There is currently no rail transport system on Gran Canaria. Between 1893 and 1944 steam tram ran between Las Palmas and Puerto de La Luz. The line was electrified in 1910, although the line reverted to steam traction in 1944, when trams were hauled by a steam locomotive known as "La Pepa". A reproduction of this locomotive is now on display in the in Las Palmas. In the early 1970s an experimental elevated railway line operated through Las Palmas. Called the "Tren Vertebrado" ("vertebrate train"), it was designed by Basque engineer Alejandro Goicoechea and consisted of an unusual low-profile train running on elevated concrete tracks through the city. The project was unsuccessful and was dismantled in 1974.
