actually firstly it starts from kota at 11.55 pm with train number 59801 kota-phulera fast passenger,reaches jaipur at 4.30am then after reaching phulera after 1 or 2 hour it again started from phulera on same day with train number 59802 phulera ratlam fast passenger both 59801 and 59802 is fully reserved with gs coaches then it reached ratlam around 2 pm next day then from ratlam it runs a unreserved passenger upto kota with train number 59803 so it is unreserved, after reaching kota either it runs as a kota nizamuddin special or one pair of this train goes to jaipur again journey started now you can think that this train timing is very congested means no time to de attach ac coaches thats why ac coaches comes empty from ratam and goes full from kota to rtm or jp or nzm.
