Agra-Jaipur : which is the good train????

blusette

Hello,

I try to find the train numbers to go from Agra to Jaipur.
On trains at a glance, I found a daily train 19h55/00h00. But it's a bit too late in the day. There is also a train that runs only on wednesday 7h35/13h30, number 2395 Rajendranagar Ajmer Zhyarat Express.

But, I can't find either of them on indianrailway. This site only shows a train number 2988 17h40/22h20.
I don't understand.

What do you think of it??

Thanks.
Another thing : I've read on the forum that somebody wasn't able to find a seat to go from Delhi to Agra; do you think I should book in advance on internet?
