Tube lines seem to have a headway of 2 minutes and a typical Tube
train has 7 or 8 cars.

Frequencies on the Tube are often lower off-peak and the coaches are
a bit shorter.

I can't see it making much difference, though. The Merseyrail
loop/link tunnels are newer, larger, better-ventilated and cooled by
the water. Even with more trains I can't see them getting as hot.
