Honestly I'm not sure, maybe someone with an updated run manual can shed some light on this
@Urban Sky I found a copy on the locomotive engineer's website last year, and posted it here. Someone probably reported it and it got taken down.
I don't know on which side of the border the crews change, but I assume that changing the crews prior to the border helps speed up border checks, as the LEs on the train are entering their own country and have already cleared the border checks prior to going on duty.
Thanks for clearing that up, I completely forgot about that! I was also under the impression that the crews might time-out (fatigue) since the manual indicted a reporting time of 6 am (I normally see the Maple Leaf backing out of the TMC when I'm on 71 in the morning). The train also doesn't get back to the yard until 9pm. That's an 18-hour work day. Do the yard crews deadhead the train to Toronto Union now allowing a reduction in duty time for the engineer's going to Niagara?
First of all, 6am to 9pm (i.e. 06:00-21:00) is 15 hours, not 18, but let's assume that the LE goes on duty at Toronto Maintenance Center (TMC) at
06:00 (as you recall), takes control of the Amtrak equipment and backs it up to Union Station for a
08:20 departure. The train arrives on-time at
10:16 in Niagara Falls/ON and the crew goes off-duty at
10:30 after the Amtrak crew has taken control of the train. That's 4.5 hours on-duty. Then, the crew goes and rests somewhere in Niagara Falls before taking a Taxi across the border to report for duty at
16:00, to take control of the train as soon the train arrives in Niagara Falls/NY., for a departure across the border at
16:26, where the border checks take place in Niagara Falls/ON before the train departs on-time at
17:45. Then, the train arrives on-time at
19:41 at Union Station and the crews back the equipment to Toronto Maintenance Center, where it hands over the train to the maintenance crews before going off-duty at
21:00 (as you suggested). That would be another 5 hours on-duty, thus a total of 9.5 hours on duty during a period of 15 hours, with a break of 5.5 hours in-between. This is called a "split shift" and the only reason why Commuter Rail services can deploy their crews somewhat efficiently...
