There is only one Express train at night time. Compare with today's traffic with innumerable halts for crossings on a single line at night. And what does D.S.Y. stand for?

Olavvakot (today's Palakkad Jn.) to Palghat Jn. (today's Palakkad Town) used to have both BG and MG services.

The MG Nilagiri Express between Mettupapaiyam and Ooty used to run till a few decades ago with number 35/ 36.

The Tarikere- NR pura tramway no more exists since the Bhadra dam submerged the rail lines. But during summer, we do occasionally get to see a railway bridge which used to cross the river.
This line was built by the British to transport teak wood from the deciduous jungles of the Muthodi range (Chickmagalur district,Karnataka).

Is this South Indian Railway official time table? Can you scan the cover as well? Thank you.
