So this is neat, listen to the rails in the video plus the 10 locos. Also, I am amazed at the speed if this is next to a yard I would think yard limits apply but I guess it depends if the mainline has those limits.

Train looks to be doing 45-50 MPH. Out of those 8 units up front. The lead unit is probably the only one online in that consist. The other 7 just a power repositioning move.
Not conversant with Canadian rules. If the track being operated upon is governed by Signal Indications then those indications govern with track speed being the maximum allowable within Yard Limits. If the track is in Dark Territory they trains (at least on CSX) are to oprate at Restricted Speed looking out for other trains and/or equipment that may be on the tracks within the Yard Limits even if they have Block or Track Warrant Authority that includes the Yard Limits.
Never too old to have a happy childhood!
There was a day when that many locos would be in the consist, and all on-line. Especially with F units, which were only 1,500-1,800 HP (give or take) vs today's 4,400 HP for one unit.
I agree on the speed - it just seems fast.
It's not unusual to see that many units together, but, as noted, it's a power move, either to reposition for use elsewhere, or for maintenance, or perhaps headed for storage, if a RR is mothballing power.

As I recall CP has a limit on number of powered axles in a consist, on the point and in DP. That would put a hard limit on the number of engines on the line when power balancing.

Back in the days of F's and GP7's & 9's one never thought there could be enough power on a train to exceed the draft abilities of couplers, knuckles and draft gear - it wasn't thought you could build a train 'that big'.
Today it is a real concern and at least CSX has train handling rules limiting how much power can be on line and the trailing tonnage that the power is allowed to haul as well as braking requirment for getting trains DOWN the grades.
The same train going through Alliston... Wow!
Penn Central used to use that many units just to make sure that enough were online at the end of the run to get the train into the next yard.
That's why I liked the, as a locomotive spotter. They had way too many locomotives sitting around for me to take pictures of. I'd go to the Livernois engine terminal at Junction Yard in Detroit on a Sunday afternoon and there's be 30-40 sitting there. The employees were always very friendly, too. The good ole days...

The term "yard limits" disappeared from the rulebook back in the early 1990s, when it was changed from the UCOR to the CROR.
There are numerous locations where a main track with a high speed limit runs right next to a yard. Nothing unusual about it.

Just an observation from a trackside observer!(?).
My point of observatikon, being trackside, is my back deck. It is something on the distance from the closest junction, of what might be considered a speed sensitive point {ie: a switch of 45MPH (?), point of my info was a local R.F. }
W.B. That seems to be correct; w/o stopping..EB limitation is a + gradient of 1% (?) to next E.B. jct .. ] As I have mentioned in othger posts, traffioc through here is either onto, or off BNSF Su. Tcon. Recrews generally at Wellington, Ks. yard, or at JCT @ Mulvane. Ft Worth dispatch, seems to have enough room to /'park' trains here, {Main#3, Eldorado sub}. Maybe, not the greest spot for train-watching, but one can see some curious stuff.
