No idea about 1A of CR Rajdhani, haven't yet traveled in 1A of CR Rajdhani to compare. Had a trip only in 1A of WR Mumbai New Delhi Rajdhani.
But yeah 2A of CR Rajdhani is much better maintained than 2A of WR Rajdhani Trains, comparison can be made as I've traveled 2A of both.
Have you or anyone you know had a trip in 1A of CR Rajdhani ?
