======== WAP-5 in a Nutshell =======
The Loco Story :
Imported from ABB Zurich, Switzerland (30000 - 30011). Later Chittaranjan Locomotive Works started indigenous production in 2000.
Maximum speed limit - 162kmph. Top Speed - 225 kmph. Maximum power output - 5450 hp.
Designed
...

to haul 18 coach passenger trains at 162 kmph making it the fastest locomotive in Indian conditions. It is the first 3-phase locomotive class in India.
Provision of taps from the main transformers for hotel load, pantry loads, flexible gear coupling, wheel-mounted disc brakes, and a potential for speed enhancement to 225 kmph.
Braking systems include regenerative braking (160 kN), loco disc brakes, automatic train air brakes, and a charged spring parking brake.
Fastest train of India the NDLS-Bhopal Shatabdi hauled by a WAP-5 which travels at 160 kmph.
The original design was to have air-conditioned cabs. However the idea has been scrapped due to controversy over costs and fitment and the first units made by CLW do not have air-conditioned cabs. As of now only WAP5 # 30000 have ac cabs.
Technicalities :
Traction Motors --- ABB's 6FXA 7059 3-phase squirrel cage induction motors. Forced-air ventilation, fully suspended. 96% efficiency.
Transformer --- ABB's LOT-7500. 7475kVA primary, 4x1450kVA secondary.
Tractive effort --- 258 kN
Power --- Power convertor from ABB, type UW-2423-2810 with SG 3000G X H24 GTO thyristors
Conductor --- ABB Thyristor
Axle load --- 19.5 tonnes
Loco weight --- 78 tonnes
Bogie type --- Bo-Bo Henschel Flexifloat
Pantograph --- Two Stone India (Calcutta) AM-92. Schunk for the imported locomotives.

Re# 1716717-2              
Some corrections (after verifying from various sources like IRFCA, RDSO, CLW)
----------
Maximum power output : 6000 HP
Continuous power output : 5440 HP
Max permissible speed : 160 km/h (except loco 30086)
Max

more...
tested speed : 184 km/h (except 30086)
There's only one loco capable of breaching the 200 km/h mark and that is GZB WAP5 30086. Only this loco can touch 225 km/h.
Also, ABB "never" specified how many coaches a P5 is supposed to haul :P
