Constructora 6-window

In 1904-06 a total of 24 new tramcars were constructed by "A Constructora". The original numbers were 43-54, 57-66 & 68-69. They were in American style with six windows at each side.

Like the converted mule cars they had longitudinal seats with seating for 22. This configuration of seats gave them their nicknames: Risca ão meio does mean "Divided into halves".

In their youth this series worked on the line to Matosinhos via Foz with up to three trailers.

Their original open platforms received windscreens in the 1920s.

Seven cars of this type came to the STCP (series 105-111, with the CCFP they had the numbers 105, 103, 104, 108, 124, 126 & 205). One (107) was reconstructed in 1952 by the STCP getting extended platforms as can be seen of this photo of 1972 in front of Boavista depot. The 107 is brought back in the original style and belongs to the Massarelos museum-collection.

The 169 on the Praça (detail of an old postcard). The 169 has two trolley poles which means it could be used on the Ponte D.Luiz I. On the bridge the use of double trolley poles was obligatory.
