Actually ... it's not Remodelado. First Remodelados were built in 1987 with additional ones in 1992 and 1995. Technically, they were not built, but rebuilt from older trams.

This is a Carris Standard 2-axle motor car, built in 1928 and retired in 1995.

Both Standard and Remodelado appear similar, but have several visual differences. The most visible one are the doors - Carris Remodelado have automatic doors, while the Standard ones (depending on the series) can have only a metal gate (like this one has) or manual doors.

The number 548 is reused in a Remodelado, but that was rebuilt in 1995, so it's not on this photo (https://transphoto.org/vehicle/108193/#n104229)
