Locomotive
It previously ran with WAP-4 loco of Howrah but now mostly gets WAP-7 loco of Santragachi . Before the conversion of Mumbai CSMT to Kasara from 1500 V DC to 25 kV AC, it was hauled by WCAM-3 of KYN shed for that section.
Speed
Its all coaches are of air conditioned LHB coaches type which is capable of reaching 160 kmph but it does not touch. Sometimes people become confused because according to Indian Railways Permanent Way Manual (IRPWM) on Indian Railways website or Indian Railway Institute of Civil Engineering website, the BG (Broad Gauge) lines have been classified into six groups ‘A’ to ‘E’ on the basis of the future maximum permissible speeds but it may not be same as present speed.
The maximum permissible speed is 130 km/h but it is less in many parts of the journey as many parts are not fit for 130 km/h speed. The maximum permissible speed is 105 km/h between Mumbai CSMT and Kasara where increasing up to 110 kmph in future is planned, 60 km/h between Kasara and Igatpuri, 110 km/h between Igatpuri and Wardha, 120 kmph between Wardha and Nagpur , 110 km/h in Nagpur - Jharsuguda - Rourkela route but the speed in this part is under process to be increased to 130 kmph, 130 km/h between Rourkela to Tatanagar, Tatanagar to Kharagpur and Kharagpur to Andul. 110 km/h between Andul and Howrah.
