These are recent pictures of the MRTS (Commuter /Suburban Rail) at Chennai. New elevated tracks have been added, but these pictures are from an old line on the surface, between Beach & Tambaram.
Also, see this link about the system, that has had a very poor beginning, but is said to be slowly picking up now. However, when I had travelled on it recently (off-peak hours), coaches were seen almost empty with very few passengers.

1st Class, but condition of the coach is poor
New Platform, area earmarked for new tracks
Good display of train times, though not always accurate
Rail Depot beyond the fence ?
