Travelled by 2 tier A/C on Sept 15th from Nizamuddin to Trichur. Food was good.
However the only one 2 tier coach was in poor shape. There is no A/c temperature control, either off or on, and coach was a 1995 one. Cleani9g staff board at stations and clean the side window glasses, asking the passengers to get up and make way for them! Still the windows were not clean!
3 tier coaches are new, more efficient A/C control.
