Now if the train does 1 lap every 20 seconds, it'll spend 2 seconds travelling through the station each lap.

But here's the rub, in the first instance if you increase the time measured to 20 seconds, then it spends exactly the same amount of time in the station as the second loop.

Numbers only:
1 lap every 20secs, 2 secs in station per 20sec
1 lap every 10secs, 2 secs in station per 20sec

Ultimately the flowrate doesn't make a major difference to the time water spends in the radiator, which is why flowrate doesn't make a difference.

Flowrate makes a difference with waterblocks, not radiators.
I think you need to do some reading too. Step 1, reread what I wrote and what I was referring to. You asked me if I was kidding? Closed loop? Yes the assumption is a closed loop. And flow rate DOES make a difference in radiators. Please check your facts.
