Seriously? 2800 passengers per day? On the Crossrail just two trains can transport more people (3000).
And at peak time there will be 2 trains per minute...
Like, I'd be incredibly impressed if they pull it off - I'm just dubious.
Official docs actually say "A train every two and a half minutes at peak time through central London ... trains accommodating up to 1,500 passengers"

So it looks like no. It will actually take crossrail 5 minutes or more to exceed that daily capacity of Dugout loop.
I was always wondering about people running to get the next metro.
The Victoria line has been quite successfully running 36 trains per hour (100 second headway) at peak times for the past year. Peak = about 3 hours each in the morning and evening.
