Bonus Dream:
Better yet, make the system so flexible that during future mistakes, the Georgetown train can become the LSW train, and vice versa.
<future-scenario>
- T+0m0s
- "we got over 1000 LSW boarders on a kitchener train mistakenly berthed at this platform"
- decision made to swap
- *clicks swap train procedure*
- displays go "Pending update..." (time boards, platform entrances, platform displays, on-board displays)
- Permission request automatically dispatched for granting. greenlighted by operations/CTC within 30 seconds (train capability and fuel verified remotely, berth accessibility to each route, automatic verification of cascading delays can be kept limited, etc)
- T+1min44s
- Still-approaching LSW train now earlier told to approach Kitchener currently-vacant original berth instead -- finally clears critical crossover. Train did not miss critical crossover, makes it towards reassigned berth
- All permissions green. Berth swap greenlighted
- All displays instantly simultaneously sync, Union wide. Confused commuters now see platform numbers, including video signs at every platform entrance.
- T+2m1s
- Currently berthed Kitchener train now becomes LSW train
- Crew was earlier automatically messaged of developing situation (on some kind of a dispatch display), told to swap cabs if needed, if crew is supposed to stick to route. Thanks to Bay Concourse stairs neing near the cab, cab crew swap lasts only 30 seconds. Enough time left for basic cab check of already-operational train already confirmed to have enough fuel for its new route
- T+4m31s
- train departs under 5 mins late
- Cascading delay: Only three trains delayed by this hypothetical juggle act, longest delay was 4 minutes and 31 seconds due to crew swap. All other trains were simply affected by unexpected crossover activity underweny only a minor waiting delay in the upgraded USRC. 4,000 fewer angry commuters.
</future-scenario>
Science fiction? Maybe not in ten or fifteen years...
The flexibility is good for all kinds of other (more frequent) reasons, we need better Union operations during RER.
