2.1 Coupler force, Acceleration and Jerk trials for running of 16 nos. LHB AC/CC EOG coaches with two WDP4B class of locomotives between Ajmer-Rewari- Ajmer section of NWR have been conducted and test results as contained in Report no. MT -1404 Rev 0 dated 27.04.15 are found satisfactory. During trials the hotel load of the train formation met by the locomotives connected at either end.

3.0 Based on the satisfactory results above, it is certified that operation of Jodhpur- Jaipur Intercity Express and other similar trains hauled by two WDP4B class of locomotives fitted with hotel load features (one in leading & other in trailing) comprising maximum 17 nos. of LHB AC/Non AC (EOG) coaches (04 AC & 13 Non AC) may be permitted to run on Jodhpur-Jaipur-Jodhpur section of North Western Railway up to a maximum speed of 105 kmph, on track maintained to other than C&M-I, Vol. -I and on track maintained to C&M-I Vol.-I standard subject to the following conditions:

One Hotel Load loco (WDP4B) with 500 kVA capacity would be able to cater to the demand of the entire train of Intercity express, while the other locomotive can work as a standby to provide 100% redundancy for hotel load. The wider trials meant for reducing the running time by improved acceleration and increase the throughput by replacing the power cars with passenger coaches gradually .
