1) 700mm diameter - broken down vehicles should be shuntable, but a person could get in there reasonably easily.
2) helium blimps lift 1 gram per litre of helium, so to lift 10kg of groceries they would need a 10 cubic meter blimp or a 2.7 meter diameter sphere - seems big and difficult to control especially in winds.

A person could get in a pipe of 700mm diameter? I seriously doubt it.

It's a tight fit but works. I would have to put one arm forward and one arm back to shift my shoulders for a torpedo tube (approx 21in or 533mm depending on nation). 700mm is another 6 inches. The average male's shoulder width is about 18 and go wide as 24 inches (often hard core weight lifters).

1) What is the size of the pipes you are considering? Will it be big enough for humans to get into for maintenance - I was thinking what would happen if a delivery vehicle breaks down or a small animal gets into a tunnel.
2) Have you considered small blimps as delivery vehicles? The technology has got considerably better and should be less noisy than drones.
