Very interesting analogy, although perhaps taking a bit of imagination. Perhaps a subway station would be a better analogy. I'm thinking of the capillaries being trains, perhaps the Red blood cells being the train cars. The alveolar/capillary walls and the pores of Kohn would be the doors. The Alveoli would be the walkways. Air being crowds of people milling about. As the RBC's pass by, the Carbon Dioxide gets off the train, passes through the capillary walls and into the alveoli joining the crowds of "air" milling about, while oxygen passes the other way. I believe it is all a passive process. So the boarding / deboarding is only a will to go where fewer Oxygen or Carbon Dioxide molecules are. And in theory it could be two way with excess oxygen getting off, and perhaps reboarding. And Carbon Dioxide getting off and back on too. But, in general, more carbon dioxide gets off and more oxygen gets on.

Popularly called MegLev there are two different modes of operation. When the train is still at the station it can be held by magnets. In motion electromagnets are like an electric motor that has been flattened out. The stator on the ground ( the tracks ) and the rotor being the train. The train is confined with magnets and electromagnets. The linear motor can be in the train, "the tracks" or both. Preferable would be a combination with the tracks pushing and levitating the train along with permanent magnets. The train with balancing magnets and electromagnets to keep it in the track and going. There is a way of putting the magnets together with their fields at right angles to each other. This puts the magnetic force on one side.
I like to squish boobies!!!!
Magnetism elevates the maglev train because like forces repel. Maglev trains are not suspended, but are elevated.
When it is not parallel. Parallel is when it is two straight lines: like train tracks are antiparallel, when it is going of course: Like a trapezium.

A train station in Spain
In a small cafe beside a train station, in Spain.
Yes it is. It is one of the biggest train stations like EVER, and it's also a train company.
I would like to know if there is a train from rome to monaco what train station in rome and the schedule.

Birth control advocate Margaret Sanger views newborns as refugees in a train station.
Complex sentences have extra clauses inserted like this; The train, which wheezed like an old man, left the station. Simple sentences only have one clause, like this; The train left the station.
it means like a pitt stop for example train station.
A railway is like a train station where trains pass and go.
A train station in Spain
There is a shuttle bus that runs between the train station and the airport. I think it costs something like 3-5 euros. There is a sign outside of the station that lists the times. If I remember correctly, it runs about 4-5 times a day. If the shuttle isn't running, there are always taxis waiting by the train station that could take you.
