Depots

	Depots & power stations Except for rails and overhead wires, trams also need depots and workshops for maintenance. In Porto for a long period the electric energy was generated by dedicated powerplants. In this section a brief overview is given of the most important of these buildings.
	Depot at Largo do Ouro. On the postcard of which this picture is a detail, the sender wrote the date 21-8-04. So the photo must be made in a winterperiod (notice the tree) between 1896 and 1904.	The oldest tramcompany, the Companhia Carril or the Companhia de Baixo, had a depot at the river near Largo do Ouro (Largo António Calém). This complex was still in use after the merging of both companies. Other depots were located in Foz and at Cordoaria. The second company, the Companhia Carris or the Companhia de Cima, did have several stations. One was at the first end of their line to Foz: Cadouços. Except for the tramservice, here als was a restaurant owned by the CCFP. Also at Fonte da Moura was a small station. For the exploitation of the urban mule tram network, beside Boavista, there was also a depot at Bolhão. This was closed with the electrification of the network. Boavista The most important site of the classic Porto tram was Boavista. There is a dedicated page.	The tramstation Cadouços in Foz. The photo is made between 1874 (opening of the line) and 1878 (start of steam traction).
		Arrábida Electricity was for a long period generated by CCFP owned power plants. The first power plant was located at Arrábida. The coal was delivered by ship. By 1912 the capacity appeared to become insufficient and the CCFP decided to built a new generating station. Arrábida was also used as depot and workshops for the first electric trams and their trailers. The old buildings at Arrábida did get other industrial use, but were demolished in 2000.	During the annual parade (May 2000) the museum cars 22 & 104 go by the derelict buildings at Arrábida in which once the first power station was situated.
		Massarelos In 1915 the CCFP inaugurated the new generating station at Massarelos. There is a dedicated page.
	The former substation Castelo do Queijo. For some period the permanent way department was situated here.	Substations Besides the large generating stations Arrábida and Massarelos also substations situated on strategic places were used. The CCFP did install these at Massarelos, Castelo do Queijo, Telheira, Contumil, Corpo da Guarda and Santa Eulália. The last substation replaced a small power plant in São Pedro da Cova in 1929. This power plant was opened in 1918. With change for the 15 kV supply from the grid, the STCP installed 12 new sub stations.
