Is the passenger capacity fixed?

As said, a capsule can carry up to 6 people or 367 Kg. But in conventional transportation system, we have more passengers traveling.To be more specific, a train carries minimum of 6 to 7 hundred passengers at a time, wherein the biggest aircraft carries passengers up to 400 nos.. Now, how can this be equated to 6 passengers in a capsule, that too traveling too long distance?

There are several aspects to ET3 passenger (or cargo) capacity:

The standard capsule passenger capacity is one to 6 passengers, with a maximum total weight of 800 lbs.  Standard cargo capsules (without life support) have a capacity of up to three euro pallets (0.8m wide X 1.2m long X 1m high total weight up to 900 lbs.  This optimal weight capacity may be increased (or decreased) by increasing (or decreasing) the size of the magnets in the guideway tubes, and the size of the YBCO elements (super conductors) in the capsule maglev components. 

There are many different airlock designs that have various advantages and disadvantages.  The capacity can vary from a simple home airlock with a cycle time measured in minutes (low cost);  to a dynamic seal airlock capable of admitting two or three capsules per second (higher energy use).  The standard airlock capacity is one capsule in (and out) every 26 seconds.  This is more than 800 passengers per hour.  The standard airlock is a compromise between low cost and low energy use, and high capacity.  One access portal can have one airlock, or many arranged in parallel. One airlock could serve about two airport gates operating at maximum capacity (two 747 aircraft per hour).

ET3 is automated, and uses a 'interchange' philosophy (like a freeway), and NOT a 'switch' philosophy like a train (that limits capacity).  A freeway is limited in capacity by limits of human control and judgment (relating to vehicle speed and spacing).  Automation reliably transcends human limitations.  The maximum tube capacity is a function of the design speed.  At 350 mph it is just over 10 capsules per second. Therefore a single tube can move as many passengers as 20 lanes of freeway with fully loaded cars (2 tube = 40 freeway lanes at 350 mph).  This is over 200,000 passengers per hour in each direction if capsules are filled to the maximum of 6 per capsule.  This is ten times greater capacity than a high speed rail line.   At 700 mph it is a little over 20 capsules per second. 

A key advantage to ET3 capacity is that it is scalable in much more granular increments than trains (600 passengers) or airliner capacity (100 to 400 passengers).  The access portals can be added as are exits on a freeway (as opposed to an international airport, or train station).
