Last Thursday and now this afternoon, Go Trains on the midday Aurora/Union service were operating to as far north as Maple GO with GO Buses taking people to King City and Aurora with those other bus connections to/from Barrie. This is all due to freight train traffic.

 

Now, I'm not as knowledgeable in freight train lines, but how would a freight train find itself on the Barrie Line? This much I know is that the line is CN. Newmarket Subdivision, correct? I'm unsure where those freight trains would find themselves on the line from?

A freight train would find itself on the Newmarket Sub by travelling along the tracks from another subdivision or yard and taking a switch that leads it onto the Newmarket Sub. Same way that a passenger train would.

There are still a few industries and companies along the Newmarket Sub that are served by freight trains. I photographed a CN freight train north of Rutherford GO just two weeks ago. Since the Newmarket Sub is only a single track, any time a freight train needs to do drop off/pick up some cars or do some switching, they need to stop passenger traffic on the line. And since train service now runs 7 days a week from 5:18am until 11:49pm, it isn't possible to move all the freight traffic to the 5.5 hours a day that trains are not running.

For the sake of convenience, I’ll leave this here: Total of 5 ex go 8000s being loaded in Agincourt yard this morning, destined for their second lives in parts unknown. Numbers still on, th

omg I think its time for some social distancing for you two

Indeed, this is now what the situation is. There is a scheduled job on Mondays and Thursdays that leaves MacMillian Yard around 10 am and switches the industries along the Newmarket Sub, sometimes going as far north as Bradford. CN doesn't have their change of card until April, so it's likely that this will continue to impact the mid-day GO service until then.

Go didn't know that a CN local is scheduled on the same line at the same time? 

I guess it would only impact trains north of Aurora GO? 

 

Reverse - I think it's more that CN may not have had enough notice to change its crew schedules to not affect GO's midday service. @smallspy likely has more details than I do on this.

Because there are no GO trains north of Aurora during the midday, any deliveries north of Aurora do not impact GO's service - the freight train can easily fit in between GO trains, as the scheduled pass point between GO is south of Rutherford (and there is another passing siding between Maple GO and Kirby Rd). The real issue is when CN needs to do deliveries to customers on the section of track south of Aurora GO (and yes, there are rail-served industries on that section). The freight train will need to occupy the single track, preventing any GO trains from passing. And no, it's not possible for the freight train to either 1) quickly pull into the siding for the GO train to pass, or 2) go up, drop its cars and return to the passing track in between the train frequencies.

Sorry what's a "change card"? Is that for a crew change? I assume that because the workers are unionized, there's a process to change schedules?

The "Change of card" is the method and process used to allow crews to change their jobs on a scheduled basis. Very much along the same lines of the board periods of a transit agency.

 

There are two change of cards on CN - end of April, and end of October. There are several other ways for crews to change the job that they are holding without waiting for a change of card, but the change of card allows all crews to change at once.

 

GO used to follow CN's change of cards when they were operating the trains, but now that Bombardier is running the trains they can change the schedules any time they need to.

On Friday 647 had been out on its own with a 10 pack.

it was on the 8:13 leaving to Oshawa, really quiet and it gets up to speed quicker

Yes I saw it today and just wanted to post that as well :D

I think most of (maybe all of) the carriages are in the new two-tones livery.

If that is so, then it is highly likely that both of its engines were running. A single engine generates less electricity making it harder to haul (and hence slower acceleration). Personally I would suggest to GO's engineers that to minimize energy consumption one engine should be shut off during off-peak service except perhaps when hauling full 12-coach trains or during special services.

I wonder at which point they'll start putting the new Metrolinx logo on. I think we could see it debut with the first production MP54ACs before they expand it to newly delivered BiLevels.

I think GO does what they do for a reason...

You yourself said it would make it slower, and the there's a big gap between the single 2700hp motor in the MP54 and the standard 4000hp in the MP40s. That has potential to cause delays, even during off peak hours, and will most certainly have greater fuel and energy consumption. The reason it has two motors is when there are periods of low power demand, one can be shut off for better fuel econ. That doesn't mean they'll be using the one motor to haul it from rest; that's a period of high power demand, regardless of on or off peak service. @smallspy can explain better than me.

The EMD 710  cubic inches (11,600 cm3) per cylinder, 11.6X16=185.6 Liter in the engine.

Two Qsk 60= 2x60= 120 liter, 

MP54AC have smaller engine than a mp40-3c.

Did a bit more research, and found that the 5400hp is divied up for multiple things. 4000 is for pulling effort, while the remaining 1400 is used for other systems on the train, like lighting. Think of it as an APU on an airplane. The max power that can be sent to all 4 wheels is 4800hp. 

The MP54 is equipped with auto start/stop.

They are engine sound like SC-44 right?

I wouldn't quite compare it to an airplane's APU. The HEP on the MP54 is generated by the main engines, whereas the MP40PH-3C and MP36PH-3C units have a separate Caterpillar HEP genset (which is a bit more like an APU).

In my opinion they sound like vacuum cleaners (and the same goes for a lot of Tier 4 engines these days).

No, the maximum power that can be sent to the 4 traction motors is ~5400hp minus HEP and conversion losses.

 

The HEP requirements for the train, be it a 2-, 6- or 12-car train are then removed from that number. The remainder is routed to the traction motors.

Didn’t they tried putting wi-fi on select double deckers a few years back? What was the outcome of that trial period?

 

 

Yes, they tested WiFi on 10 DD buses on 2015, specifically ones that traveled on the 407, or on the Waterloo-Mississauga routes. 

The WiFi service will be entered in March on 2 trains and 4 buses to acquire customer feedback and quality of service. They'll be expanding from there.

That wifi wasn't hydrogen powered... so now we start over :)

GO Transit is highly unlikely to order hydrogen-powered DDs though... not at least till the necessary infrastructure becomes widely available.

Unless you hire the same guy who killed off diesel-electric "Boris buses" and make a deal with a rival manufacturer who never shipped a DD to America...
