I was referring to the entire stretch from Bayview to Stuart (West Harbour), which is ready for track. The Hamilton to Confederation stretch needs the basic civil structural work completed (bridges, culverts, grading) but it is a more recent project so isnt as far along.
I'm sorry, but I'm not at my computer this week otherwise I would offer some pictures. Here's my sidewalk superintendant analysis.
Basically, the whole West Harbour- Bayview stretch is now graded and a certain amount of new track has been laid at the Hamilton end. The new interlocking at Stuart is installed and commissioned, but the tracks are not yet in the final configuration there. The new signals are erected but not wired or cut in, except at Stuart.
What would likely come next is to tackle the interlocking at Hamilton Jct, which needs to be extensively reconfigured to add a new track through it. This will require new crossovers as well as relocating the connections to the CP line. The Ham Jct/Desjardins interlocking is pretty complex and I would expect a whole new configuration with plenty of new switch panels, a new signal bungalow containing a whole new interlocking 'machine', and all new wiring throughout. Typically that kind of interlocking replacement takes blocks of concerted around the clock effort - often a long weekend or successive weekends are used - with the line possibly totally shut down for much of that work block.
Also, the section from Hamilton Jct to Bayview will have to be laid, and insert a couple crossovers and switches at the Bayview interlocking.... a whole second work block, I would expect.
Then there is a certain amount of track shifting to achieve the final configuration. And then the signals have to be wired, tested, and placed in service. And the track must be tamped and surfaced to allow full speed operation.
CN would need at minimum to supervise the work and in particular seems to like their own signals personnel to handle things. This would likely require a lot of weekend overtime for those people. They have their own projects - a lot of the older CTC has been replaced over the past few years. And they have been doing the GO extension up the Bala Sub. They may draw people from around Southern Ontario, but there are only so many hours in the work year.
My guess - It's likely not until 2018 that this kind of scheduling could be made to happen.
