Santiago Metro Line 2 was extended to Hospital El Pino

Metro Line 2 runs parallel with Metrotren(Suburban rail). Extended section is also along with Metrotren.
I don't if the line is extended to somewhere on Metrotren.
By the way, Santiago Metro Line 2 has Express service. Red train skips some of the stations where Green train stops. On the other hand, Green train skips some of the stations where Red train skips.
