The "El", a local abbreviation for Chicago's Elevated Mass Transit train system, is one of the most popular forms of mass transportation across the city. While the majority of the tracks are elevated above the ground, the Red Line train does go underground and can be considered a subway, so you can ride the rails while remaining above the surface most, if not all, of the time.
As you can see "the Red Line train" is a train which travels along The Red line system, and the system is made up of Tracks and lines and the trains are the People movers in the system.

When a Monorail is a elevated train (it usually has a cushion of air between it and the track, elevating it above the track as it travels along the line ) on a single rail and it travels on a line from point A to point B.
Just making sure the asker gets the correct English terminology. El = Elevated Line, E for elevated and L for Line.

Not being picky, but a train runs along a Line or on a Track. EL would mean Elevated Line. An Elevated Train is a train which runs above a Track on a magnetic field Ie; Elevated above the track. The track is the steel part of the line, the line is the pathway the train uses to run on the tracks, Ie The Cleveland Line has 12 stations and 2 sets of tracks.
