What was you most memorable train journey in India?

For me it was From Ajmer to Chittorgraph on a narrow gauge track. It was like a toy train going deep into the night. The berth was occupied with a newly Indian web couple, they seem to be having some difficulties in adjusting to married life.
The journey went on like that in surreal fashion. The married couple looking for advice from a couple that just meet a few months before. What did we know? The berth it self was mini size and almost cartoon like.
