You don't look had enough

At least northern, jubilee, and central have them.

but if there are they
will otherwise provide room to stand, not wasted space.

Northern, and Central have tip-up seats; the Jubilee has standing
room (which is fairly well used in the rush hour).

If i recall correctly, that is. I don't use the tube as much as I
used to (I tend to use a bike instead).
