension, and probably double-tracking of West Harbour (both platforms open), which looks like it could finish 2016 -- except for the potential logistics howstoppers shown in
GO Part #2: Weekend All-Day GO Trains that I wrote for RaiseTheHammer. Working with CN can be a challenge, with all the
We will see if weekend all-day GO service arrives in Hamilton within the next year (and no later than two, at worse case) as a result of the Niagara GO trains stopping...
Exciting times indeed as finally lots of GO construction is happening at 3 different Hamilton construction sites (photographed in
Part 1).
