I am sure Railways are aware that :
a) this is a smaller train (both in terms of distance travelled and number of coaches);
b) the passenger strength on this train is approximately 60 - 70% only
To highlight, most people in Jaipur and Agra are unaware of such a train operating in the first place.
This should be infact Jaipur - Agra Fort / Cantt - Gwalior Shatabdi Express on a daily basis. The present distance is just 241 kms. and extending upto Gwalior would make it 359 kms either side. A big impediment in smooth operating of present train (19665 / 19666) is at IDGAH which should be removed immediately.
Cleanliness and food is okay.
Railways should look into proper information dissemination regarding the operation of this train and extend it to Gwalior.
