I have some experience with rail in the Bay Area when trains are full, and I'd be very concerned about things like propulsion, overheated brakes, jammed doors and malfunctioning air conditioning when those trains are packed with passengers. Recall that the AirTrain at JFK ran tests with concrete blocks inside the cars to simulate the weight of full passenger loads. Are they doing something like that in the testing process in Rio?
The trains were already in use in other subway lines, therefore that is no need of testing the trains themselves, but rather the new infrastructure of the line.
Sand bags were used instead of concrete blocks for the testing with full passenger load.

The line will receive much fewer passengers than it expects during peak hours of normal operation, since only ticket holders will gain access to it.
