In order to meet growing demand 70 new carriages will be purchased which will take the current total from 20 to 25 trains of 5 carriages each.

From a statement issued by the Panama Metro Secretariat:

Every day of the year an average of 270 thousand passengers use the Metro facilities.  Statistics show a low number of incidents that could affect the service, demonstrating a high level of dependability in all facilities and equipment, which exceeds that of other rail systems, taking into account that it operates for 18 hours a day, 365 days year.

In order to cope with the constant increase in demand, the Government has authorized Metro de Panama, to acquire 70 new train carriages in order to have trains with 5 carriages. With this acquisition, instead of having the current 20 trains, there will be 26 trains each with 5 carriage.
